Ingredients Method Notes

Ingredients
  

  • 2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter softened
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup sour cream or Greek yogurt
  • 1 1/2 cups fresh or frozen blueberries
  • 1 tablespoon flour for coating blueberries
  • 1/2 cup brown sugar
  • 1/2 cup all-purpose flour for crumb topping
  • 1 teaspoon ground cinnamon
  • 1/4 cup unsalted butter melted

Method
 

  1. Preheat oven to 350°F and grease or line a 9-inch baking pan.
  2. In a bowl, mix flour, baking powder, baking soda, and salt.
  3. In a separate bowl, cream butter and sugar until light and fluffy.
  4. Add eggs one at a time, then mix in vanilla.
  5. Alternate adding dry ingredients and sour cream, mixing just until combined.
  6. Toss blueberries with 1 tablespoon flour and gently fold into batter.
  7. Spread batter evenly into prepared pan.
  8. Mix brown sugar, flour, cinnamon, and melted butter to form crumbs.
  9. Sprinkle crumb topping evenly over batter.
  10. Bake for 40–45 minutes until a toothpick inserted comes out clean.
  11. Cool for at least 20 minutes before slicing and serving.

Notes

Tossing blueberries in flour helps prevent sinking. For extra crunch, chill the crumb topping briefly before baking.
