1 1/2 C graham cracker crumbs
1 lb (3 1/2 C) powdered sugar
1 1/2 C creamy peanut butter
1 C (2 sticks) real butter, melted
1 12oz bag chocolate chips (milk, semi-sweet, or dark, you pick!)
2 tsp shortening
In a large mixing bowl, combine graham cracker crumbs, powdered sugar and peanut butter and butter and combine. Press into a parchment lined 9x13 pan.
Place chocolate chips and shortening in a microwave safe bowl and heat in 30 second intervals, stirring after each one, until melted and smooth. Pour chocolate over peanut butter mixture and spread out evenly. Place pan in the fridge just until chocolate is set and then cut into bars.
