I loved Rice Krispies when I was a kid. They really did go snap, crackle, and pop when you added milk! Mine came in a 10 pack of cereals. My favorite was Sugar Smacks, but Kellogg's Rice Krispies were #2. My mother's rule was that if you wanted the Variety Pack, you had to eat them all. The small individually boxed cereals came in cardboard boxes that you opened and poured the milk directly into (another 50s 'time saver'). Alas, there weren't any chocolate cereals in the pack. Kellogg's Cocoa Krispies had not hit the market. When it did come out, it was a natural that there would be recipes similar to Rice Krispie Treats.
So here's a "Chocolate" Retro Ad & Recipe for Cocoa Peanut Logs! Enjoy!
