1 batch of sugar cookie dough (store bought or homemade recipe here)
1 batch of royal icing (recipe here)
Black food coloring or black food marker
- Prepare cookie dough according to the recipe and roll it out into a large rectangle on a floured surface.
- Measure how large you want your squares to be and cut even tiles with a sharp knife. Bake in a 350 degree oven for about 9 minutes.
- Prepare the plain white royal icing and load 3/4 of the icing into a plastic squeeze bottle or piping bag to flood the backgrounds of the tiles. Reserve the rest of the icing in a small bowl covered with a damp paper towel.
- When the white backgrounds are completely dry, dye the remaining royal icing black and load it into a decorating bag with a very small round tip. (You could also skip this step and just use a black food marker!) Pipe the letters and numbers and allow the icing to dry for at least 12 hours before handling them.
