Equipment

  • Cake Pan
  • Spatula
  • Knife
  • Freezer-safe Container

Ingredients
  

Main Ingredients

  • 1 box chocolate cake mix prepared according to package instructions
  • 2 cups vanilla ice cream slightly softened
  • 1 cup smooth peanut butter
  • 1 cup chopped Reese’s cups
  • whipped cream for topping
  • chocolate syrup for drizzling

Instructions
 

  • Preheat your oven and prepare the chocolate cake mix according to the package instructions. Bake until a toothpick inserted comes out clean.
  • Let the cake cool completely on a wire rack. This ensures clean slices and prevents melting during layering.
  • Once cooled, carefully slice the cake horizontally into two even layers using a serrated knife.
  • Spread a layer of smooth peanut butter over the bottom cake layer, then top it with a layer of vanilla ice cream. Sprinkle chopped Reese’s cups on top.
  • Place the second cake layer on top and repeat the process with peanut butter, ice cream, and Reese’s cups.
  • Top the cake with whipped cream and drizzle with chocolate syrup for a decadent finish.
  • Freeze the assembled cake for at least 4 hours (or overnight) until fully set before serving.

Notes

For extra flair, top with crushed nuts, caramel drizzle, or fresh fruit before freezing. Slice with a warm knife for cleaner cuts. Store in the freezer in an airtight container for up to two weeks.
