To make these delicious peanut butter bars, you will need a jelly roll pan, or some kind of rimmed cookie sheet with at least a 1 inch edge. If you don’t have one on hand, you could use a large casserole dish, but may need to bake them for a bit longer.

I made all of these bars after doing an inventory of my fridge, freezer, and pantry. I realized I had way to much half-used food and decided to get creative. I made these yummy peanut butter bars with chocolate frosting (which were a total win) and a chicken dish in the crock pot (which was a total flop). Don’t worry, I only post the winning recipes on this blog. 🙂
