Ingredients

For the cake:

  • 1 1/3  cups mashed bananas (about 2 large or 3 small bananas)
  • 1 1/2  cups  buttermilk
  • cups  all-purporse flour , sifted
  • 1/2  tablespoon  baking soda
  • 1/4  teaspoon  salt
  • 1/3  cup  unsalted butter , softened
  • 1/3 cup vegetable oil
  • 4 tablespoons sour cream
  • cup  granulated sugar
  • 1/2  cup  brown sugar
  • large eggs
  • teaspoons  vanilla extract

For the frosting:

  • oz  cream cheese
  • 1/3  cup  unsalted butter  , softened
  • 3-3 1/2  cups  powdered sugar
  • 1 dash vanilla extract

Instructions

To make the banana cake:

  • Preheat the oven to 350°F. Grease and flour a 9x13-inch cake pan. *see notes for tips
  • Beat together the butter, brown sugar, and white sugar until combined.
  • Add the oil and sour cream and mix again.
  • Add in eggs one at a time, then the vanilla. Mix on high until light and fluffy and smooth.
  • Combine flour, baking soda and salt in a medium bowl, sifting everything together.
  • Add the flour mixture and milk to the egg mixture, stirring just until combined. (Do not over-mix!!).
  • Fold in bananas gently with a rubber spatula.
  • Pour into prepared pan.
  • Put into the oven and immediately reduce the heat to 300ºF. Bake 60 – 70 minutes (see notes below), or just until toothpick inserted in center comes out clean.
  • Open the oven slowly and gently so as to not shake the cake.
  • Remove from oven and place flat in the freezer for 45 minutes to make the cake extra moist.
  • Remove from the freezer into the fridge and once cool completely, frost.

To make the frosting:

  • Cream together butter and cream cheese until fluffy, scraping down the sides as needed.
  • Add vanilla and powdered sugar and beat until smooth.
  • Gently frost the cake and store in the fridge or with a lid on the counter until ready to eat.

Notes

  • To grease and flour a pan: Spray with nonstick spray, then dump in about 1/4 cup of flour. Tilt the pan one direction, tapping the sides as you do it, then turn and repeat until the entire bottom and sides are coated. Turn the pan upside down and tap gently on the bottom to remove excess flour. 
  • This cake is extremely sensitive to ovens so make sure you're baking it through all the way before removing it from the oven. It should be springy to the touch and the toothpick should come out clean. Our cake usually take 54-55 minutes, but occasionally we have a batch that takes longer. Try to resist opening the oven door as much as possible.
