The Story Behind Rhubarb Sour Cream Coffee Cake
If you’ve ever wondered about the origins of coffee cake, it’s believed to have European roots, where it was often served alongside coffee or tea. Over time, the concept traveled to America and evolved into the sweet, streusel-topped varieties we know and love today. Adding rhubarb into the mix is a delightful twist that brings a hint of tartness to balance out the sweetness.
Rhubarb itself has a rich history, dating back thousands of years to Asia. While it was initially used for medicinal purposes, it eventually found its way into the kitchen. In places like the Midwest, rhubarb is lovingly referred to as the “pie plant” because of its popularity in desserts. For me, rhubarb always reminds me of spring and summer, when its vibrant red stalks are at their peak.
This recipe holds a special place in my heart because I first made it with my grandmother. She had a knack for turning simple, seasonal ingredients into something extraordinary. Every time I bake this coffee cake, it takes me back to her cozy kitchen, filled with the aroma of cinnamon and sugar. It’s a tradition I’m proud to carry on.
Ingredients for Rhubarb Sour Cream Coffee Cake
Let’s talk about what makes this coffee cake so irresistible. Each ingredient plays a key role in creating the perfect texture and flavor. Here’s a breakdown:
- Rhubarb: The star of the show! Look for firm, bright red stalks for the best flavor. If rhubarb isn’t in season, frozen rhubarb works just as well—just be sure to thaw and drain it first.
- Sour Cream: Adds moisture and a subtle tang to the cake. If you need a substitution, plain Greek yogurt is a great alternative.
- All-Purpose Flour: The base of the cake. You can use a 1:1 gluten-free flour blend if needed.
- Granulated Sugar: Sweetens the cake and balances the tartness of the rhubarb.
- Brown Sugar: Used in the streusel for a deeper, caramel-like sweetness.
- Butter: Adds richness to both the cake and the streusel topping. Unsalted is best so you can control the saltiness.
- Eggs: Provide structure and help the cake rise.
- Baking Powder & Baking Soda: Essential for a light, fluffy texture.
- Cinnamon: Adds warmth and depth to the streusel topping.
- Vanilla Extract: Enhances the overall flavor of the cake.
If you’re feeling adventurous, you can even toss in some chopped nuts or swap out part of the rhubarb for strawberries. The possibilities are endless!
Equipment Needed
You don’t need a ton of fancy equipment to make this Rhubarb Sour Cream Coffee Cake. Here’s what you’ll want to have on hand:
- A 9×13-inch baking pan (or two 8-inch square pans if you prefer a smaller batch).
- A hand or stand mixer for creaming the butter and sugar.
- Mixing bowls for the batter and streusel.
- A spatula for folding in the rhubarb.
- Measuring cups and spoons to get those proportions just right.
If you don’t have a mixer, don’t worry—you can cream the butter and sugar by hand with a bit of elbow grease. And if you’re short on baking pans, a springform pan works beautifully, too.
How to Make Rhubarb Sour Cream Coffee Cake
- Preheat the oven: Set your oven to 350°F (175°C) and grease your baking pan.
- Prepare the streusel: In a small bowl, combine 1 cup (200g) of brown sugar, 1/2 cup (115g) of butter (cold and cubed), 1 cup (120g) of flour, and 1 teaspoon of cinnamon. Use a fork or pastry cutter to create a crumbly mixture. Set aside.
- Mix the dry ingredients: In a medium bowl, whisk together 2 cups (240g) of flour, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt.
- Cream the butter and sugar: In a large bowl, beat 1/2 cup (115g) of softened butter with 1 cup (200g) of granulated sugar until light and fluffy, about 2-3 minutes.
- Add eggs and vanilla: Beat in 2 large eggs, one at a time, followed by 2 teaspoons of vanilla extract.
- Incorporate the sour cream: Mix in 1 cup (240g) of sour cream until smooth.
- Combine the wet and dry ingredients: Gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix.
- Fold in the rhubarb: Gently fold in 2 cups (250g) of chopped rhubarb with a spatula.
- Assemble the cake: Spread half the batter into the prepared pan, sprinkle with half the streusel, then add the remaining batter and top with the rest of the streusel.
- Bake: Bake for 40-45 minutes or until a toothpick inserted into the center comes out clean.
- Cool: Allow the cake to cool in the pan for at least 20 minutes before slicing.
Cooking Tips & Techniques
Here are some insider tips to ensure your coffee cake turns out perfectly every time:
- Don’t overmix the batter! Overmixing can lead to a dense cake rather than a fluffy one.
- Use cold butter for the streusel. It helps create those irresistible crumbs on top.
- Check your rhubarb—it’s crucial to remove all the leaves, as they’re toxic.
- For an even bake, rotate the pan halfway through cooking.
- If you’re unsure about doneness, err on the side of slightly underdone. The cake will continue to cook as it cools.
Variations & Adaptations
This coffee cake is wonderfully versatile. Here are a few ideas to make it your own:
- Gluten-Free: Swap out the all-purpose flour for a gluten-free baking blend.
- Dairy-Free: Use a plant-based yogurt instead of sour cream and vegan butter for the streusel.
- Berry Twist: Replace half the rhubarb with fresh or frozen strawberries for a sweeter flavor.
- Nuts: Add 1/2 cup (60g) of chopped walnuts or pecans to the streusel for extra crunch.
One time, I even tried adding a touch of lemon zest to the batter—it gave the cake a bright, citrusy kick!
