No Bake Chocolate Peanut Butter “Lunchroom” Bars


These no bake chocolate peanut butter “lunchroom” bars were a favorite treat to many of us who lived long enough ago that lunchroom food was made from scratch and often quite yummy (just like these bars).

For most of us who lived “back in the day” when school lunches tasted like home cooking, these yummy chocolate bars will stir fond memories.

Other than the heavenly lunchroom rolls that prompted most students to ask for an “extra,” these chocolate peanut butter bars were probably one of the most popular lunchroom menu items. Since peanut butter was a government commodity and in plentiful supply, these treats were served often.

There are several versions of this recipe–some using brown sugar, some using white, some using graham crackers, some not, and some using peanut butter in the icing and some using only chocolate. I’ve tried most, and these are my personal favorite. They taste as close to a homemade Reese’s Peanut Butter Cup as anything I’ve ever eaten.

The following recipe makes a large amount, so I frequently half the recipe and make in a 8 x 8 square pan. To make the bars easier to cut squares, I always line the pan with parchment paper. When the mixture is firm, remove all at once by lifting the parchment paper. Cut into squares, and store in an airtight container.

If you make these, please let me hear back! If you recall a fond lunchroom treat, please share your bit of nostalgia:-) As always, thanks so much for stopping by. Be blessed, and stay savvy!!!
