A Perfect Balance of Moistness and Flavor
Sour Cream Blueberry Coffee Cake stands out because of its incredibly moist texture. The sour cream keeps the cake soft and tender while adding a subtle tang that enhances the overall flavor.

This flexibility makes it a staple recipe for both everyday baking and special occasions.
Ingredients and Their Role
The Cake Batter
Butter provides richness and helps create a tender crumb. Sugar sweetens the cake while contributing to its soft texture.
Eggs add structure and help bind the ingredients together. Vanilla extract enhances the flavor with a warm, sweet note.
Sour cream is the key ingredient, adding moisture and a slight tang that makes the cake unique.
Flour forms the base, while baking powder and baking soda help the cake rise. Salt balances the sweetness and enhances the overall flavor.
Blueberries bring bursts of freshness and natural sweetness to the cake.
The Streusel Topping
Brown sugar adds a deep, caramel-like sweetness. Flour helps create the crumbly texture, while cinnamon adds warmth and spice.
Cold butter is worked into the mixture to form a crumbly topping that becomes golden and slightly crisp when baked.
This topping adds both flavor and texture, making the cake even more enjoyable.
Step-by-Step Instructions
Preparing the Batter
Start by preheating your oven to 350°F (175°C) and greasing a baking pan.
In a bowl, cream together butter and sugar until light and fluffy. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract and sour cream.
In a separate bowl, whisk together flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Gently fold in the blueberries, being careful not to overmix.
Assembling and Baking
Pour the batter into the prepared pan and spread evenly.
In a separate bowl, mix brown sugar, flour, and cinnamon. Cut in the cold butter until the mixture becomes crumbly.
Sprinkle the streusel evenly over the batter.
Bake for 40–50 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool slightly before slicing and serving.

Tips for Best Results
Use room-temperature ingredients for a smoother batter and even baking.
