  • 1/4 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/4 cup brown sugar

Instructions

  1. Preheat the oven to 350°F (175°C). Grease and flour a 9-inch square baking pan.
  2. In a medium bowl, whisk together 1 1/2 cups flour, baking powder, baking soda, salt, and 1/2 cup sugar.

  4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
  5. Gently fold in the fresh blueberries.
  6. Pour the batter into the prepared pan and spread evenly.
  7. For the crumb topping, combine the remaining 1/2 cup flour, brown sugar, cinnamon, and 1/4 cup softened butter. Mix until crumbly.
  8. Sprinkle the crumb topping evenly over the batter.
  9. Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
  10. Allow the cake to cool in the pan before slicing and serving.

Notes

For extra flavor, serve with a dollop of whipped cream or a drizzle of lemon glaze.
