How to Make It

Let’s dive into the steps to create this delightful coffee cake.

Preheat Oven

Preheat oven to 350 degrees. Prepare a 9-inch cake pan with a circle of parchment paper in the bottom and grease the sides.

Prepare Streusel

Combine flour, brown sugar, cinnamon, melted butter, and salt in a medium bowl. Mix with a fork until crumbly. Set aside.

Prepare Dry Ingredients

Combine flour, baking powder, and salt in another medium bowl and set aside.

Cream Butter and Sugar

Add sugar and butter to a large mixing bowl. Beat together until light in color and fluffy, about 3-4 minutes.

Mix in Sour Cream

Add sour cream and mix just until well combined.

Incorporate Milk

Add milk and mix just until well combined.

Add Egg and Vanilla

Add egg and vanilla extract, mixing just until well combined.

Combine Dry and Wet Ingredients

Add dry ingredients to the batter and mix until just combined.

Spread First Layer

Spread half of the cake batter into the bottom of the prepared cake pan. The batter will be thick and the layer will be thin.

Add Streusel and Blueberries

Sprinkle about half of the streusel mixture evenly over the cake batter, then add half of the blueberries.

Add Remaining Batter

Drop spoonfuls of the remaining cake batter over the streusel and blueberries. Carefully spread into an even layer, which will also be thin.

Top the Cake

Sprinkle the remaining streusel and blueberries over the top of the cake batter.

Bake

Bake for 32-38 minutes, or until a toothpick inserted comes out with a few crumbs.

Cool the Cake

Remove cake from oven and allow to cool in the pan for about 20 minutes, then transfer to a cooling rack to finish cooling.

Make the Glaze

In a small bowl, combine powdered sugar, milk, and vanilla extract. Whisk until smooth, adjusting milk or sugar as needed.

Drizzle and Serve

Drizzle the glaze over the coffee cake and sprinkle a few additional blueberries on top. Serve and enjoy!

Tips for Best Results

• Ensure your butter is softened to room temperature for easier creaming.
