Ingredients
  

Main Ingredients

  • 2 cups finely crushed graham crackers (about 28 square crackers)
  • 2 cups powdered sugar
  • 1 cup butter, melted
  • 1 1/4 cups creamy peanut butter, divided
  • 1 1/2 cups semisweet chocolate chips
  • 1/4 cup chopped unsalted roasted peanuts (optional)

Optional Ingredients

  • 1 teaspoon vanilla extract adds bakery-style warmth
  • 1–2 tablespoons crushed pretzels for extra crunch in the base
  • 1 tablespoon coconut oil helps chocolate topping slice more easily
  • Flaky sea salt a light sprinkle on top is amazing

Instructions
 

Preparation

  • Line a 9×13-inch pan with parchment paper, leaving overhang on two sides for easy removal (optional).
  • Measure all ingredients before you start.

Mixing / Assembling

  • In a mixing bowl, combine graham cracker crumbs, powdered sugar, melted butter, and 1 cup of the peanut butter.
  • Stir until the mixture looks evenly moistened and thick, like soft dough.
  • Press the mixture firmly and evenly into the bottom of the pan.
  • Chill the crust for 30 minutes to set.

Making the Topping

  • In a microwave-safe bowl, combine chocolate chips and the remaining 1/4 cup peanut butter.
  • Microwave on High in short bursts, stirring every 15 seconds, until smooth.
  • Pour the chocolate mixture over the chilled crust and spread evenly.
  • Sprinkle chopped peanuts on top if using, pressing them lightly to stick.

Chilling

  • Cover and chill for at least 1 hour before slicing.
  • For clean cuts, let the pan sit at room temperature for 5 minutes before slicing.

Notes

Press the crust firmly for best texture. A sprinkle of flaky salt enhances chocolate flavor. Avoid overheating chocolate while melting.
