For the Cake:

• 1/2 cup unsalted butter, softened
• 3/4 cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup sour cream
• 1/4 cup milk
• 1 1/2 cups all-purpose flour

Instructions

Here’s how to make this bakery-worthy treat:

1. Preheat Oven: Set your oven to 350°F (175°C). Grease a 9-inch square baking pan or line it with parchment paper.
2. Make the Streusel: In a small bowl, mix flour, brown sugar, and cinnamon. Cut in the cold butter with a pastry cutter or fork until crumbly. Set aside.
3. Cream Butter and Sugar: In a large mixing bowl, cream butter and granulated sugar together until light and fluffy.
4. Add Eggs and Flavorings: Beat in eggs, one at a time. Stir in vanilla, sour cream, and milk until combined.
5. Combine Dry Ingredients: In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
6. Mix Batter: Gradually add the dry ingredients to the wet mixture and mix until just combined. Do not overmix.
7. Add Blueberries: Gently fold in the blueberries, being careful not to burst them.
8. Pour and Top: Spread batter evenly into the prepared pan. Sprinkle the streusel topping generously over the batter.
9. Bake: Bake for 40–45 minutes or until a toothpick inserted in the center comes out clean.
10. Cool and Serve: Let the cake cool for at least 15 minutes before slicing. Serve warm or at room temperature.
