Ingredients

Banana Sheet Cake

  • 1 box white cake mix {13.25 ounces}
  • 1 teaspoon baking soda
  • ½ teaspoon cinnamon
  • ¼ teaspoon nutmeg
  • ¼ teaspoon salt
  • ¾ cup milk {I used 2%}
  • ½ cup vegetable oil
  • 3 large eggs
  • 3 medium ripe bananas {mashed}

Banana Pudding Frosting

  • 1 cup milk {I used 2%}
  • 1 box banana cream instant pudding mix {3.4 ounces}
  • 1 cup whipped topping

Instructions

  • Preheat the oven to 350 degrees.

Banana Sheet Cake

  • Combine the cake mix, baking soda, cinnamon, nutmeg and salt in a large bowl and whisk to combine.  Add the milk, vegetable oil, eggs and ripe bananas  to the dry ingredients and mix together using a hand held mixer until well blended {1-2 minutes}. 
  • Spray a 9x13 baking dish with nonstick spray. Pour the cake batter into the prepared pan and spread out evenly.  Bake in the preheated oven for 30-35 minutes or until a toothpick inserted in the center comes out with a few crumbs {but no raw cake batter}.  Remove from the oven and allow the cake to cool completely before frosting.

Banana Pudding Frosting

  • To make the frosting combine the milk and instant pudding mix in a medium bowl. Mix together using a handheld mixer until combined.  Add the whipped topping and fold it into the pudding until completely incorporated, being careful to not deflate the whipped topping. 
  • Pour the frosting onto the cooled cake and spread out into an even layer.  Cut into 16 pieces and top with fresh banana slices right before serving {if desired}.
