Line an 8″x8″ or 9″x9″ pan with aluminum foil. Set aside.

In a medium-sized, microwave-safe bowl, microwave the butter for 1 minute or until the butter is completely melted. Add in 1 cup of the peanut butter, graham cracker crumbs, and powdered sugar. Stir until completely combined.

Spread mixture evenly in the prepared pan. Place in the refrigerator.

In a small bowl, microwave 2 tablespoons of peanut butter with the chocolate chips until melted, about 30-45 seconds (note: this depends on the strength of your microwave). Stir until smooth. Spread over peanut butter layer.

Chill until firm, about 1 hour.

Cut, serve, and enjoy!
