My friend Jenny shared this recipe with me many years ago and it is a family favorite...we also love to makes these to share. Not really sure who Krista is, but I know I like her!
Krista's Peanut Butter Squares
Mix together in a bowl:
3 1/2 cups powdered sugar
1/3 pound graham crackers, crushed
1 cup peanut butter
2 sticks of melted butter
Spread in a greased 9" x 13" pan and chill until set. Melt 2 cups semi-sweet chocolate chips in the microwave (stirring frequently) and spread over chilled peanut butter mixture. Use the back of a butter knife to score the chocolate into serving-sized squares to make cutting easier and then chill until set.
And if that isn't enough chocolate/peanut butter goodness to make you crazy, try this recipe from Cocoa over at Chocolate on my Cranium. Wowsa.
