Banana & Peanut Butter Cake


  • 3/4 cup all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/4 cup margarine, light, softened
  • 1/3 cup sugar
  • 1 egg
  • 1/4 cup reduced-fat peanut butter
  • 2 tablespoons reduced-fat sour cream
  • 1 large ripe banana, mashed


Preheat the oven to 350 degrees.

  1. Coat an 8-inch round cake pan with cooking spray.
  2. In a small bowl, combine the flour, baking powder, baking soda, and salt; mix well and set aside.
  3. In a large bowl, cream the butter and sugar. Add the egg, peanut butter, sour cream, and banana; mix well.
  4. Add the flour mixture; mix well, then spread into the cake pan.
  5. Bake for 30 to 35 minutes, or until a wooden toothpick inserted in the center comes out clean. Let cool in the pan for 10 minutes, then remove from the pan to cool completely before cutting into wedges.


Even though peanut butter is a good source of protein, it’s high in fat, and should be eaten in moderation… so save this one for special occasions.
