It's the perfect party activity.
Put out bowls of frosting (several different colors if you want) and little plastic spreaders with an assortment of other fun cake toppers -- sprinkles, gumdrops, crushed up cookies, or other candies.
Not only will it save you some time and some pride (if you're inviting the supermom crowd), the kids will absolutely love it. It's a great party activity that will keep the guests entertained -- and fed.
You can also up the fun factor and make the kids feel like pros by setting out this Kuhn Rikon decorating kit -- they'll love squeezing the frosting from the different tubes.
If you'd rather decorate your child's cake or cupcakes yourself (or have a bakery do it), you can still use the decorating kit -- or just the idea -- and have party guests decorate cookies instead. Tie the cookies into the birthday party theme (make truck-shaped cookies, dinosaur-shaped cookies, ballet slippers, sailboats, etc.).
Have you ever had a party where the kiddie guests decorated their own cupcakes or cookies? How did you set up the activity?
