Recipe type: Cake, Dessert
Cuisine: American
Serves: 20
  • For the Cake:
  • 2 sticks (one cup) butter
  • ½ cup water
  • 2 cups unbleached all purpose flour
  • 2 cups granulated sugar (or you could substitute 1 cup with light brown sugar)
  • 2 eggs, room temperature and lightly beaten
  • 1¼ cups ripened bananas, mashed
  • ¼ cup buttermilk or yogurt
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda
  • ¼ teaspoon salt
  • 1 cup walnuts or pecans, chopped and toasted (optional)
  • For the Frosting
  • ¾ cup butter, softened
  • 1 8oz package of cream cheese, softened
  • 1 16oz box of powdered sugar, or weigh the powdered sugar, if you have it in bulk, or measure 4 cups
  • 1 teaspoon vanilla extract
  1. Preheat oven to 400 degrees F.
  2. Lightly grease sheet pan or spray with cooking spray.
  3. In a large bowl fitted with a paddle attachment, add the flour and sugar. Set aside.
  4. In a small saucepan, boil the butter and water. While still hot, pour over the flour/sugar mixture, and stir.
  5. Add the eggs, buttermilk, baking soda and salt.
  6. Mix on low, until all ingredients are combined.
  7. Pour into prepared sheet pan, and bake for 20 minutes.
  8. Remove sheet pan to a cooling rack. Allow to completely cool before applying the frosting.
  9. For the Frosting
  10. In a large bowl fitted with a paddle attachment, cream together the butter and cream cheese, and vanilla. Add the powdered sugar a little at a time, so the sugar doesn't fly everywhere.
  11. Once the frosting ingredients are combined, beat the frosting on medium speed for 7-8.minutes. This increases the volume a bit and makes it somewhat fluffy.
  12. Spread the frosting over the cooled cake. Serve immediately or cover and refrigerate.
In cream cheese frosting, I sometimes add a little zest from a lemon or orange. I like the way the citrus cuts through the richness of the frosting.

This cake will last in the refrigerator for several days. Just be sure to keep it covered.
