The Mr. Peanut Peanut Butter Maker was an unusual late 1970’s toy; although it first appeared in 1967, I had some variation of it around 1977 or 1978, when I was in kindergarten or the first grade. I loved it beyond reason. (I was bizarrely fixated with peanut butter at that age.)
As a few toy collectors have pointed out online, what’s interesting about this product is that it was both a child-safe toy and a marginally functional appliance — you could indeed make peanut butter with it, albeit very slowly. You just poured the peanuts in and cranked away. I honestly can still remember how it tasted, without the added oil and sugar of store-bought peanut butter. It wasn’t as smooth, but it was damned good.
