Ingredients
Scale
Dry Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
Wet Ingredients
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs, room temperature
- 1 teaspoon vanilla extract
- 1 cup full-fat sour cream
Fruits
- 2 cups fresh blueberries, tossed with 1 tablespoon flour
Topping
- 1/2 cup brown sugar
- 1/2 cup chopped pecans (optional)
- 1 teaspoon ground cinnamon
Instructions
- Preheat and prepare pan: Preheat your oven to 350°F (175°C). Grease a 9-inch square baking pan or a springform pan to prevent sticking.
- Mix dry ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until evenly combined.
- Cream butter and sugar: In a large mixing bowl, beat the softened unsalted butter with the granulated sugar until the mixture becomes light and fluffy, typically 3-4 minutes with a mixer.
- Add eggs and vanilla: Add the eggs one at a time to the creamed mixture, mixing well after each addition to ensure a smooth batter. Stir in the vanilla extract for flavor.
- Incorporate sour cream: Mix in the full-fat sour cream until the batter is smooth and well blended.
- Combine dry and wet: Gradually add the dry ingredient mixture to the wet ingredients, folding gently and mixing just until combined to avoid overworking the batter.
- Fold in blueberries: Carefully fold in the blueberries that have been tossed in flour to prevent them from sinking during baking.
- Prepare topping: In a small bowl, combine the brown sugar, chopped pecans (if using), and ground cinnamon creating a streusel mix.
- Layer the batter and topping: Spread half of the batter evenly into the prepared pan. Sprinkle half of the cinnamon-pecan topping over the batter layer. Spread the remaining batter on top, then finish by sprinkling the rest of the topping evenly over the surface.
- Bake the cake: Bake in the preheated oven for 45 to 55 minutes, or until a toothpick inserted into the center comes out clean. Baking times can vary depending on your oven.
- Cool and serve: Allow the coffee cake to cool in the pan for at least 20 minutes before slicing and serving to let it set properly and make slicing easier.
Notes
- Tossing the blueberries in flour prevents them from sinking to the bottom of the cake during baking.
- You can substitute fresh blueberries with frozen ones; do not thaw before using but increase the baking time slightly to compensate.
- Store leftovers covered at room temperature for up to 2 days or refrigerate to keep fresh longer.
