•

1 ½ teaspoons baking powder
•

½ teaspoon baking soda
•

¼ teaspoon salt
•

2 very ripe bananas
•

½ cup sour cream
•

1 ½ teaspoons vanilla extract
•

¾ cup white sugar

•

½ cup unsalted butter, at room temperature

1 large egg

Instructions

Preheat the oven to 350 degrees F (175 degrees C). Line a 12-cup muffin pan with paper liners.
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.
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.
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.
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.
