Banana Cupcakes with Peanut Butter Frosting

| |

When I was  a kid, the only way I would eat a banana was if it had peanut butter on it.  I assumed that was how EVERYONE ate a banana but apparently not.  I have grown accustomed to eating them plain now but, I dunno, bananas just taste better with peanut butter.  It only makes sense, then, that a banana cupcake would be topped with peanut butter frosting. Everything is right with the world now thanks to Lovin From the Oven.

Banana Cupcakes with Peanut Butter Frosting


  • 1 1/4 cups all purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 2 very ripe large bananas, peeled
  • 1/2 cup sour cream
  • 1 1/2 teaspoons vanilla extract
  • 3/4 cup sugar
  • 1/2 cup (1 stick) unsalted butter, room temperature
  • 1 large egg
  • 1 large egg yolk
  • 1 1/2 cups powdered sugar
  • 1 8-ounce package cream cheese, room temperature
  • 1/2 cup (1 stick) unsalted butter, room temperature
  • 1/2 cup smooth peanut butter (do not use old-fashioned or freshly ground)
  • Chopped lightly salted roasted peanuts (optional)


  1. Preheat to 350°F and line 12 standard muffin cups with paper liners.
  2. Mash bananas with fork until smooth. Mix in the sour cream and vanilla.
