Retro School Cafeteria Peanut Butter Bars
It's taken me a while to find this recipe. There are many versions of "the peanut butter bar" but, I believe this recipe comes the closest to what I remember eating in the 1960's (via our elementary school lunchroom). Boy those ladies could really cook back then!
Recipe Summary test
You can use margarine instead of butter.
Refrigerating bars before frosting works best in my opinion.
