Cake crumbs are small pieces or fragments that break off from a cake during cutting or serving. They can vary in size and texture, depending on the type of cake and how it was baked. Cake crumbs are often a natural byproduct of enjoying a cake, whether it's a homemade dessert or a store-bought treat. In baking, cake crumbs can also be used creatively. They can be repurposed in recipes like cake pops or as a topping for ice cream and desserts. Additionally, some bakers use crumbs to create a decorative layer on cakes, adding both flavor and visual appeal.
