step one: bake your cookies
Roll out your cookie dough a little thick (about 1/4 inch), cut out circles, place on parchment paper lined baking tray and insert lollipop sticks about half way. Pat back in shape if needed. Bake according to the recipe (see the link above) and let cool.
step two: decorate your cookies
Prepare a frosting bag with 4 tip and fill with white frosting. Tie bag closed with a rubber band. Pipe a circle on the cookie. Let set a good 1/2 hour. Mix some white frosting with enough water (start with only a few drops) to thin to the consistency of syrup. Pour a little in the center of the circle and spread to the edges with the back of a spoon or small spatula. Let set another 1/2 hour at least.
Prepare a frosting bag with 4 tip and fill with yellow frosting. Close bag with rubber band. Pipe a circle on top of the white circle. Let cookies sit a good hour and draw the clock face (with the hands pointing to almost midnight) with your marker.
