No bake peanut butter bars are basically like buckeye bars, but with graham cracker crumbs mixed in. They taste amazing and are really easy to make. They may just become your new favorite no-bake bar!
In a large mixing bowl, beat room temperature butter until smooth. Add 1½ cups of the peanut butter and mix until combined.
Stir in the powdered sugar and vanilla.
Add the graham cracker crumbs and mix until uniform. The mixture will be a little bit crumbly.
Dump the peanut butter mixture into a lightly greased 9×13 pan and press to form a cohesive layer of peanut butter.
Put remaining ½ cup of peanut butter and chocolate chips in a medium glass bowl. Microwave on high in 30 second increments until you can stir the mixture smooth.
Once the chocolate mixture is melted and smooth, spread over the peanut butter layer. Top with chopped peanut butter cups if desired and refrigerate until set.
They are the easiest to cut and serve while still slightly chilled, but taste best at room temperature. They will get soft in the summer heat but still taste amazing!
Notes
We use salted butter for these bars. If you use unsalted, you may want to add a pinch of salt or even a heavy pinch if you like more salt in you sweet and salty treats.
