Decorate There is really not much to decorating cupcakes, especially in the eyes of your admiring children. Just a dollop of frosting is artistic enough for them! Here are a few simple tips that will help you decorate your holiday cupcakes.
Sprinkles - Open the container, hold frosted cupcake upside down and dip into the sprinkles. Another option is to roll the outer edge of the cupcake in the sprinkles.
Sugar - Using decorator sugar, follow the same instructions as the sprinkles. The green sugar creates a sparkling blanket effect that is very eye catching! It almost appears to be velvety.
Decorator Gel - Use gel to draw on a shamrock. Shamrocks are simple, think of them as three heart shapes, all three meeting in the middle with their bottom tips. Then simply add a stem.
Combinations - Roll the edges in sprinkles and dip the center in sugar, or vice versa. Or dip edge and decorate center with gel.
Be sure to store your cupcakes in a tightly covered container so they do not harden or go stale. That is, if they last that long!
