Banana Cake with Fluffy Peanut Butter Frosting

Banana Cake with PB Frosting

When my mom begins an email with, “gotta share these two new and fabulous recipes with you!”, I know I’m in for a treat.

The summer humidity where my mom lives makes bananas ripen quicker than they get eaten. After making multiple loaves of banana bread, she went searching for a different recipe to utilize her browning nanners and a spare cake mix. What she found was a simple and versatile (you could use any flavor cake mix) recipe that yields a moist, tender cake with a mild, but distinct, banana flavor.

My mom and I share an affinity for banana bread and peanut butter sandwiches. With that in mind she found a fluffy peanut butter frosting to adorn the banana cake and mimic the taste of those tasty sandwiches we so love.

The result of these two new recipes is indeed fabulous!

  • yellow cake mix
  • eggs, oil, and water (ingredients listed on the box to make cake)
  • 2 overripe bananas
  • 1 tsp baking soda

Create cake batter according the package instructions. In a separate bowl, mash the two bananas. Mix the baking soda into the bananas until thoroughly mixed – it will look lighter and slightly foamy. Add banana mixture to the cake batter and stir until combined.

Pour banana batter into a greased 9 x 13 pan. Bake according to package directions. Let cool completely and frost with Fluffy Peanut Butter Frosting (below).

  • 1/2 cup butter, softened
  • 1 cup creamy peanut butter
  • 1 1/2 cups powdered sugar
