Ingredients
  

For the cake:

  • 2 cups granulated sugar
  • ½ cup unsalted butter (1 stick), softened
  • 2 eggs
  • 3 small very ripe bananas
  • 1 cup buttermilk (see notes below for a DIY version)
  • 2 teaspoons baking soda
  • ½ teaspoon salt
  • 2 cups all-purpose flour
  • 1 teaspoon vanilla extract
  • ½ cup finely chopped walnuts

For the cream cheese frosting:

  • 8 oz cream cheese (1 block), softened
  • ½ cup butter (1 stick), softened
  • 1 teaspoon vanilla extract
  • 2½ cups powdered sugar

Instructions
 

For the cake:

  • Preheat oven to 350°F. Grease a 13x9 inch pan with cooking spray.
  • In a large bowl, whisk together the flour, baking soda, and salt.
  • In another large bowl, beat the sugar and ½ cup butter on high until fluffy, about 2–3 minutes.
  • Add the eggs, vanilla, and bananas, and beat until blended. Scrape down the sides of the bowl with a spatula, if needed.
  • Add half of the flour mixture and half of the buttermilk. Stir gently with a spatula until incorporated.
  • Repeat with the remaining flour mixture and buttermilk. Stir in the walnuts.
  • Pour the batter into the greased 13x9 inch pan. Bake for 20 minutes, then put a piece of aluminum foil over the top to prevent the cake from browning too much. Bake for an additional 15 minutes, or until a toothpick inserted into the center comes out clean.
  • Let the cake cool completely before spreading on the frosting.

For the cream cheese frosting:

  • Beat the butter and cream cheese in a large bowl until creamy, about 2 minutes.
  • Add the vanilla and powdered sugar, one cup at a time, beating after each addition.
  • Spread the frosting on the cooled banana cake. Cut into 15 pieces and serve.
  • Store any leftover cake in the refrigerator.

Notes

To make your own buttermilk, pour 1 tablespoon of vinegar into a measuring cup. Fill the rest of the cup up to the 1-cup line with milk. You can use white vinegar, apple cider vinegar, or white wine vinegar. You can use skim, 1%, 2%, or whole milk. 
This is a very moist, somewhat dense cake. Think banana bread but in cake form! Due to the cream cheese icing, I recommend storing it in the refrigerator. Let the cake sit on the countertop for 30–60 minutes before serving.
