I got this recipe from my friend Karen (Veniceforever) on thenest.com. It's super easy and they are absolutely wonderful bars.
1 1/2 Cups Graham Crackers Finely Crushed
2 Cups Powder Sugar
8 Tblsp butter, melted
1 Cup Peanut Butter
1 1/2 Cups Chocolate Chips
Mix Graham Cracker Crumbs and Sugar, Add Melted butter and Peanut Butter to Mix.
Mix well place in 9x13 OR 9x9 pan (I used 9x9, b/c i wanted thick cookies)
Melt chips and spread over bars, place in frig until hard, leave at room temp for 15 minutes before serving.
I used Carmel kisses instead of chocolate chips and it was really good.
