Blueberry Crumb Cake with Sour Cream

Crumb cake or coffee cake. With fruit or cream, or fruit and cream! Beautiful, plump, juicy blueberries. Sour cream and butter. This beautiful sour cream blueberry crumb cake is perfect anytime you want to treat yourself and your loved ones. The cake is tender, moist and full of flavor, while the crunchy crumb topping adds a buttery caramel flavor.

Look at these beautiful blueberries dusted and ready to explode with sweet, juicy flavor. Oh, and the cake just happens to be super moist with a hint of cinnamon? And easy to make?

This cake looks and smells so yummy as it cools. It tastes even better. I barely get a piece cut before my tasters are at it.

Recipe type: Cake
Serves: 10
  • Crumb Topping
  • 1 cup all-purpose Flour
  • ¼ cup granulated Sugar
  • ⅓ cup firmly packed Dark Brown Sugar
  • 1 teaspoon ground Cinnamon
  • ⅛ teaspoon Salt
  • 7 tablespoons unsalted Butter, melted
  • Sour Cream Blueberry Cake
  • 1½ cups all-purpose Flour
  • 1¼ teaspoons Baking Powder
  • ¼ teaspoon Baking Soda
  • ½ teaspoon Salt
  • 1 cup fresh or unthawed frozen Blueberries
  • 1 cup Sour Cream
  • 1½ teaspoons Vanilla Extract
  • 10 tablespoons (1¼ sticks) unsalted Butter, softened
  • 1 cup granulated Sugar
  • 2 large Eggs
  1. Make the topping
  2. In a medium bowl, stir the flour, sugar, brown sugar, cinnamon, and salt until well blended. Add the melted butter and mix with a fork, stirring until the butter is absorbed and the dry ingredients are uniformly moistened. Set aside.
  3. Make The Cake
  4. Position a rack in the center of the oven and preheat the oven to 350 degrees F. Butter and flour the bottom and sides of a 9 or 10-inch springform pan OR a 9 inch square baking pan.
  5. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well blended.
  6. In a small bowl, toss the blueberries with 1 tablespoon of the flour mixture until the berries are coated; set aside. In a small bowl, whisk together the sour cream and vanilla extract; set aside.
  7. In a large bowl, beat together the butter and granulated sugar a medium speed until light and fluffy, about 3 or 4 minutes. Beat in the eggs one at a time, beating well after each addition and scraping down the sides of the bowl as necessary. At low-speed, beat in the flour mixture in three additions, alternating it with the sour cream in two additions. Using a rubber spatula, fold in the blueberries. Scrape the batter into the prepared pan and smooth the top with a spatula.
  8. Sprinkle the crumb topping evenly over the batter, breaking up any large lumps with your fingers.
  9. Bake the cake until a toothpick inserted into the center comes out clean, about 45 minutes. Place the cake in the pan on a wire rack to cool:
  10. If baked in springform pan, cool on rack 20 minutes. Then unlatch springform and cool completely before serving.
  11. If baked in square baking pan, cool completely and cut cake into squares, serving from the pan.
