Sour Cream Blueberry Coffee Cake Recipe Details:
- Preparation time: 20 minutes
- Baking time: 40-45 minutes
- Servings: 9-12
- Equipment: 9-inch square baking pan, mixing bowls
Ingredients:
For the Cake Base:
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- ½ cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 cup sour cream
- 1 teaspoon vanilla extract
- 1 and ½ cups fresh or frozen blueberries
For the Streusel Topping:
- ½ cup brown sugar
- ½ cup all-purpose flour
- 1 teaspoon ground cinnamon
- ¼ cup cold butter, cubed
Optional Glaze:
- ½ cup powdered sugar
- 1 to 2 tablespoons milk
- ½ teaspoon vanilla extract
Directions:
- Preheat your oven to 350°F. Carefully grease and flour a 9-inch square pan, or line with parchment paper for easy removal.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- In a large mixing bowl, cream the butter and sugar together until light and fluffy. This should take about 3-4 minutes.
- Add eggs one at a time, beating well after each addition. Mix in the sour cream and vanilla extract until the mixture becomes smooth.
- Gradually add the dry ingredients to the wet mixture. Stir just until combined – do not overmix.
- Gently fold in the blueberries, being careful not to crush them. The batter will be thick.
- Spread the batter evenly into the prepared pan.
- For the streusel topping, mix the brown sugar, flour, and cinnamon in a bowl.
- Cut in the cold butter using a pastry cutter or fork until the mixture becomes crumbly.
- Sprinkle the streusel topping evenly over the cake batter.
- Bake for 40 to 45 minutes. To check for doneness, insert a toothpick into the center – it should come out clean or with just a few moist crumbs.
- If using the optional glaze, whisk together the powdered sugar, milk, and vanilla in a small bowl.
