Banana Bread

Preheat oven to 350°F. Spray the bottom only of a 9 x 5 x 3-inch loaf pan with nonstick cooking spray.

Beat butter in a large bowl until light and fluffy. Add sugars; beat well. Add egg, egg whites, and vanilla; beat until well blended. Add banana and beat on high speed for 30 seconds.

Combine flour, baking soda, salt, and baking powder in a medium bowl. Add to the butter mixture, alternating with cream, ending with the flour mixture. Add walnuts to the batter; mix well.

Pour batter into the loaf pan. Bake until browned and a toothpick inserted near the center comes out clean, about 1 hour 15 minutes.

Cool in the pan on a wire rack for 10 minutes. Remove from pan; cool completely on the wire rack.
