Every December my kids fall back in love with anything Grinch green. So we made a batch of Grinch moon sand: soft, crumbly, perfectly green and so fun to squish.
It’s colored with matcha powder instead of food coloring, and a sprinkle of red hearts makes it extra festive.

Is it taste safe?
A nibble won’t hurt, but it’s for playing, not snacking. Matcha has a little caffeine, and raw flour can carry germs. For kids who mouth everything, heat-treat the flour first: bake it at 350°F for about 5 minutes, then cool.
Grinch Moon Sand Tips
- Too dry? Add a tiny drizzle of oil.
- Too sticky? Add a spoonful of flour.
- Storing it: Keep it in an airtight container at room temperature for several days. Revive it with a splash of oil.
- Toss it if it smells off.
- Keep it on the tray: It travels!
