I absolutely loved School Lunch Peanut Butter Bars growing up. When I did a project for the Lunch Ladies in the School District where I live some years ago I literally begged them for the recipe. They were kind enough to supply me with the real deal.

I love peanut butter bars! They are probably the most addicting thing in the world. For those that are looking for a frosting recipe-the best I've found (that matches the old school lunch bars) is the one on the back of the Hershey's cocoa can. I also add a couple drops of butter flavoring from the candy making aisle. It gets rid of that weird, missing something taste.

Not sure if this will help, but other sights use this recipe for the peanut butter bars:<br/>1/2 c. salted butter<br/>2 Tbsp cocoa powder (or more, depending on your chocolate craving)<br/>1/4 c. milk (2% or whole)<br/>1 tsp vanilla<br/>3 1/2 c. powdered sugar

These were easy to make but I was unsure what size of pan to use so I ended up using a 9x13inch pan and let them cook for an additional 10 minutes. I ended up sprinkling on milk chocolate chips on top of the peanut butter and then putting it back in the oven for a few minutes. then they were easy to spread over the top. my kids loved these. Thanks for the recipe
