Ingredients
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter softened
- 1 cup sour cream
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 and 1/2 cups fresh blueberries or frozen, unthawed
Optional Streusel Topping:
- 1/4 cup brown sugar
- 1/4 cup all-purpose flour
- 2 tablespoons butter cold and cubed
- 1/2 teaspoon ground cinnamon
Instructions
Step 1: Preheat Your Oven
- Preheat your oven to 350°F (175°C). Grease a 9-inch square baking pan or line it with parchment paper for easy removal.
Step 2: Prepare the Dry Ingredients
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this mixture aside.
Step 3: Cream the Butter and Sugar
- In a large bowl, use an electric mixer to beat the softened butter and granulated sugar until the mixture is light and fluffy. This should take about 2-3 minutes.
Step 4: Add Wet Ingredients
- Beat in the eggs one at a time, then add the vanilla extract. After that, blend in the sour cream until everything is well combined.
Step 5: Combine Wet and Dry Mixtures
- Gradually add the dry ingredients to the wet mixture. Stir just until combined — do not overmix, as this can toughen your cake.
Step 6: Fold in the Blueberries
- Gently fold the blueberries into the batter. If you want to prevent them from sinking to the bottom, lightly toss them in a tablespoon of flour before folding.
Step 7: Make the Streusel Topping (Optional)
- In a small bowl, mix the brown sugar, flour, cinnamon, and cold butter with a fork or your fingers until crumbly.
Step 8: Assemble the Cake
- Spread half of the batter into the prepared pan. Sprinkle a little streusel if using. Add the remaining batter on top, then finish with the rest of the streusel topping.
Step 9: Bake
- Place the cake in the preheated oven and bake for about 40–45 minutes, or until a toothpick inserted into the center comes out clean.
Step 10: Cool and Serve
- Allow the cake to cool in the pan for at least 15 minutes before slicing. Enjoy warm or at room temperature for the best flavor and texture!
