Step 1

Preheat oven to 375°F and line a cupcake pan with cupcake liners and set it aside.

Step 2

Combine all of the cupcake ingredients in a stand mixer and beat until combined.

Step 3

Fill the cupcake liners ½ – ¾ full with the batter.

Step 4

Reduce heat to 350°F and bake for 18 to 22 minutes until a toothpick comes clean from the center.

Step 5

Remove from oven and transfer the cupcakes to wire racks to cool completely before frosting.

Step 6

In a stand mixer fitted with a paddle attachment, cream the butter until smooth. Add the sugar 1 cup at a time, mixing at low speed, until incorporated. Increase mixing speed and beat for about 2 minutes, scraping down the sides of the bowl as needed.

Step 7

Reduce speed to low and add in the vanilla, heavy cream, and gel coloring. Increase speed to medium-high to whip for an additional 2 minutes.

Step 8

Use a 1M piping tip to frost the cupcakes.

Step 9

Using the back of a small spoon, evenly spread a tiny bit of peanut butter on the peanut butter cup.

Step 10

Dip the peanut butter topped peanut butter cups into the coin sprinkles/confetti sprinkles. Then add more peanut butter if needed and another layer of sprinkles so it stands up more like a bunch of “coins”.

Step 11

Press the peanut butter cup into the frosting of the cupcake.

Step 12

Take the Airheads Extremes and stick each end into the frosting to make the rainbow.
