Sometimes the most simple designs become favorites. Here is a design made for the first timer. My inspiration came from a large round Christmas platter I bought at Target after the holidays last year (with matching red tins). Start with the cookie. Sugar Cookie Recipe post is here.
You don't have to use a decorator bag or piping tips with royal icing. You can use a can of vanilla frosting and spatula. Add black food coloring to the icing or frosting and spread a thick line down the center of the cookie for the belt. Sprinkle with black sanding sugar. Pipe and fill the other two sides with red royal icing or spread red frosting and sprinkle with red sanding sugar.
If you are using royal icing, let the black with sugar dry for a while and then add the red icing. If the black icing is still wet when you sprinkle red sanding sugar, the red will stick in the spaces not covered by the black. Sanding sugar is very forgiving. You can push and/or pat the sugar to reshape the edges. Pipe a white rectangle belt buckle and sprinkle with white sanding sugar.
Place a silver jimmie sprinkle on the buckle. Done.
The Santa Belly Cookies are a cookie design that kids can do with very little help from you.
If your kids are anything like my kids, they like to be able to do it all by themselves.
