Prep Time: 20 mins

Cook Time: 50 mins

Total Time: 1 hr 10 mins


For the cake:

  • 3/4 cup sugar
  • 2 tablespoons lemon zest from one medium lemon
  • 1/2 cup butter softened
  • 1 egg
  • 1 teaspoon vanilla
  • 2 cups + 1 tablespoon flour divided
  • 2 teaspoons baking powder
  • 1 teaspoon salt
  • 2 cups fresh blueberries
  • 1/2 cup buttermilk

For the streusel:

  • 2 tablespoons cold butter cut into pieces
  • pinch of salt
  • 2 tablespoons flour
  • 2 tablespoons sugar


  1. Preheat the oven to 325F. Grease an 8″ x 8″ square baking dish or a 9 inch cake pan, and set aside.
  2. In a large bowl, combine the sugar and lemon zest. Rub the zest into the sugar with your fingers, until fragrant. Add the butter and beat until light and fluffy. Add the egg and vanilla and mix until combined.
  3. In a small bowl, whisk together 2 cups flour, the baking powder, and the salt. Add 1/3 of the flour mixture to the butter mixture, mix until nearly combined, then add half of the buttermilk. Repeat with the remaining flour mixture and buttermilk, ending with the flour.
  4. In a small bowl, toss together the blueberries and flour. Add the blueberries to the cake batter, and gently fold in, being careful not to crush the blueberries. Pour the batter into the prepared pan.
  5. To make the streusel, combine the butter, flour, sugar, and salt in a small bowl. Using a pastry blender or two knives, cut in the butter until the pieces are no larger than pea sized. Sprinkle the streusel mixture over the top of the cake batter.
  6. Bake 45-50 minutes, or until a toothpick inserted two inches from the side of the pan comes out clean. Let cool slightly before serving.
