Ingredients
Scale
- 2 cups all-purpose flour, divided
- 3/4 cup granulated sugar
- 1/2 cup light brown sugar, packed
- 2 teaspoons baking powder
- 1/4 teaspoon baking soda
- 1/2 teaspoon salt
- 10 tablespoons unsalted butter, melted and divided
- 3/4 cup sour cream
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 1/2 cups fresh blueberries
- 1 teaspoon ground cinnamon
Instructions
- Preheat the oven to 350°F (175°C). Grease an 8×8-inch baking pan and line with parchment paper if desired.
- Make the crumb topping by stirring together 3/4 cup flour, light brown sugar, ground cinnamon, and 4 tablespoons melted butter until crumbly.
- In a large bowl, whisk together the remaining 1 1/4 cups flour, granulated sugar, baking powder, baking soda, and salt.
- In a separate bowl, whisk together the sour cream, eggs, vanilla extract, and remaining 6 tablespoons melted butter until smooth.
- Add the wet mixture to the dry ingredients and stir just until combined.
- Toss the blueberries with 1 teaspoon flour, then gently fold them into the batter.
- Spread the batter evenly into the prepared pan and smooth the top.
- Sprinkle the crumb topping evenly over the batter.
- Bake for 38 to 45 minutes, until the top is golden and a toothpick inserted in the center comes out with a few moist crumbs.
- Cool in the pan for at least 20 minutes before slicing into 9 squares and serving.
Notes
- Tossing the blueberries in flour helps keep them from sinking.
- Do not overmix the batter or the cake may turn dense.
- Frozen blueberries can be used straight from the freezer.
- Store covered at room temperature for up to 2 days or refrigerate for up to 5 days.
