1. Preheat oven to 350 degrees. Grease 9-inch square baking pan with butter or coat with nonstick cooking spray.
  2. Combine butter, lemon rind and 7/8 cup sugar in a mixing bowl. Beat with an electric mixer at medium-high speed until light and fluffy. Add egg and vanilla; beat until combined.
  3. Toss blueberries with 1/4 cup flour. In a separate bowl, whisk together remaining 1-3/4 cup flour, baking powder and salt.
  4. Add flour mixture to egg mixture a little at a time, alternating with buttermilk. Fold in blueberries.
  5. Spread batter in prepared pan. Sprinkle batter with remaining 1 tbsp sugar. Bake 35-45 minutes, until a toothpick inserted in the center comes out clean. Let cool at least 15 minutes before serving.
