This classic, simple recipe for banana nut bars is perfect anytime you have extra bananas to use up.
Serves: 12 bars
  • ⅔ cup butter, softened
  • 1 ½ cups sugar
  • 2 eggs, separated
  • 1 cup mashed bananas (from about 3 bananas)
  • 1 ½ cups all purpose flour
  • 1 teaspoon baking soda
  • ¼ teaspoon salt
  • 4 tablespoons sour cream
  • ½ teaspoon vanilla
  • ¼ cup chopped walnuts or pecans
  • Powdered sugar, for sprinkling
  1. Line a 13” by 9” baking pan with aluminum foil and butter the foil. Leave enough overhang on the short sides to lift the foil out after the bars bake. Preheat the oven to 325°F.
  2. Cream the butter and sugar in the bowl of a stand mixer (or a large bowl and a hand mixer). Add the egg yolks and vanilla and beat until combined, then stir in the mashed bananas.
  3. In a separate bowl, stir together the flour, baking soda, and salt.
  4. With the mixer on the lowest setting, add half of the dry ingredients to the bowl, followed by the sour cream and the rest of the dry ingredients. Stir until just combined.
  5. In a separate bowl, whip the egg whites until they form stiff peaks. With a rubber spatula, fold the egg whites into the batter by hand until no white streaks remain. Gently stir in the nuts.
  6. Pour the batter into the prepared pan and smooth the top with a rubber spatula. Bake for 45 minutes, or until a tester inserted into the middle of the pan comes out clean. Allow to cool in the pan, then pull out the foil and slice into bars.
  7. Sprinkle with powdered sugar and serve.
