Ingredients
Scale
- 2 cups all-purpose flour + 1 tablespoon, divided
- 2 cups blueberries, divided
- 3 teaspoons baking powder
- ½ teaspoon salt
- ½ cup unsalted butter, softened
- ½ cup granulated sugar
- 1 large or x-large egg
- 1 teaspoon pure vanilla extract
- ½ cup sour cream
- ½ cup milk
- 2 tablespoons lemon zest
- ½ cup all-purpose flour
- ⅓ cup light brown sugar packed
- 1 teaspoon ground cinnamon
- ¼ teaspoon salt
- ¼ cup unsalted butter melted
- ½ cup powdered sugar
- 2 tablespoons lemon juice
Instructions
- Preheat the oven to 350 degrees F and lightly grease a 9-inch round springform pan.
- In a small bowl, mix together the ½ cup flour, brown sugar, cinnamon, salt, and melted butter until crumbly; set aside.
- Coat 1½ cups of blueberries with 1 tablespoon of flour in another bowl; set aside.
- In a large mixing bowl, whisk together 2 cups of flour, baking powder, and salt.
- In another bowl, cream the softened butter, granulated sugar, and egg for 2-3 minutes until light and fluffy. Add sour cream, lemon zest, milk, and vanilla, mixing until combined. Gradually incorporate the flour mixture until smooth.
- Gently fold the blueberries into the batter without overmixing. Spread batter into the prepared pan, add remaining blueberries on top, and sprinkle with streusel mixture.
- Bake for 45-55 minutes, or until a toothpick comes out clean from the center. Cool on a wire rack for 20 minutes before removing the ring from the springform pan. Allow to cool for at least 1 hour before glazing.
- Mix powdered sugar and lemon juice, drizzle over the cooled cake if desired.
Notes
Ensure not to overmix the batter to keep the blueberries intact.
Can be stored in an airtight container for up to 3 days, or frozen for longer freshness.
