Best Easy Bourbon Peach Cobbler Sheet Cake with Glaze

Late August, and the only thing I want is this bourbon peach cobbler sheet cake with glaze. The peaches on my counter have finally reached that perfect point—soft enough that your thumb leaves a slight impression, fragrant in a way that fills the whole kitchen. I had bought too many at the farmers market last weekend, and now they were practically begging to be used. Not for jam, not for grilling, but for something that felt like the end of summer itself.

I started pulling out ingredients before I even had a plan. Butter, brown sugar, a bottle of bourbon that my husband bought for Old Fashioneds and never finished. The sheet pan came out next—because honestly, I didn’t have the energy for a fussy layered cake. I wanted something that could feed a crowd without requiring a pastry bag or a cooling rack situation. And I wanted it to taste like the kind of dessert you eat on a porch while the sun goes down, with cicadas humming and someone’s phone playing old country songs from a speaker.

This bourbon peach cobbler sheet cake with glaze is what came together that evening. It’s not fancy. It’s better than fancy. It’s the dessert you make when you want people to feel taken care of without you disappearing into the kitchen for hours. The peaches get jammy and caramelized in the oven, the bourbon adds this warm, vanilla-tinged depth that plays off the brown sugar, and the glaze—well, the glaze is the part that makes people close their eyes when they take a bite. I’ve made it three times since that first night, tweaking here and there, and I think I’ve finally got it right. Or at least, right enough to share.

Why You’ll Love This Recipe

Let me tell you why this cake has earned a permanent spot in my late-summer rotation. First off, it’s a sheet cake. That means no layering, no complicated assembly, no wondering if your cake is going to slide off the stand mid-slice. You mix, you pour, you bake, and you’re done. It’s the kind of dessert that makes you look like you tried really hard when really, you just followed a straightforward recipe.

• Quick & Easy : From start to finish, this comes together in about an hour. Most of that is hands-off baking time. Perfect for when you need a dessert for a last-minute gathering or just a Tuesday that feels like it deserves something special.
• Simple Ingredients : You probably have most of this in your pantry right now. The bourbon is the only “special” ingredient, and honestly, you can skip it if you want (though I wouldn’t recommend it).
• Perfect for Late Summer : This is the dessert you make when peaches are at their peak and you’re trying to hold onto the season just a little longer. It works for Labor Day parties, family dinners, or just because.
• Crowd-Pleaser : I’ve served this to kids, grandparents, and everyone in between. The bourbon bakes off mostly, leaving just a warm, subtle flavor that even non-booze people tend to love. The peaches and brown sugar do the heavy lifting.
• Next-Level Comfort Food : The texture is what gets me every time. The cake is tender and buttery, the peaches get soft and almost jammy on top, and the glaze seeps into every little crevice. It’s like cobbler and cake had a beautiful baby.

What makes this different from other peach cakes? It’s the bourbon, sure, but it’s also the technique. I brown the butter first—just a quick step that adds this nutty, toasty flavor that pairs perfectly with the sweet peaches. And instead of just tossing the peaches on top, I give them a quick toss with brown sugar and bourbon before layering them into the batter. It means every bite has that caramelized, boozy-sweet flavor, not just the top layer.

This recipe is the kind that makes you close your eyes after the first bite. It’s comfort food reimagined—easier than a traditional cobbler, more impressive than a plain cake, and exactly the kind of dessert that makes summer feel like it’s not quite over yet.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, and the ones that aren’t are easy to find at any grocery store. Here’s what you’ll need:

For the Cake

• Unsalted butter, 1 cup (2 sticks) — I use Kerrygold here because the higher fat content makes for a richer cake. You’ll brown it first, so don’t skip that step.
• Light brown sugar, 1 ½ cups, packed — This adds moisture and that deep, caramel-like sweetness that pairs so well with bourbon and peaches.
• Granulated sugar, ½ cup — Just enough to balance the molasses notes of the brown sugar.
• Large eggs, 3, room temperature — Room temperature eggs incorporate better into the batter, giving you a lighter, fluffier cake. Set them out about 30 minutes before you start.
• Vanilla extract, 2 teaspoons — Pure vanilla, not imitation. It makes a difference here.
• All-purpose flour, 2 ½ cups — Spoon and level it into your measuring cup. Scooping directly can pack the flour and make the cake dense.
• Baking powder, 1 ½ teaspoons
• Baking soda, ½ teaspoon
• Salt, ½ teaspoon — I prefer fine sea salt for baking.
• Buttermilk, 1 cup, room temperature — The acidity in buttermilk tenderizes the gluten, making for a softer cake. No buttermilk? Add 1 tablespoon of lemon juice or vinegar to regular milk and let it sit for 5 minutes.
• Bourbon, ¼ cup — Use one you’d actually drink. I like Bulleit or Maker’s Mark for this. The bourbon flavor mellows as it bakes, so don’t worry about it being too strong.

For the Peach Layer

• Fresh peaches, 4 medium (about 2 cups sliced) — Ripe but still firm enough to hold their shape. If peaches aren’t in season, frozen sliced peaches work too—just thaw and pat them dry first.
• Light brown sugar, 2 tablespoons
• Bourbon, 1 tablespoon
• Cornstarch, 1 teaspoon — This helps thicken the juices as the peaches bake so you don’t end up with a soggy cake.

For the Glaze

• Powdered sugar, 1 ½ cups, sifted — Sifting prevents lumps. Trust me on this one.
• Bourbon, 2 tablespoons — You can substitute milk or cream if you want a non-alcoholic version, but the bourbon really makes this glaze sing.
• Vanilla extract, ½ teaspoon
• Milk, 1-2 tablespoons, as needed — Add slowly until you reach your desired consistency.

I recommend using fresh, in-season peaches for the best flavor. If you can smell them before you buy them, that’s a good sign. For the bourbon, don’t use anything too fancy—a mid-range bottle works perfectly. And if you’re out of buttermilk, the quick substitute works like a charm.

Equipment Needed

You don’t need a ton of fancy equipment for this recipe, which is part of why I love it. Here’s what you’ll need:

• Half-sheet pan (18×13 inches) — This is the standard size for sheet cakes. If you don’t have one, a 9×13 baking dish works, but you’ll need to increase the baking time by about 10-15 minutes. I prefer the sheet pan because it gives you more surface area for that perfect peach-to-cake ratio.
• Mixing bowls — One large, one medium, and one small. Nothing fancy needed.
• Whisk — For combining dry ingredients and for the glaze.
• Hand mixer or stand mixer — You can do this by hand if you’ve got some arm strength, but a mixer makes creaming the butter and sugar much easier. I use my KitchenAid for this.
• Spatula — A rubber spatula for folding in the peaches and scraping down the bowl.
• Small saucepan — For browning the butter. A light-colored pan is best so you can see the butter change color.
• Parchment paper — Line your sheet pan with this for easy removal. Don’t skip it—trust me, you don’t want to fight with stuck-on cake.
• Cooling rack — For letting the cake cool before glazing. If you don’t have one, you can use the stovetop grates (just make sure they’re clean).
• Measuring cups and spoons — Standard set for dry and liquid ingredients.

If you’re new to sheet cakes, I highly recommend picking up a good quality half-sheet pan. They’re inexpensive and incredibly versatile—I use mine for everything from cookies to roasting vegetables. And if you’re looking for a budget-friendly option, the ones from restaurant supply stores are usually the best value.

Preparation Method

Alright, let’s get baking. This recipe has a few steps, but I promise it’s straightforward. Take your time with the first part—browning the butter—and the rest will fly by.

Step 1: Brown the Butter

Add the 1 cup of unsalted butter to a small saucepan over medium heat. Let it melt completely, then continue cooking, swirling the pan occasionally. The butter will start to foam, then bubble, then turn golden. You’ll see little brown specks forming at the bottom—that’s the milk solids toasting. Keep a close eye on it; once it turns a deep amber color and smells nutty, pull it off the heat immediately. This usually takes about 5-7 minutes. Pour the browned butter into a large mixing bowl to cool slightly while you prep the other ingredients. Don’t leave it in the hot pan or it will continue to cook and potentially burn.

Step 2: Prepare the Peaches

While the butter cools, slice your peaches. I like to cut them into wedges about ½ inch thick—not too thin, or they’ll disappear into the cake, and not too thick, or they won’t soften enough. Toss the peach slices with 2 tablespoons of brown sugar, 1 tablespoon of bourbon, and 1 teaspoon of cornstarch in a medium bowl. Let them sit while you make the batter. This gives the sugar time to draw out some of the peach juices and the cornstarch time to start working.

Step 3: Make the Cake Batter

Preheat your oven to 350°F (175°C). Line your half-sheet pan with parchment paper, letting it overhang on the long sides for easy lifting later.

To the bowl with the cooled browned butter, add 1 ½ cups packed light brown sugar and ½ cup granulated sugar. Beat with a hand mixer or stand mixer on medium speed until well combined, about 2 minutes. The mixture should look like wet sand. Add the 3 room-temperature eggs one at a time, beating well after each addition. Scrape down the sides of the bowl. Add 2 teaspoons of vanilla extract and ¼ cup of bourbon, then beat until smooth.

In a separate medium bowl, whisk together 2 ½ cups all-purpose flour, 1 ½ teaspoons baking powder, ½ teaspoon baking soda, and ½ teaspoon salt. Add the dry ingredients to the wet mixture in three additions, alternating with the 1 cup of buttermilk. Start and end with the flour mixture. Mix on low speed just until combined after each addition. Overmixing at this stage will make the cake tough, so stop as soon as you don’t see any more streaks of flour. Fold in the peach mixture gently with a spatula, making sure the peaches are evenly distributed throughout the batter.

Step 4: Bake the Cake

Pour the batter into your prepared sheet pan and spread it evenly with your spatula. It will be thick, so take your time. Bake for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean or with just a few moist crumbs. The edges should be pulling away from the sides of the pan slightly. If your cake is browning too quickly on top, tent it loosely with foil for the last 5-10 minutes. Let the cake cool in the pan on a wire rack for about 15 minutes, then use the parchment paper to lift it out and transfer it to the rack to cool completely.

Step 5: Make the Glaze

Once the cake is completely cool (this is important—warm cake will just absorb the glaze), make the glaze. In a small bowl, whisk together 1 ½ cups sifted powdered sugar, 2 tablespoons bourbon, and ½ teaspoon vanilla extract. Add milk 1 tablespoon at a time, whisking after each addition, until the glaze is thick but pourable. You want it to be thick enough that it coats the back of a spoon but thin enough to drizzle. Drizzle the glaze over the cooled cake using a spoon or a piping bag with the tip snipped off. Let the glaze set for about 10-15 minutes before slicing.

Cooking Tips & Techniques

I’ve made this cake enough times to learn a few things the hard way. Here are my best tips for getting it right every time:

Don’t rush the butter browning. I know it’s tempting to crank up the heat and get it over with, but low and slow is the way to go. Medium heat, constant attention, and patience. The first time I tried this, I walked away for “just a second” and ended up with burnt butter that smelled like a campfire. Not ideal. Watch for that nutty aroma—that’s your cue.

Room temperature ingredients matter. I cannot stress this enough. Cold eggs and cold buttermilk will seize up your browned butter and give you a dense, uneven cake. Set everything out on the counter at least 30 minutes before you start. If you forget, you can place your eggs in a bowl of warm water for 5 minutes and microwave your buttermilk for about 15 seconds.

Use the right peaches. You want peaches that are ripe but still firm. Mushy peaches will break down too much and make the cake soggy. If your peaches are on the firmer side, that’s actually perfect—they’ll soften just enough in the oven while still holding their shape. And please, for the love of good baking, don’t use canned peaches in syrup. They’re too soft and too sweet, and they’ll throw off the whole balance.

Let the cake cool completely before glazing. I know it’s hard to wait, especially when your kitchen smells amazing. But if you pour that glaze on a warm cake, it’ll soak right in and disappear. You’ll end up with a barely sweet cake instead of a beautifully glazed one. Give it at least an hour to cool on the rack.

Test for doneness properly. Because this is a sheet cake, it bakes relatively quickly. Start checking at the 22-minute mark. Insert a toothpick into the center—if it comes out clean, you’re done. If there’s wet batter, give it another 3-5 minutes. The top should be golden and the edges should be just starting to pull away from the pan.

Multitask like a pro. While the butter is browning, slice your peaches. While the cake is baking, make the glaze. While the cake is cooling, clean up your kitchen. This recipe is forgiving enough that you can work at your own pace, but a little planning goes a long way.

Variations & Adaptations

One of the best things about this cake is how adaptable it is. Here are some variations I’ve tried and loved:

Bourbon-Free Version — If you’re serving kids or avoiding alcohol, simply replace the bourbon in the cake and glaze with an equal amount of milk or apple cider. You’ll lose that warm, boozy depth, but you’ll still have a fantastic peach cobbler cake. For the glaze, use milk and add an extra ½ teaspoon of vanilla extract to make up for the missing flavor.

Gluten-Free Adaptation — I’ve made this with a 1:1 gluten-free baking flour blend (like King Arthur’s or Bob’s Red Mill) and it worked beautifully. The texture is slightly more tender and a bit more crumbly, but the flavor is spot on. Just be careful not to overmix the batter, as gluten-free flours can get gummy if overworked.

Seasonal Fruit Swaps — This recipe works beautifully with other stone fruits. Try sliced nectarines, plums, or even apricots when they’re in season. In the fall, you can swap in thinly sliced apples or firm pears—just toss them with a little extra brown sugar and cinnamon. If you’re using frozen fruit, don’t thaw it first; just add it frozen and increase the baking time by about 5 minutes.

Spiced-Up Version — Add 1 teaspoon of cinnamon and ½ teaspoon of nutmeg to the dry ingredients for a warmer, cozier flavor profile. A pinch of cardamom works beautifully too, especially if you’re using plums instead of peaches. I tried this once during a chilly September evening and it was exactly what I needed.

Bourbon Peach Cobbler Sheet Cake with a Crunchy Topping — Before baking, sprinkle the top of the batter with a mixture of 2 tablespoons of coarse sugar (like turbinado) and ½ cup of chopped pecans. It adds a lovely crunch that contrasts with the soft cake and peaches. This is my husband’s favorite version.

If you’re looking for another dessert that captures that same late-summer feeling, I highly recommend checking out this creamy grilled peach burrata salad. It’s a different kind of sweet, but it has that same peachy, warm-weather magic.

Serving & Storage Suggestions

This cake is best served at room temperature, which makes it perfect for parties and potlucks. The glaze will be set but still soft, and the cake will be tender and moist. If you want to go the extra mile, serve each slice with a scoop of vanilla bean ice cream or a dollop of lightly sweetened whipped cream. The cold creaminess against the warm, boozy cake is absolutely heavenly.

For presentation, I like to dust the top with a little cinnamon or nutmeg before serving, and maybe add a few fresh peach slices on the side. It’s simple but looks impressive. This cake also pairs wonderfully with a cup of hot coffee or a glass of iced tea.

Storage Instructions: Store leftover cake in an airtight container at room temperature for up to 2 days. After that, transfer it to the refrigerator for up to 5 days. The glaze will soften slightly in the fridge, but the flavor will still be great. If you’re storing it for more than a day, I recommend placing a piece of parchment paper between the cake and the lid to prevent the glaze from sticking.

Freezing Instructions: This cake freezes beautifully. Let it cool completely without the glaze, then wrap it tightly in plastic wrap and then a layer of aluminum foil. Freeze for up to 3 months. When you’re ready to serve, thaw it in the refrigerator overnight, bring it to room temperature, and then make the glaze and drizzle it on fresh. I’ve done this several times when I wanted to get ahead on dessert for a gathering, and it works like a charm.

Reheating Tips: If you prefer your cake warm, pop individual slices in the microwave for about 15-20 seconds. For a larger portion, warm it in a 300°F oven for about 10 minutes. The flavors actually deepen slightly after a day or two, so don’t be afraid of leftovers. The bourbon and peach flavors meld together even more as the cake sits.

If you’re planning a game day spread or a casual get-together, this cake pairs beautifully with savory dishes. It would be a fantastic sweet ending to a meal featuring something like these grilled garlic butter shrimp skewers or alongside a bowl of slow cooker ham and bean soup for a cozy fall dinner.

Peaches are a good source of vitamins A and C, as well as fiber and antioxidants. The bourbon, in moderation, has been linked to some heart health benefits, though let’s be honest—we’re here for the flavor, not the health claims. The buttermilk adds a touch of calcium and probiotics, and the eggs provide high-quality protein. All that to say, this is a dessert, and it’s meant to be enjoyed. Balance it with a healthy meal and a good walk, and you’re golden.

Conclusion

This bourbon peach cobbler sheet cake with glaze has become my go-to for late summer gatherings, and I think it’ll become yours too. It’s the kind of dessert that feels special without being fussy—the kind you can make on a Wednesday night just because you have peaches that need using and a little bourbon left in the bottle. The browned butter adds depth, the peaches bring that sweet-tart summer flavor, and the bourbon glaze ties it all together in the most beautiful way.

I love that this recipe is forgiving. If your peaches are a little more or less ripe, it still works. If you forget to set your eggs out, you can still make it work. It’s a recipe that wants to be made, not one that fights you every step of the way. And that’s exactly the kind of recipe I want to share with you.

Frequently Asked Questions

Can I use frozen peaches instead of fresh?

Absolutely. Frozen peaches work well in this recipe, especially when fresh peaches aren’t in season. Just thaw them first and pat them dry with paper towels to remove excess moisture. If you add them frozen, you’ll need to increase the baking time by about 5-8 minutes, and the cake might be slightly more moist.

Can I make this cake without bourbon?

Yes, you can. Replace the bourbon in the cake with an equal amount of milk, apple cider, or even water. For the glaze, use milk instead of bourbon and add an extra ½ teaspoon of vanilla extract. The cake will still be delicious—it just won’t have that warm, boozy depth that bourbon adds.

How do I know when the butter is properly browned?

You’re looking for a deep amber color and a nutty aroma. The butter will go from melted to foamy to golden, and then you’ll see brown specks forming at the bottom of the pan. As soon as it smells nutty and looks like the color of light caramel, pull it off the heat. Don’t wait until it’s dark brown, or it will taste burnt.

Can I make this cake ahead of time?

Yes, and it actually gets better after a day or two as the flavors meld. Bake the cake, let it cool completely, and store it in an airtight container at room temperature. Make the glaze and drizzle it on just before serving. You can also freeze the unglazed cake for up to 3 months (see storage instructions above).

Why did my cake come out dense?

Dense cake usually comes from overmixing the batter or using cold ingredients. Mix just until the flour is incorporated—no more. Also, make sure your eggs and buttermilk are at room temperature before you start. Cold ingredients can cause the batter to seize up and result in a heavy, dense texture.
