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.
