Step 1

Line a 11×7 baking pan with aluminum foil/parchment paper. Generously spray with nonstick spray. Set aside.

Step 2

Melt the butter and peanut butter in a large saucepan over low to medium heat.  Add the marshmallows and constantly stir until they are completely melted. Mixture will be thick. Remove from heat and add in Rice Krispie cereal. Mix together well. Press mixture into prepared baking pan. I used a spatula sprayed with nonstick spray to make the sticky mixture easier to press down. Top peanut butter layer with mini Reese’s cups. Set baking pan aside.

Step 3

Melt the butter in the same large saucepan over low to medium heat. Add the marshmallows and constantly stir until they are completely melted. Remove from heat and add in Cocoa Krispies cereal. Mix together well. Press mixture on top of the peanut butter layer. Press chocolate chips on top of chocolate layer and allow to set for at least 30 minutes.

Step 4

Cut into 24 squares.
