Ingredients

  • ½ cup unsalted butter, room temperature
  • ¾ cup granulated sugar, plus 1 Tbsp. for topping
  • 1 tsp. lemon zest
  • 1 large egg, room temperature
  • 1 tsp. vanilla extract
  • 2 cups gluten-free all-purpose flour
  • 1 tsp. xanthan gum
  • 2 tsp. baking powder
  • 1 tsp. salt
  • ½ cup buttermilk
  • 2 cups frozen Maine blueberries, thawed
  • 2 Tbsp. powdered sugar

Directions

  • Preheat oven to 350°F. Grease an 8" × 8" square pan with butter.
  • In a large mixing bowl, cream the butter and sugar until light and fluffy. Add the lemon zest, egg, and vanilla and beat for 1 minute.
  • In a separate bowl, combine the flour, xanthan gum, baking powder, and salt.
  • Add the dry ingredients to the wet ingredients alternately with the buttermilk, beginning and ending with the flour mixture. The batter will be thick.
  • Gently fold in the blueberries. Pour into the prepared pan and bake for 40–50 minutes or until a toothpick inserted in the center comes out clean. Let cool slightly, then dust with powdered sugar.
