Ingredients

Ingredients: powdered sugar, graham cracker crumbs, butter, peanut butter, and semi-sweet chocolate chips.

Creamy peanut butter: Look for a smooth peanut butter. If you are using a natural peanut butter, make sure to stir it well before using. Used in both the base and the chocolate layer.

Unsalted butter: Melted.

Powdered sugar: Sifting it before mixing can prevent any lumps in your bars.

Graham cracker crumbs: You can crush your own graham crackers or buy pre-made crumbs.

Semi-sweet chocolate chips: You can swap for dark chocolate if you prefer.

How to Make

Line a 9x9-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later.

In a medium-sized mixing bowl, combine the melted butter with 1 cup of creamy peanut butter, stirring until the mixture is smooth. Gradually add the powdered sugar and graham cracker crumbs, mixing until everything is well combined and a thick dough forms.

Tips & Tricks

Crush graham crackers: If you don’t have pre-made crumbs, place graham crackers in a zip-top bag and crush them with a rolling pin for a quick method.

Microwave in short intervals: When melting the chocolate, use 30-second intervals and stir well between each to prevent overheating and burning.

Use a larger pan for thinner bars: If you prefer thinner bars, use a larger pan and adjust the chilling time accordingly.

Cutting technique: Use a sharp knife dipped in warm water to cut the bars cleanly, preventing any crumbling.
