There’s just something about peanut butter icing that immediately takes me back to third grade at my small elementary school. Always a peanut butter lover, I couldn’t wait until I saw that we were having peanut butter cake with peanut butter icing on the lunch menu that would come out for the next week. You see, we had a small, weekly newspaper that was released each Thursday and in it would be the lunch menu for all of the local schools for the upcoming week. Yes, really. I loved that little paper. As a matter of fact, when I was in high school, I worked for the paper one year. I did a few odd-ball jobs there, but also was responsible for writing the copy for local sports coverage for the editor to review. Oh my, my, my. How in the world they ever let me do that, I’ll never have a clue.

Anyway, back to the peanut butter icing. One of the ladies that worked in the lunchroom was famous for her peanut butter cake with peanut butter icing. Not frosting, mind you. Frosting is a fluffy confection while icing is a bit thinner and pours onto a sheet cake, coating it like a glove. And her peanut butter icing was out of this world. She’d make it on brownies, blondies and her peanut butter cake. Heavens, I loved that stuff. And I would be sure to look at the newspaper sometime before Sunday evenings so that I could be sure to tell my Mama which days I wanted to eat lunch in the lunchroom versus take lunch from home. All because of her cake.

I doubt seriously that peanut butter cake with peanut butter icing is still served in many schools and I’ve not seen a school menu printed in the newspapers around here in more years than I care to count. So, here’s to the good ole days of small town newspapers and looking forward to the lunch menu!
