If you don't want to spend a lot of time mixing colors and piping, you can still make some pretty cute cookies using edible markers.
The markers are especially nice for tiny details that are difficult to add with a piping bag. To make these cute Christmas cookies, I flooded the cookies with blue royal icing and immediately added some dots for snow. After that dried, I used the same white icing that I used for the snow to add snowman and tree shapes. Then you just need to wait for the icing to dry completely before you can go to town decorating with edible markers.
The edible marker method is really the easiest way to decorate cookies and the perfect project for young children.
My favorite markers to use are from AmeriColor. The colors are vibrant and not translucent. They are available online and in specialty baking shops. Once you have the markers, you'll find lots of other uses for them besides cookie decorating. Who wouldn't love to find a funny faced apple in their sack lunch?
