How to Make Moist Blueberry Sour Cream Coffee Cake (Step-by-Step)
Step 1: Prep the Pan and Oven
- Preheat your oven to 350°F (175°C).
- Grease and flour a 9-inch square baking pan, or line it with parchment paper.
Step 2: Cream Butter and Sugar
- In a large mixing bowl, beat the softened butter and sugar until light and fluffy.
- This creates a light base that supports the moist texture.
Step 3: Add Eggs, Sour Cream, and Vanilla
- Beat in the eggs one at a time, mixing well after each.
- Stir in the sour cream and vanilla extract. The batter should be creamy and smooth.
Step 4: Mix Dry Ingredients
- In another bowl, whisk together the flour, baking powder, baking soda, and salt.
- Gradually add this to the wet mixture, mixing only until just combined.
Step 5: Fold in Blueberries
- Gently fold in the blueberries. Don’t overmix—this can lead to dense cake and smashed berries.
- For technique visuals, see Pinterest’s how-to coffee cake tutorials.
Step 6: Make the Streusel Topping
- In a small bowl, combine brown sugar, flour, and cinnamon.
- Cut in the cold butter using a fork or pastry cutter until the mixture resembles coarse crumbs.
Step 7: Assemble and Bake
- Pour the batter into the prepared pan and spread evenly.
- Sprinkle the streusel topping over the batter.
- Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.
- Let cool in the pan for at least 15 minutes before slicing.
