Peanut Butter Banana Stuffed Devils Food Cupcakes

Confession: I’m sort of disappointed in myself right now.  These peanut butter banana stuffed devils food cupcakes are the reason why…


They are freakishly good Devils food cupcakes that I stuffed to the gills with peanut butter and bananas, then topped with a chocolate peanut butter icing.

To clarify, I’m not disappointed in myself for MAKING them.  Oh NO sir-ee bob.  They are out-of-this-world yummi!  I’m disappointed because I had a complete lack of self-control and restraint when it came to consumption of them.  I’m not even remotely kidding, you guys.  Even the BATTER was sinfully good.  I lost count after eating the 3rd cupcake.  Maybe I lost count because I passed out from insulin shock or something.  I’m not quite sure…

All I know with 100% assurance is that I was a complete oinker over these cupcakes.  Just set up a trough and start practicing your best pig call.  I’ll be over your way in a flash.  But be sure to make a batch or four of these before you call me.  Otherwise, you may have a wild boar on your hands.  *oink*

For the Cupcakes

  • 3/4 cup (3.3 oz.) cake flour
  • 1/2 cup (2.2 oz.) all-purpose flour
  • 1/2 cup unsweetened Dutch- process cocoa powder
  • 1 teaspoon baking soda
  • 1/4 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup plus 2 tablespoons (5 oz.) unsalted butter at room temperature
  • 1 1/2 cups (11 oz.) granulated sugar
  • 3 large eggs
  • 1/2 cup (4 oz.) buttermilk
  • 1 teaspoon vanilla extract
  • 1/2 cup (4 oz.) strong coffee

For the filling

  • 1 large over ripe banana mashed
  • 1/2 cup creamy peanut butter
  • 1 cup powdered sugar

For the frosting

  • 1/2 cup (4 oz.) unsalted butter at room temperature
  • 1/4 cup chocolate flavored peanut butter
  • 1 cup powdered sugar sifted
  • 1 to 2 teaspoons whole milk if needed, to thin out frosting
  • 3 tablespoons roasted and lightly salted chopped peanuts optional
  • 18 dried banana chips optional


  • Heat oven to 350 degrees F.
  • Place 18 cupcake liners into muffin tins.
  • In a medium sized bowl, sift the cake flour, cocoa powder, baking soda, baking powder and salt together.
  • In the bowl of a stand mixer (or in a large mixing bowl), beat the butter and sugar together at high speed for 15 seconds until combined and creamy.
  • Add the eggs, one at a time, beating until each is incorporated. Continue beating until light and fluffy, about 6 more minutes.
  • With the mixer at its lowest speed, beat in one-third of the flour mixture. Beat in the buttermilk and vanilla, then another one-third of the flour mixture. Beat in the coffee and then the remaining flour mixture.
  • Fill the muffin cups 3/4 full and bake for 18-23 minutes, or until the centers spring back when lightly pressed. Set the pans on a rack to cool.
  • While the cupcakes are cooling, prepare the filling by placing the peanut butter, banana, and confectioner's sugar into a medium bowl. Use a large spoon or hand mixer on high speed to combine until no lumps remain.
  • Use a small spoon or apple corer to make a hole in the center of each cupcake. (Reserve the top so the hole can be covered after you've stuffed the cupcakes.)
  • Spoon stuffing into a piping bag fitted with a #11 tip or gallon sized plastic with the corner snipped off.
  • Fill each cupcake and plug the holes with reserved cupcake pieces.
  • For the frosting
  • With an electric or stand mixer, beat together the butter and peanut butter until smooth. Gradually beat in the powdered sugar until the frosting is light and fluffy. (If needed, add milk 1/2 teaspoon at a time to make the frosting smooth.)
  • Frost the cupcakes. Optional: Sprinkle the tops with an even amount of the chopped peanuts and garnish the tops of each cupcake with a dried banana chip.
  • Makes 18 cupcakes
