This Gingerbread Icing recipe is the easiest ever. With just 2 simple ingredients and about 2 minutes, you can have spreadable, pipable icing for your favorite gingerbread cookie recipe.
In a small bowl, stir the powdered sugar with 2 tablespoons of milk. Add more, a little at a time, until smooth, and it drizzles into thick ribbons that hold their shape for several seconds before dissipating. Tint with gel food coloring, if desired.
Spread or pipe onto cooled cookies. Add sprinkles while the icing is still wet. Allow to dry for several hours before stacking.
Notes
For outlining, keep your icing extra thick so it holds shape.
For flooding, thin the icing by adding milk a few drops at a time.
If the frosting crusts over in the bowl, stir until smooth.
Add sprinkles and candies while the icing is wet so they stick.
Some sprinkles or candies may bleed into the icing -- test them in a little water first.
Cool baked cookies completely before frosting them.
