Chewy peanut butter bars topped with more peanut butter and a creamy chocolate frosting are perfect for that chocolate peanut butter craving you have been having. You can whip these cookie bars up in under and hour and have a sweet treat to nibble on all weekend.
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. 🙂
I also had a super cute 4-year-old taste tester patiently waiting for me to finish taking pictures so he could try one of these decadent peanut butter bars.
And this is when the sugar kicked in about 10 seconds later. Ha!
I hope you enjoy them as much as he did!
