It's really dangerous knowing you can make Homemade Reese's Bars at home. I mean chocolate peanut butter bars are one of my favorite things. Sure, I love a Reese's Peanut Butter Cup too but bars are so much easier to make.
In a medium bowl, stir together graham cracker crumbs, confectioners' sugar, peanut butter and melted butter. Press firmly into the bottom of a 9x13 inch pan.
Melt chocolate chips and peanut butter in the microwave, stirring occasionally. Spread melted chocolate over the crumb crust. Chill for one hour and then cut into squares.
