Why don't jimmies melt?

Jimmies, which are a type of chocolate sprinkles, don't melt easily because they are made from sugar, cocoa powder, and other ingredients that help them maintain their shape. They have a low moisture content and are designed to withstand heat, making them stable at typical dessert temperatures. Additionally, the sugar coating helps to insulate the inner chocolate, preventing it from melting quickly. This stability allows them to retain their texture when used as a topping on desserts.
