Why This Blueberry Sour Cream Coffee Cake Recipe Stands Out
What makes this blueberry sour cream coffee cake truly special? It’s the harmonious blend of flavors and textures. The sour cream not only contributes to the cake’s incredible moisture but also adds a subtle tang that beautifully complements the sweet blueberries. Unlike some denser coffee cakes, this one boasts a light and airy crumb that practically melts in your mouth.
- Moisture Retention: Sour cream is the secret ingredient for a cake that stays moist for days.
- Flavor Balance: The slight tanginess of the sour cream enhances the sweetness of the blueberries and sugar.
- Tender Crumb: Sour cream’s acidity helps to break down gluten, resulting in a more delicate texture.

Ingredients for Blueberry Sour Cream Coffee Cake
Cake Batter
- 2 cups all-purpose flour
- 1 tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt

- 1 cup granulated sugar
- 2 large eggs
- 1 tsp vanilla extract
- 1 cup sour cream

Step-by-Step: How to Make Blueberry Sour Cream Coffee Cake
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease a 9-inch springform pan or line it with parchment paper.
- Make the Crumb Topping: In a small bowl, combine flour, brown sugar, granulated sugar, and cinnamon. Stir in melted butter until crumbly. Set aside.
- Mix Dry Ingredients: In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
- Cream Butter and Sugar: In a large bowl, beat butter and sugar until light and fluffy (about 2-3 minutes). Add eggs one at a time, then mix in vanilla extract.
- Combine Wet and Dry: Gradually add dry ingredients to the butter mixture, alternating with sour cream. Start and end with the dry ingredients. Mix until just combined.
- Fold in Blueberries: Gently fold in blueberries to avoid crushing them.
- Assemble: Spread the batter evenly in the prepared pan. Sprinkle the crumb topping over the batter.
- Bake: Bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
- Cool and Serve: Let the cake cool in the pan for 10 minutes, then transfer to a wire rack. Serve warm or at room temperature.
