Ingredients

  • 2 cups fresh blueberries
  • 2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1 teaspoon kosher salt
  • ½ cup unsalted butter room temperature
  • 2 teaspoons lemon zest
  • ¾ cup + 2 tablespoons sugar
  • 1 egg
  • 1 teaspoons vanilla extract
  • ½ cup buttermilk

Instructions

  • Preheat the oven to 350 degrees. Grease a 9-inch square baking dish with butter.
  • In a small bowl, toss the blueberries with ¼ cup of flour; set aside. Whisk together the remaining flour, baking powder and salt in a medium bowl and set aside.
  • In the bowl of an electric mixer fitted with the paddle attachment, cream the butter, lemon zest and ¾ cup plus one tablespoon of the sugar together until light and fluffy. Add the egg and vanilla and beat until combined.
  • Add the flour mixture to the batter a little at a time, alternating with the buttermilk. Fold in the blueberries.
  • Spread batter into greased baking dish and sprinkle batter with remaining tablespoon of sugar. Bake for 35-45 minutes, or until top is slightly golden brown and a toothpick inserted into the center comes out clean. Allow to cool for 10-15 minutes before serving.

Notes

  • Toss the blueberries in flour to help prevent sinking.
  • Fresh blueberries provide the best texture, but frozen blueberries also work.
  • Avoid overmixing the batter to keep the cake soft and tender.
  • Tent loosely with foil if the top browns too quickly.
  • Store covered at room temperature for best texture.
