A thick and gooey frosting that's perfect for assembling gingerbread houses! It's still fluffy enough to decorate with but sticky to glue the gingerbread together.
In an electric mixer fitted with the whisk attachment, beat egg whites and cream of tartar together.
When the egg whites are whipped to firm peaks, turn the mixer to low and spoon in the powdered sugar.
Continue adding in the powdered sugar until it's gone, then turn the mixer on high to whip again.
Once it becomes fluffy (only a few minutes) it's done. It should be sticky, fluffy and thick!
Divide the frosting into different bowls and add the desired amount of food coloring to each bowl. Whatever colors you want.
