First, Make The Bars:

1. Prep Your Pan. Grease an 8×8 or 9×9 metal baking pan or line with parchment paper (my preference).
2. Crush The Graham Crackers. If you haven’t already, crush the graham crackers into fine crumbs in a food processor or a zip-top bag with a rolling pin. (You don’t want any large pieces for these bars.)
3. Assemble Bar Ingredients. Add the graham cracker crumbs to a large bowl, along with powdered sugar, and salt. Add the peanut butter.
4. Melt The Butter. Next, melt the butter in a microwave-safe bowl in 15-20 second increments until it’s fully melted. (You can also do this on the stove in a saucepan over medium heat) Pour the melted butter over the graham cracker crumbs, sugar, salt, and peanut butter. Stir to combine until the mixture is smooth and uniform.
5. Pat It Out. Transfer the peanut butter mixture to your prepared pan and gently spread it into an even layer or pat the mixture out with your hands. (Using a little bit of parchment paper can make this easier!)

Then Make The Chocolate Topping:

1. Melt Peanut Butter & Chocolate Chips. Add 2 Tablespoons peanut butter and the chocolate chips to a microwave-safe bowl and gently melt in 20-30 second intervals until the mixture is smooth.
2. Pour & Spread. Next, pour the melted chocolate mixture over the peanut butter filling and smooth into an even layer.
3. Chill the bars until set, about 2 hours or so.
4. Serve & Store. Cut into squares or bars with a sharp knife and enjoy immediately. Store leftovers in an airtight container in the fridge up to 1 week. (You can also freeze them up to 2 months)
