There's quite a few ways to frost cupcakes. The most popular way is to use a piping bag and piping tip, as it creates the most decorated version. If you don't have a piping bag or tip, you can simply add frosting to a zip-top bag and snip off the corner for the desired thickness.u003cbr/u003eu003cbr/u003eYou can also spread the frosting on with a knife or spatula. Finally, one of my favorite methods is to use a cookie or ice cream scoop to add a dollop of frosting on top of each cupcake!
