The Story Behind Plum Upside-Down Cake

Upside-down cakes have been around for centuries, with their origins tracing back to the early 1900s when cast iron skillets were a kitchen staple. Pineapple Upside-Down Cake may be the most famous variant, but using plums instead brings a unique twist that feels perfect for late summer and early fall.

Plums are one of those fruits that just scream “seasonal treat.” Their vibrant hues and juicy flesh make them ideal for desserts. I first discovered the magic of plum upside-down cake during a family visit to a farmers’ market. The aroma of ripe plums inspired me to create something memorable. Over the years, I’ve tweaked the recipe, experimenting with different spices and techniques to get it just right.

This cake is perfect for showcasing the beauty of plums. It’s rustic yet elegant, sweet yet tangy—a dessert that feels cozy but also sophisticated enough to impress. Plus, preparing it is almost as fun as eating it. Watching the caramel bubble and the plums settle into the buttery syrup is pure kitchen magic.

Ingredient Breakdown

Let’s dive into the ingredients that make this Plum Upside-Down Cake so irresistible. Each component plays a crucial role in flavor, texture, and appearance. Here’s what you’ll need:

• Plums: The star of the show! Choose firm, ripe plums for the best results. Red or black plums work best for their vibrant color, but yellow plums can add a unique twist. If plums aren’t in season, apricots or peaches are great substitutes.
• Brown Sugar: This is what creates the caramelized topping. Dark brown sugar adds a deeper, molasses-like flavor, while light brown sugar gives a milder sweetness. Either works beautifully.
• Unsalted Butter: Butter not only helps create the caramel but also makes the cake rich and tender. Make sure it’s softened for the batter and melted for the topping.
• All-Purpose Flour: A sturdy base for the cake that’s easy to work with. For a gluten-free version, you can substitute a 1:1 gluten-free baking flour.
• Baking Powder: Essential for giving the cake its lift and fluffiness. Ensure your baking powder is fresh for the best results.
• Eggs: They bind the ingredients together and provide structure. Room-temperature eggs are best for smoother mixing.
• Milk: Adds moisture to the cake batter. Whole milk is ideal, but you can use almond or oat milk for a dairy-free option.
• Vanilla Extract: A splash of vanilla ties all the flavors together. Use pure vanilla extract for a warm, aromatic touch.

Optional additions include a sprinkle of cinnamon or cardamom in the caramel for a spiced twist. And don’t forget a pinch of salt—it balances the sweetness perfectly.

Equipment Needed

The beauty of this recipe is that it doesn’t require any fancy gadgets. Here’s what you’ll need:

• 9-inch Round Cake Pan: A sturdy pan is essential for flipping the cake without disaster! If you don’t have a round pan, a square one works too.
• Mixing Bowls: You’ll need at least two for separating the wet and dry ingredients.
• Whisk or Hand Mixer: A whisk works fine for the batter, but a hand mixer makes the process quicker.
• Spatula: For spreading the batter evenly.
• Knife: A sharp knife for slicing the plums into uniform wedges.

If you’re new to flipping cakes, I recommend placing a plate or platter slightly larger than your pan for an easy transfer. And don’t forget oven mitts—they’re your best friend when handling hot caramel.

Preparation Method

1. Preheat your oven: Set it to 350°F (175°C). Grease your cake pan generously with butter or non-stick spray.
2. Prepare the caramel: Melt 1/4 cup (55g) of unsalted butter in a small saucepan over medium heat. Stir in 1/2 cup (100g) of brown sugar until dissolved. Pour the caramel into your cake pan, spreading it evenly.
3. Slice the plums: Cut 4-5 plums into thin wedges. Arrange them in a decorative pattern over the caramel. Set aside.
4. Mix the dry ingredients: In a medium bowl, whisk together 1 1/2 cups (190g) of all-purpose flour, 1 1/2 teaspoons of baking powder, and a pinch of salt.
5. Combine the wet ingredients: In a large bowl, beat 1/2 cup (115g) of softened butter with 3/4 cup (150g) of granulated sugar until fluffy. Add 2 eggs, one at a time, and 1 teaspoon of vanilla extract.
6. Finish the batter: Gradually add the dry ingredients to the wet, alternating with 1/2 cup (120ml) of milk. Mix until smooth.
7. Assemble the cake: Pour the batter over the plums, smoothing the top with a spatula. Tap the pan gently to remove air bubbles.
8. Bake: Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean.
9. Cool and flip: Let the cake cool for 10 minutes. Run a knife around the edges, then place a plate on top and flip it over. Lift the pan gently to reveal the caramelized plums.

Cooking Tips & Techniques

Here are some insider tips to guarantee the perfect Plum Upside-Down Cake:

• Don’t rush the caramel: Let it simmer just until it thickens. If it’s too runny, the topping may seep into the cake.
• Test your plums: If they’re too ripe, they’ll release extra juice and make the caramel watery.
• Room-temperature ingredients: This ensures a smoother batter and better mixing.
• Be patient when flipping: Allow the cake to cool slightly to prevent breaking. Use a confident motion and a sturdy plate.

And if your caramel sticks to the pan? No worries—just scrape it out and drizzle it back over the cake. It’s all part of the fun!

Variations & Adaptations

This recipe is versatile! Here are some ideas to make it your own:

• Seasonal swaps: Try peaches, nectarines, or even apples when plums aren’t available.
• Dietary tweaks: Use almond flour for a nutty flavor or coconut milk for a dairy-free option.
• Spiced caramel: Add a dash of cinnamon or nutmeg to the brown sugar for a warm, autumn vibe.

Once, I added a handful of chopped walnuts to the caramel—it created a crunchy surprise that everyone loved!

Serving & Storage Suggestions

This cake shines at room temperature, but it’s equally delicious served warm with a scoop of vanilla ice cream or whipped cream. For beverages, coffee or a light dessert wine pairs beautifully.

To store, wrap the cake tightly and refrigerate for up to 3 days. You can also freeze slices for up to a month. Just reheat in the oven at 300°F (150°C) for 10 minutes to revive its fresh-baked flavor.
