  • Sift flour, baking powder, baking soda, and salt together in a bowl.

  • Beat brown sugar, peanut butter, and 2 tablespoons butter together in a bowl using an electric mixer on medium speed until creamy, about 1 minute. Beat banana, eggs, and 1 1/2 teaspoons vanilla extract into creamed peanut butter mixture until incorporated, about 1 minute.

  • Beat flour mixture, alternating with 1/2 cup milk, into creamed peanut butter mixture until batter is well combined; pour into muffin cups.

  • Bake in the preheated oven until a toothpick inserted in the center of a cake comes out with moist crumbs, 20 to 23 minutes. Cool cupcakes in the tin for 15 minutes before transferring to a wire rack to cool completely.

  • Beat marshmallow fluff, 2 tablespoons butter, shortening, and 1 teaspoon vanilla extract together in a bowl using an electric mixer until smooth. Gradually beat confectioners' sugar, alternating with 2 tablespoons milk, into marshmallow mixture until desired thickness is reached; chill in refrigerator until thickened, about 15 minutes.

  • Spread frosting over cupcakes or pipe through a pastry bag.

OMG!!! Best cake EVER! This tastes like a peanut butter and banana sandwich only sweeter! They had the PERFECT texture! Light and fluffy and moist! They took me an hour and a half but totally worth it!!!!! I used the cake recipe for cake pops and with a thin vanilla glaze on them it just topped it off perfectly! I will absolutely make these again! (; Read More

these were fun to make however I didn't have the marshmallow fluff so I improvised and roasted marshmallow using the low broilers for the last 30 seconds of their baking and when they came out of the oven I smooshed the marshmallows so it covered the top of the cupcake.They are a tad on the sticky side but my kids don't seem to care Read More

It was easy to make and went over well. The peanut butter was a little heavy so it should be cut back a little to keep from hiding the bananas quite so much. I only fill d the cups about 1/2 way and they baked to about 3/4's full. Topped with a chocolate ganache then the marshmallow topping. Definitely one to keep and make again. Read More

The peanut butter overwhelmed the cupcake so you didn't get any real taste of banana. I doubled the recipe thinking I would get 2 dozen... I got 3 dozen. Next time I would lessen the peanut butter and add a little more banana. FYI I topped with chocolate icing. The kids loved it though. Read More
