Learn how to make FUN treasure stones that are hard like rocks that kids can easily break open to find a treasure inside! Get the easy treasure stone recipe and step-by-step instructions.
There’s just something magical about creating a cool kids activity out of basic ingredients you already have. These treasure stones I made for my son’s jungle safari birthday party are just that!
What are Treasure Stones?
What Toys Can You Bake Inside a Treasure Stone?
- plastic animals
- kids rings and necklaces
- toy cars
- and so much more!
The sky is really the limit. Most items are protected as they bake in the oven by the dough that surrounds them.
Be sure to keep an eye on your treasure stones while they bake, to be safe.
What Do You Do with Treasure Stones?
- Turn the stones into dinosaur eggs for a dinosaur dig party like we did.
- Treasure stones can be made to look like cannonballs for a pirate party.
- Let the kids go on a hunt for the “rocks” in the backyard.
- Pass them out as party favors at the end of a party.
Kids (and adults) of all ages will love breaking open their toys and seeing what’s inside!
DIY Treasure Stones
- 1 cup flour
- 1 cup used coffee grounds (I get them for free from Starbucks since I don't drink coffee)
- 1/2 cup salt
- 1/4 cup sand (You can use beach sand, playground sand, sand from Home Depot, or even cornmeal if you don't have any sand)
- 3/4 cup water
- Small toys and prizes (Marbles, plastic animals, fake or real coins, and plastic jewelry are all great choices!)
- Preheat the oven to 175 degrees F. Combine all of the dry ingredients, then slowly add in the water and stir until the mixture becomes a dough. If the dough is still too wet, add some flour or sand to get the right consistency. The dough should be nice and firm, and not too wet.
- Roll a piece of dough into a ball, add a toy or two to the middle, then roll the dough back into a nice, smooth ball.
- Place the balls of dough on a foil-covered baking sheet, and bake for 45 minutes. Be sure to let them cool completely before letting kids break them open.
