TIPS:
*Be sure you measure accurately here. Too little milk, and the glaze won't spread nicely. Too much milk, and it will be thin, spotty and develop splotches overnight.
*Once the glaze has hardened, you can color on it with foodsafe markers, or you can pipe another color over the top with Royal Icing. You can sprinkle sugar on top of the wet royal icing for a sparkly effect.
