How Do You Fill Cupcakes With Icing?
To fill cupcakes with icing, you can insert the frosting into the cupcakes using a piping bag or a zip-top bag with a small hole cut into one corner. Push the tip just into the center of the cupcake and gently squeeze the bag until the cupcake begins to bulge slightly. Move the tip slightly off-center and continue piping until the cupcake is filled with the desired amount of icing. Repeat with the remaining cupcakes.
