Ingredients

Scale
  • 1 box chocolate cake mix (15.25 oz)
  • 3 large eggs (or as specified on cake mix box)
  • 1/2 cup vegetable oil (or as specified on cake mix box)
  • 1 cup water (or as specified on cake mix box)
  • 1 can sweetened condensed milk (14 oz)
  • 1/2 cup creamy peanut butter
  • Optional: 1/4 cup whole milk or heavy cream
  • 1 tub whipped topping (8 oz, thawed)
  • 1/2 cup hot fudge sauce (warmed)
  • 810 Reese’s Peanut Butter Cups (chopped)
  • Optional: Mini chocolate chips or peanut butter chips for garnish

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or nonstick spray.
  2. In a large bowl, combine chocolate cake mix, eggs, oil, and water as directed on the box. Whisk or beat for about 2 minutes until smooth.
  3. Pour batter into prepared pan and smooth the top. Bake for 28–32 minutes, or until a toothpick inserted in the center comes out clean.
  4. Let cake cool for about 10 minutes. Using the handle of a wooden spoon or thick fork, poke holes all over the cake, about 1 inch apart and 3/4 of the way down.
  5. In a microwave-safe bowl, combine sweetened condensed milk and creamy peanut butter. Microwave in 20-second bursts, stirring until smooth and pourable. Add a splash of milk or cream if needed.
  6. Pour peanut butter mixture evenly over the cake, letting it soak into the holes. Use a spatula to spread if needed.
  7. Let cake cool to room temperature, then refrigerate for at least 1 hour (overnight is even better).
  8. Spread whipped topping evenly over the chilled cake.
  9. Drizzle with warmed hot fudge sauce and scatter chopped Reese’s Peanut Butter Cups on top. Add mini chips or extra peanut butter drizzle if desired.
  10. Refrigerate for another hour for cleaner cuts. Slice into squares and serve chilled or at room temperature.

Notes

For best results, chill the cake before serving for clean slices and melded flavors. Don’t overbake the cake—moist crumbs are ideal. If the peanut butter filling is too thick, add a splash of milk or cream. For gluten-free or dairy-free adaptations, use appropriate cake mix and toppings. Cake can be made a day ahead and freezes well in individual slices.
