Fruit additions like blueberries or apples

How to Make Sour Cream Blueberry Coffee Cake

Follow these simple steps for the perfect coffee cake.

Step 1: Prepare the Oven and Pan

Preheat your oven to 350°F (175°C).

Grease a 9-inch square baking pan or line it with parchment paper to prevent sticking.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together:

Flour
Baking powder
Baking soda

Salt

Set the mixture aside.

Step 3: Cream Butter and Sugar

In a large mixing bowl, beat the softened butter and sugar together until light and fluffy. This usually takes about 2–3 minutes.

Creaming properly helps create a soft and tender cake texture.

Step 4: Add Eggs, Sour Cream, and Vanilla

Beat in the eggs one at a time.

Then mix in:

Sour cream
Vanilla extract

The batter will become thick and creamy.

Step 5: Combine Wet and Dry Ingredients

Gradually add the dry ingredients to the wet mixture and stir until just combined.

Avoid overmixing to keep the cake soft.

Step 6: Fold in the Blueberries

Gently fold the blueberries into the batter using a spatula.

Tip: Toss blueberries with 1 tablespoon of flour before mixing to prevent them from sinking.

Step 7: Prepare the Crumb Topping

In a small bowl, combine:

Flour

Brown sugar
Cinnamon

Pour in melted butter and mix until crumbly.

Step 8: Assemble the Cake

Spread the batter evenly into the prepared pan.

Sprinkle the crumb topping evenly across the surface.

Step 9: Bake

Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.

The top should be golden brown and slightly crisp.

Step 10: Cool and Serve

Allow the cake to cool for about 15 minutes before slicing.

Serve warm or at room temperature.

Tips for the Best Blueberry Coffee Cake

Follow these baking tips for perfect results every time.

Use Room Temperature Ingredients

Overmixing can make the cake dense instead of soft.

Use Fresh or Frozen Blueberries

Both work well. If using frozen berries, do not thaw them first.

Check for Doneness

Insert a toothpick in the center. If it comes out clean, the cake is ready.
