Ingredients

For Cookie Layer

  • 6 oz graham crackers or digestive biscuits
  • 4 tablespoons unsalted butter melted

For Crunchy Chocolate Layer

  • 1 cup Honey Bunches of Oats or crispy cereal
  • 1/2 cup creamy peanut butter
  • 3 oz semi-sweet chocolate melted

For Peanut Butter Mousse

  • 4 oz cream cheese softened
  • 1/2 cup powdered sugar
  • 1/2 cup creamy peanut butter
  • 1 cup heavy whipping cream cold

For Chocolate Ganache

  • 1 cup semi-sweet chocolate chips or chopped chocolate
  • 1/2 cup heavy cream

Instructions

Prepare Pan

  • Line an 8x8-inch pan or loaf pan with parchment paper, leaving overhang for easy removal.

Cookie Crust

  • Crush graham crackers into fine crumbs.
  • Mix crumbs with melted butter until evenly combined.
  • Press mixture firmly into bottom of pan. Refrigerate.

Crunchy Chocolate Layer

  • Stir melted chocolate and peanut butter together until smooth.
  • Fold in cereal.
  • Spread over chilled crust and refrigerate.

Peanut Butter Mousse

  • Beat cream cheese until smooth.
  • Add powdered sugar and peanut butter. Beat until creamy.
  • In separate bowl, whip heavy cream to stiff peaks.
  • Fold whipped cream into peanut butter mixture gently until fluffy.
  • Spread over cereal layer. Refrigerate 3 hours or until firm.

Ganache

  • Heat heavy cream until hot but not boiling.
  • Pour over chocolate. Let sit 1 minute. Stir until glossy and smooth.
  • Spread ganache over mousse layer.

Finish

  • Sprinkle chopped peanuts or flaky salt on top if desired.
  • Refrigerate 30 minutes to set.

Notes

  • Use regular creamy peanut butter for the best texture. Natural peanut butter can separate.

  • Store refrigerated up to 5 days.
  • Bars can be frozen for up to 1 month.
  • Swap graham crackers for Oreos or vanilla wafers if desired.
