The 2-Ingredient Retro Dessert I'm Making for the Holidays

Prepare the pan: Line an 8 x 8-inch square baking dish with parchment paper.

Combine frosting and peanut butter: Combine the frosting and peanut butter in a medium microwave‑safe bowl. Don't worry about mixing them together yet. Microwave on high for 30 seconds, stir with a spatula, and microwave again for 30 seconds. Mix again until completely smooth.

Pour into the pan and refrigerate: Pour into the prepared pan. You can press some chopped peanuts or peanut butter cups into the top or drizzle with melted chocolate if you like. Refrigerate for at least 1 hour to set. Use the parchment to remove from the pan and cut into 24 pieces to serve. Store in an air‑tight container in the fridge for up to a week.
