How to Make Chocolate Peanut Butter Bars

Step 1: Crush the Graham Crackers

This was my toddlers’ favorite part. Put the graham crackers in a zip-top bag, seal it, and let them smash away. Rolling pin, cup, tiny fists — whatever works.

If you’re not cooking with kids, you can also use a rolling pin or food processor. But honestly, letting toddlers help burns energy and keeps them entertained.

Step 2: Make the Peanut Butter Layer

Melt the butter, then mix it with the crushed graham crackers, powdered sugar, and peanut butter until smooth and thick. Press the mixture firmly into a parchment-lined pan.

(Pro tip: really press it down so the bars hold together.)

Step 3: Add the Chocolate

Melt the chocolate chips until smooth, then spread evenly over the peanut butter layer.

Step 4: Chill & Slice

Refrigerate until firm, then slice into bars and enjoy.

Tips for the Best No-Bake Peanut Butter Bars

  • Use creamy peanut butter for the smoothest texture
  • Line your pan with parchment paper for easy removal
  • Chill before slicing for clean cuts
  • Store leftovers in the fridge (if there are leftovers)
