First, you’ll need to do a little prep work. Grab two mixing bowls, a large one and a smaller one that is microwave safe. Also grab your cooling rack and a plate, bowl or cookie sheet to put under it to catch excess frosting. Parchment paper, tinfoil or even a cutting board would work as well.
Open the can of frosting. Scoop all of the frosting into the small bowl and set it aside for now.
Next, take the wrappers off all of the Twinkies and place them in the large bowl.
