Another favorite from when I was a kid. These are similar to the Reese's ® peanut butter cups. The promise of these for dessert always helped persuade me to eat more of my dinner! Might work with your kids too!

2 cups crushed graham crackers
1 cup melted butter
1 cup peanut butter
2 cups powdered sugar
6 ounces chocolate chips

Mix together above ingredients except chocolate chips. Press into 9 x 13 inch greased pan. Let set in refrigerator to cool. Melt chocolate chips and spread over top for frosting. Cut into bars.
