How to Make Sour Cream Rhubarb Coffee Cake
-
Preheat the oven to 350°F (175°C) and prep a 9-inch square baking pan by greasing and flouring it. This will ensure your cake releases easily after baking.
-
Combine the sour cream and baking soda in a small bowl; set aside. You’ll notice it fizzling, which means it’s activating for a light texture.
-
Cream softened butter and granulated sugar in a large bowl until fluffy and pale, about 3-4 minutes. This step adds air to your batter for a tender crumb!
-
Incorporate the egg and vanilla extract into the butter mixture, blending until smooth. This adds richness and enhances the cake’s flavor profile.
-
Mix the fizzling sour cream concoction into the batter until well combined. This secret ingredient keeps the cake wonderfully moist!
-
Fold in flour and salt gradually, mixing gently to avoid overmixing. This is crucial for keeping your cake tender and light.

Gently add diced rhubarb to the batter, folding it in for even distribution. The beautiful tartness of rhubarb makes each bite refreshing!

Expert Tips for Sour Cream Rhubarb Coffee Cake
- Mind the Mixing: Avoid overmixing the batter once the flour is added. This ensures your sour cream rhubarb coffee cake remains light and tender.
- Check for Doneness: Bake until only a few crumbs stick to your toothpick. Underbaking slightly can help keep the cake moist and prevents it from drying out.
- Prep Your Rhubarb: Wash, trim, and dice the rhubarb uniformly for even distribution in the cake. Uneven pieces can lead to pockets of tartness!
- Warm Up Your Ingredients: Use room-temperature butter and eggs; they incorporate better, leading to a fluffier cake.
- Substitution Tips: Feel free to swap rhubarb with strawberries or mixed berries for a different flavor. This flexibility makes your sour cream rhubarb coffee cake suitable for various tastes!
Make Ahead Options
These Sour Cream Rhubarb Coffee Cakes are perfect for meal prep enthusiasts! You can prep the batter up to 24 hours in advance by combining all the ingredients except for the rhubarb, which should be added right before baking to prevent it from becoming too mushy. Simply refrigerate the batter in an airtight container and then pour it into the prepared pan along with diced rhubarb when you’re ready to bake. If you prefer, you can also prepare the topping ahead of time and store it separately in the fridge for up to 3 days. This way, you can enjoy a freshly baked cake with minimal effort, perfect for busy mornings or unexpected guests!
