FatBoy® is America’s #1 Ice Cream Sandwich—but the story starts long before the first sandwich was ever made.
In 1925, Casper Merrill began crafting frozen novelties using cream from his family’s milk cows in northern Utah. He launched his first creation—the “Casco® Nut Sundae”—at a local 4th of July celebration. From those humble beginnings grew a legacy of bold, creamy indulgence. Soon after, Casper developed his original FatBoy® Ice Cream Sandwich, a much larger than usual ice cream novelty.
