Have you ever been halfway through flooding a cookie and suddenly had to walk away?
That used to happen to me constantly when I first started decorating cookies with a newborn at home. By the time I came back, the royal icing had started to crust, and trying to blend fresh icing into it usually made a mess.
So I came up with what I call my Cookie Time Machine.
It’s a simple setup using an airtight container, a damp paper towel, and a small cookie turntable. The enclosed space helps slow down the surface drying so you can step away briefly and come back to icing that’s still workable.
What You Need
- Airtight food-storage container
- Small cookie turntable
- Paper towel
- Spray bottle with clean water
Place the lid of an airtight container upside down on your work surface. Lay a paper towel on the lid and lightly dampen it with clean water. Set your cookie turntable and cookie on top. If you need to walk away, place the body of the container over the cookie. The humidity inside helps keep the royal icing from drying and crusting while you’re gone.
Important: Never spray water directly onto your royal icing.
In the video, I leave the cookie for more than ten minutes, come back to finish flooding it, and even add a wet-on-wet design to show that the icing is still workable.

It’s a tiny trick, but it can save a half-flooded cookie when life interrupts your decorating.
