BANANA CUPCAKES WITH PEANUT BUTTER FROSTING


Cupcakes:

1¼ c flour
1½ tsp baking powder
½ tsp baking soda
¼ tsp salt
2 very ripe bananas, peeled
½ c sour cream
1½ tsp vanilla
¾ c white sugar
½ c unsalted butter, at room temperature
1 large egg
1 large egg yolk

Frosting:

1½ c icing sugar
1 - 8 oz package cream cheese, at room temperature
½ c unsalted butter, at room temperature
½ c smooth peanut butter (do not use old-fashioned or freshly ground)
Chopped lightly salted roasted peanuts (optional)

For cupcakes:
Preheat oven to 350°.

Line 12 standard muffin cups with paper liners. Whisk flour, baking powder, baking soda and salt in a medium bowl to blend. In another medium bowl, mash bananas with a fork until smooth. Mix sour cream and vanilla into bananas.

Using electric mixer, beat sugar and butter in a large bowl until light and fluffy, about 3 minutes. Add egg and egg yolk and beat until well blended. Add flour mixture in 3 additions alternately with banana-sour cream mixture in 2 additions, beginning and ending with flour mixture and beating just until blended after each addition. Divide batter among prepared muffin cups.

Bake cupcakes until tester inserted into center of each comes out clean, about 20 minutes. Transfer cupcakes to rack and let cook completely.

For icing:

Sift icing sugar into a large bowl. Add cream cheese, butter and peanut butter. Using electric mixer, beat mixture until smooth. Spread frosting over top of cupcakes, dividing equally. Sprinkle lightly with chopped peanuts, if desired.
