1/3 cup store-bought vanilla frosting
1 Tbsp cocoa powder
¼ cup powdered sugar
10 peanut butter-filled pretzels, smashed
1 large, store-bought chocolate muffin
Pack frosting in a small screw-top container. Blend cocoa powder and powdered sugar in a zip-top bag. Pack smashed pretzels and muffin in separate bags.
Crumble muffin into a large pot or bowl, breaking up lumps to create the smallest possible pieces. Stir in frosting, blending well so that a stiff, sticky dough forms. Add smashed pretzels, continuing to stir until well blended. Using your hands, form inch-wide balls and set on a plate. One at a time, drop balls into powdered sugar mixture, tossing gently to coat.
