To decorate a cupcake with edible glitter: Choose the right type of glitter: Edible glitter is available in a variety of shapes, sizes, and colors. Choose a glitter that complements the cupcake's flavor and theme. Prepare the frosting: Frost the cupcake using a spatula or a piping bag. You can use any flavor of frosting, such as buttercream, whipped cream, or cream cheese. Apply the glitter: Once the frosting is applied, sprinkle the edible glitter evenly over the top of the cupcake. You can also use a brush to apply the glitter if desired. Let it set: Allow the glitter to set for a few minutes before serving the cupcake. This will prevent the glitter from rubbing off onto fingers or clothing. Note: It is important to use only edible glitter as non-edible glitter can be harmful if ingested. Additionally, always check the label to make sure the glitter is food-safe.
