Ingredients

Scale
  • 1 box (15.25 oz) yellow cake mix
  • 3 large eggs, room temperature
  • 1/2 cup vegetable oil
  • 1 cup sour cream
  • 1 cup mashed ripe bananas (about 2 large bananas)
  • 1 teaspoon vanilla extract
  • 1/2 cup unsalted butter, softened
  • 1 cup creamy peanut butter
  • 2 cups powdered sugar
  • 1/4 cup whole milk
  • 1 teaspoon vanilla extract
  • Pinch of salt (if using unsalted butter)
  • 1/2 cup chopped roasted peanuts (optional)
  • 1/4 cup chocolate shavings or mini chocolate chips (optional)
  • Sliced fresh banana (for serving, optional)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan thoroughly with butter or non-stick spray; dust with flour if desired.
  2. In a small bowl, mash ripe bananas with a fork until mostly smooth; set aside.
  3. In a large mixing bowl, whisk together eggs, vegetable oil, sour cream, mashed bananas, and vanilla extract until smooth and pale yellow, about 30 seconds.
  4. Add the yellow cake mix to the wet ingredients and stir with a spatula or wooden spoon until just combined. Do not overmix; a few streaks of flour are okay.
  5. Pour the batter into the prepared pan and spread evenly. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. Edges should be golden brown and pulling away from the pan.
  6. Place the pan on a cooling rack and let the cake cool completely (at least 1 hour, preferably 2 hours).
  7. While the cake cools, make the frosting: In a medium bowl, beat softened butter and peanut butter together with a hand mixer until smooth and creamy, about 1 minute. Scrape down sides.
  8. Gradually add powdered sugar, 1/2 cup at a time, mixing on low speed. Add vanilla extract and 2 tablespoons of milk. Beat on medium-high until fluffy, about 2 minutes. If too thick, add another tablespoon of milk; if too thin, add more powdered sugar.
  9. Once the cake is completely cool, spread the peanut butter frosting evenly over the top using an offset spatula or leave it rustic with swirls.
  10. Immediately sprinkle with chopped peanuts and chocolate shavings (if using) while frosting is still soft so they stick.

Notes

For best results, use very ripe bananas with brown spots. Room temperature ingredients ensure a tender crumb. Do not overbake; a toothpick should have a few moist crumbs. Frosting can be adjusted with milk or powdered sugar for desired consistency. Cake tastes even better the next day.
