Which method can be used to ice cupcakes?

Dipping the tops in icing is a popular and effective method for icing cupcakes. This technique allows for an even coating and can create a smooth, glossy finish that enhances the visual appeal. Dipping gives the cupcake an enticing layer of icing without the need for extensive tools or techniques, making it accessible for both experienced bakers and beginners.

The other methods, while they can be used, may not provide the same results. Spreading icing with hands could lead to uneven application and potential messiness. Piping icing onto the sides may not cover the entire surface effectively. Pouring icing over cupcakes could create a pool of icing at the bottom rather than an even layer on top, which can lead to overly sweet or soggy edges. Thus, dipping is the most efficient and visually pleasing option for icing cupcakes.
