christmas sprinkles 50g Sprinkles are used to top all sorts of desserts, including ice cream, cookies, cakes, and doughnuts. The only requirement is that the dessert has a somewhat sticky surface—like frosting—for the sprinkles to adhere to. They’re typically added right before serving as a decorative touch, but they are sometimes included in the baking process. For example, you mix sprinkles into the batter for confetti cake. As the cake bakes, the sprinkles dissolve and create colorful dots that look like confetti.
