  • 2 teaspoons ground cinnamon

Blueberry Crumble Cake Ingredients

  • 3 cups all-purpose flour
  • 4 teaspoons baking powder
  • ½ teaspoon kosher salt
  • 1 cup unsalted sweet cream butter, softened
  • 1 ½ cups granulated sugar
  • 4 large eggs
  • 4 teaspoons pure vanilla extract
  • ½ cup sour cream
  • 1 cup buttermilk
  • 4 cups fresh blueberries

Instructions

  1. Prepare the Crumble Topping: In a large bowl, combine 1 cup flour, ⅓ cup light brown sugar, ⅓ cup sugar, and 2 teaspoons ground cinnamon. Using a fork or your fingers, cut in cold cubed butter until the mixture becomes crumbly. Set aside.
  2. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C). Spray a 9×13 inch baking pan with baking spray to prevent sticking.
  3. Mix Dry Ingredients: In a medium bowl, whisk together 3 cups flour, 4 teaspoons baking powder, and ½ teaspoon kosher salt until well combined.
  4. Cream Butter and Sugar: In a large bowl, beat 1 cup softened butter and 1 ½ cups sugar together until creamy and smooth.
  5. Add Eggs, Vanilla, and Sour Cream: Beat in the 4 eggs one at a time, then add 4 teaspoons vanilla extract and ½ cup sour cream, mixing until well combined.
  6. Incorporate Dry Ingredients and Buttermilk: Gradually beat in the dry flour mixture alternately with 1 cup buttermilk until fully combined, starting and ending with dry ingredients.
  7. Fold in Blueberries: Gently fold 2 ½ cups of fresh blueberries into the batter to evenly distribute without crushing them.
  8. Assemble the Cake: Scoop batter into the prepared pan, smoothing the top evenly. Spread the crumble topping evenly over the batter.
  9. Add Remaining Blueberries: Sprinkle the remaining 1 ½ cups of fresh blueberries over the crumble topping for extra fruitiness.
  10. Bake: Place the cake in the preheated oven and bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
  11. Cool: Remove the cake from the oven and place on a counter to cool completely before serving.

Notes

  • Use fresh blueberries for the best flavor and texture.
  • Make sure the butter for the crumble topping is very cold to create a good crumb texture.
  • Do not overmix the batter after combining wet and dry ingredients to keep the cake tender.
  • You can substitute buttermilk with regular milk plus 1 tablespoon lemon juice if needed.
  • Allow cake to cool completely to make slicing easier and to let flavors develop.
