Ingredients

Instructions

  1. Line an 8×8-inch pan (for thicker bars) or 9×9-inch pan (thinner bars) with parchment paper or foil. Set aside. Melt butter in the microwave, then set it aside to cool to room temperature. (Hot butter melts the sugar and makes these bars greasy.) Crumble graham crackers into a blender or food processor and blend to get crumbs. Alternatively, add crackers to a gallon plastic bag, seal it without air, and crush crackers to crumbs with a frying pan, rolling pin, or meat mallet (see note 3).

Chef's Notes

Note 1: Any creamy and thick peanut butter will work; I love Skippy® Creamy Peanut Butter. I don’t recommend a natural peanut butter that needs stirring—it will make the bars greasy.
Note 2: Use milk chocolate for a sweeter dessert or semi-sweet or dark chocolate for a less-sweet treat. Stick to whatever chocolate you like best or a combination. I like milk and semi-sweet chocolate mixed (half and half) or plain milk chocolate best! The better the quality of chocolate, the better the flavor of these bars will be.
Note 3: To ensure there aren’t large chunks of graham crackers in the bars, which will affect the texture, blend the graham crackers until they are crumbs. Add any large pieces that didn’t blend completely back into the blender and blend again.
Storage: Cover leftover bars tightly and refrigerate for 5–7 days. To freeze, wrap each bar individually in plastic wrap and store them in a freezer-safe bag or container for up to 3 months. Thaw bars overnight in the fridge.
