Banana Sheet Cake with Cream Cheese Frosting

This Banana Sheet Cake is chock full of banana flavor and has a not too sweet Cream Cheese Frosting.


  • 1 2/3 cups sugar
  • 1/3 cup butter, softened and at room temperature
  • 2 eggs (extra-large preferred)
  • 1 teaspoon vanilla
  • 2 1/4 cups flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 1/2 cups mashed banana (about 3 1/2 large)
  • 2/3 cup buttermilk
  • 2/3 cup chopped walnuts, pecans or mini chocolate chips
  • Cream Cheese Frosting


Preheat oven to 350 degrees. Grease and flour jelly roll pan, 10 1/2 by 15 inches. Set aside.

Beat sugar and butter in a large bowl. (Will look “crumbly.”) Add in eggs and vanilla.

In another bowl, mix flour, baking soda and salt with a whisk until well blended. Add to butter mixture, making sure to use a spatula to mix in flour from bottom. It’s ok if it’s not completely smooth.

Beat in mashed bananas and buttermilk at low-speed. Stir in walnuts, pecans or chips by hand.

Bake for 20 to 30 minutes (the larger size pan bakes more quickly) until the corners are just pulling away from the sides of the pan and the top when gently pressed in the center, springs back. Turn halfway through baking.
