The Original. Vanilla ice cream bars dipped in chocolate & roasted peanuts. It all began, way back in 1925, Casper Merrill took the milk and cream from the family milk cows and made the first, the original, ice cream nut sundae on a stick. He made those first nut sundaes in a ten gallon mil can and sold them at the local 4th of July celebration. Soon after, Casper developed hid original Fat Boy Ice Cream Sandwich, a much larger than usual ice cream novelty. Everyone who tried those first Nut Sundaes and Fat Boys enjoyed them so much they wanted more. So, Casper began making them on a large scale and soon people all over the entire Intermountain West were enjoying them. The original ingredients and recipe have changed very littler over the years. Today, folks all across the country are eating and enjoying Nut Sundaes and Fat Boys just as much as those who enjoyed the first ones during the 4th of July celebration of 1925.
