Ingredients

Scale

Base and Layers

  • 18 oz graham crackers
  • 1 1/2 cups hot fudge sauce

Cheesecake Filling

  • 1 1/2 cups heavy whipping cream
  • 20 oz Challenge cream cheese, softened
  • 1/2 cup peanut butter
  • 1/2 cup powdered sugar
  • 1 tsp vanilla extract
  • 16 Reese’s (full size, coarsely chopped)

Whipped Cream Topping

  • 1 cup heavy whipping cream
  • 2 tbsp powdered sugar
  • 1/2 tsp vanilla extract

Graham Cracker Crumble

  • 1 cup graham cracker crumbs (from leftover graham crackers)
  • 2 tbsp Challenge unsalted butter, melted
  • 2 tbsp sugar

Instructions

  1. Prepare Graham Cracker Base: Lay graham crackers in a single layer across the bottom of a 9 x 13 inch baking dish, breaking apart pieces as necessary to fit the surface evenly.
  2. Layer Hot Fudge Sauce: Spread half of the hot fudge sauce evenly over the graham crackers and set aside to prepare the filling.
  3. Whip Heavy Cream: Using a stand or hand mixer, whip 1 1/2 cups heavy whipping cream until stiff peaks form. Set aside for folding into the cream cheese mixture.
  4. Make Cheesecake Mixture: In a separate bowl, beat softened cream cheese on medium-high speed for 2 to 3 minutes until light and fluffy. Add the peanut butter and continue beating until well combined.
  5. Add Sweeteners and Flavor: Beat in powdered sugar until smooth and no lumps remain. Then add vanilla extract and mix to incorporate evenly.
  6. Fold in Whipped Cream and Reese’s: Gently fold the whipped heavy cream into the cream cheese mixture until combined. Then fold in the coarsely chopped Reese’s candies carefully.
  7. Assemble First Cheese Layer: Spread half of the peanut butter cheesecake mixture evenly over the hot fudge layer in the baking dish.
  8. Add Second Graham Cracker Layer: Place another layer of graham crackers over the cheesecake mixture, then spread the remaining hot fudge sauce on top. Follow with the remaining cheesecake mixture and finish with a final graham cracker layer.
  9. Prepare Whipped Cream Topping: Whip 1 cup heavy whipping cream with powdered sugar and vanilla extract until stiff peaks form.
  10. Apply Whipped Cream: Spread the whipped cream topping evenly over the final graham cracker layer.
  11. Make Graham Cracker Crumble: In a small bowl, combine graham cracker crumbs, melted butter, and sugar. Mix thoroughly and sprinkle this crumble evenly over the whipped cream topping.
  12. Chill Cake: Cover the dish with plastic wrap or foil and refrigerate the icebox cake for at least 8 hours to set and allow flavors to meld.
  13. Serve: Optionally, top with extra chopped Reese’s candies before serving for added texture and flavor.

Notes

  • Use full-size Reese’s for best texture and flavor contrast; coarsely chopping them provides delightful peanut butter pieces throughout the cake.
  • Ensure the cream cheese is fully softened before mixing for a smooth filling.
  • Allow sufficient chilling time (minimum 8 hours) for proper layering and softness.
  • You can substitute hot fudge sauce with chocolate syrup if desired, but fudge sauce provides a richer flavor.
  • Store leftovers covered in the refrigerator and consume within 3-4 days for freshness.
  • If you prefer a firmer crunch, use more graham crackers in the layers.
