Our Fiddle Diddles — also known as Haystacks or Spider Cookies — are a no-bake classic made the old-fashioned way. We blend rich cocoa, oats, margerine, and sugar into a warm, glossy mixture, then drop each cookie by hand so they set into their signature rustic “haystack” shape. Chewy, chocolatey, and nostalgic, they’re the kind of treat everyone remembers from childhood.
