This recipe is perfect for a bake sale or potluck. It's pretty easy too. Mix together crushed pretzels, melted butter, powdered sugar and peanut butter. Press into a greased pan. Melt chocolate chips and peanut butter together in a microwave. Once melted and smooth, pour the combination over the mixture in the pan. Chill for an hour to set, then slice into bars.
