SUBSTITUTIONS FOR CHOCOLATE PEANUT BUTTER CUPCAKES

PEANUT BUTTER CUPS: You can substitute chopped full-size or miniature peanut butter cups for the whole mini unwrapped peanut butter cups for this sweet treat.

CAKE MIX: You can substitute chocolate fudge cake mix for the chewy fudge brownie mix for the rich chocolate cupcakes if you only have cake mix on hand. You will need to follow the box directions on the ingredients.

FROSTING: You can substitute canned chocolate whipped frosting for the homemade peanut butter frosting in this delicious recipe.

HOW TO MAKE REESE’S CUPCAKES

STEP ONE: Preheat the oven to 350°F. Line 2 standard-size muffin pans with cupcake liners. Light spray the liners with nonstick spray. Set them aside.

STEP TWO: Add the brownie mix to a medium-sized mixing bowl.

STEP THREE: Add in the oil, water, and the beaten eggs. Stir just until combined. Do not overmix.

OUR RECIPE DEVELOPER SAYS

Do not overmix the batter once you have added all of the ingredients together. This can make tough cupcakes.

STEP FOUR: Place one of the Reese‘s peanut butter cups in the bottom of each cupcake liner.

STEP FIVE: Spoon 1½ tablespoons of the brownie mix on top of each peanut butter cup.

STEP SIX: Bake for 20 minutes until a toothpick inserted in the center of the cupcake comes out clean. Allow the cupcakes to cool completely before frosting.

PRO TIP:

Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to keep a close eye on your cupcakes as the suggested baking time approaches.

HOW TO MAKE PEANUT BUTTER FROSTING

STEP SEVEN: Using either a stand mixer or a medium-sized mixing bowl and a handheld mixer on medium-high speed, beat together the butter, peanut butter, and vanilla extract for 1½ to 2 minutes, until smooth.

STEP NINE: Once the cupcakes are completely cooled, fill a decorator’s or piping bag fitted with an open star tip or a gallon-size Ziploc with a corner snipped off with the frosting.

STEP TEN: To frost the cupcakes, hold the decorator’s bag about ½ inch from the center surface of the cupcake. Use even pressure, and squeeze to form the center of the star-swirl. Keeping the tip elevated and using the same pressure, follow the outer line of the star-swirl, making a C shape around the star-swirl until the outer swirl lines connect. Repeat for the remaining cupcakes.

STEP ELEVEN: Sprinkle a few of Reese’s mini unwrapped candies over the frosted cupcakes.

PRO TIP:

The mini cups can be cut in half when decorating the top of the peanut butter Reese’s cupcakes.
