Ingredients
Scale
Cake
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup sour cream
- 1 1/2 cups fresh or frozen blueberries (if frozen, do not thaw)
Streusel Topping
- 1/3 cup brown sugar
- 1/3 cup all-purpose flour
- 1/2 teaspoon cinnamon
- 3 tablespoons cold unsalted butter, cubed
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a 9-inch springform pan or a 9×9-inch baking dish thoroughly to prevent sticking.
- Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt, ensuring they are evenly combined for consistent baking.
- Cream Butter and Sugar: In a large bowl, use an electric mixer to beat the softened unsalted butter and granulated sugar together until the mixture is light, fluffy, and pale in color, which will help create a tender crumb.
- Add Eggs and Vanilla: Beat in the eggs one at a time, mixing well after each addition. Then stir in the vanilla extract to infuse the batter with aroma and flavor.
- Incorporate Sour Cream: Mix in the sour cream until the batter is smooth and creamy, which contributes moisture and tanginess to the cake.
- Combine Wet and Dry Ingredients: Gradually add the flour mixture to the wet ingredients, mixing gently just until the dry ingredients are incorporated to avoid overmixing and tough cake.
- Fold in Blueberries: Carefully fold in the blueberries to distribute them evenly without breaking them up, preserving bursts of fruit throughout the cake.
- Transfer Batter: Spread the batter evenly into the prepared pan, smoothing the surface with a spatula.
- Prepare Streusel Topping: In a small bowl, combine brown sugar, flour, and cinnamon. Cut in the cold cubed unsalted butter using a fork or fingers until the mixture resembles coarse crumbs.
- Top the Cake: Sprinkle the streusel topping evenly over the batter for a sweet, crunchy finish.
- Bake: Bake in the preheated oven for 45 to 50 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs attached.
- Cool and Serve: Allow the cake to cool in the pan for at least 15 minutes before slicing to let it set for cleaner cuts. Enjoy warm or at room temperature.
Notes
- For added texture, stir chopped nuts such as walnuts or pecans into the streusel topping before sprinkling it on the batter.
- You can drizzle the cooled cake with a simple powdered sugar glaze (powdered sugar mixed with milk and vanilla) for extra sweetness and decoration.
- Store the cake well covered at room temperature for 2 to 3 days or refrigerate for longer freshness.
