Found on line, and this PB and chocolate addict had to save, other recipes that use graham crackers crushed into the bar, and while I’m sure that is delicious, this recipe has no crumbs. It’s melt in your mouth peanut butter, sugar, and butter! NOTE: recipes says "If you don’t want your chocolate to “crack” when cutting your bars, don’t refrigerate these bars. And cut them as soon as the chocolate sets (about 30 minutes room temperature)"
