Description

Peanut butter and bananas are a perfect match in this banana cupcake recipe with a decadent peanut butter and cream cheese frosting.

Ingredients

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 bananas
1/2 cup sour cream
1 1/2 teaspoons vanilla extract
3/4 cup white sugar
1/2 cup unsalted butter, at room temperature
1 large egg
1 large egg yolk
1 1/2 cups powdered sugar
1 (8 ounce) package cream cheese, at room temperature
1/2 cup unsalted butter, at room temperature
1/2 cup smooth peanut butter

Directions

1 Preheat the oven to 350 degrees F (175 degrees C). Line a 12-cup muffin pan with paper liners.
2 Whisk flour, baking powder, baking soda, and salt together in a medium bowl. Mash bananas with a fork in another medium bowl until smooth. Mix sour cream and vanilla extract into bananas.
3 Combine sugar and butter in a large bowl; beat with an electric mixer until light and fluffy, about 3 minutes. Add egg and egg yolk and beat until well blended. Add flour mixture in 2 batches, alternating with banana mixture, beating batter briefly after each addition until just blended. Scoop batter into the prepared muffin cups, adding about a generous 1/4 cup in each.
4 Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 20 minutes. Cool in the tin for 5 minutes. Transfer to a wire rack to cool completely, about 20 minutes.
5 Meanwhile, sift powdered sugar into a large bowl. Add cream cheese, butter, and peanut butter; beat with an electric mixer until smooth. Spread or pipe frosting onto the cooled cupcakes.
