Servings: 4 rocks
Ingredients
Instructions
- Add the coffee grounds, flour, salt and about half of the brewed coffee to a bowl and mix together. Add the rest of the brewed coffee in slowly, as needed, to form a slightly sticky dough.
- Form the dough around your dinosaur and shape it to look like a rock. To make it look realistic, give it an uneven, or rough texture. You can also leave a part of the dinosaur sticking out if you’d like.
- Place them on a baking sheet lined with parchment paper and bake in the oven at 200º F for 1-2 hours, until the dough is dried out. The cooking time will depend on how big your rocks are as well as how much moisture is in the dough. If you don’t want to bake them, you can also set them outside to dry in the sun.
- Once they are dry, let your kids break them open with a hammer. I hid them in the garden and let my son “discover” them first. ????

Notes
- You can use any kind of small, hard plastic dinosaur toys you'd like in these fossil rocks! I chose to use these dinosaur skeletons to make the fossils a little more realistic.
- Hard plastic melts at different temperatures, but in general the plastic dinosaurs should not melt at 200º F. If you don't want to risk the plastic melting, dry the fossil rocks out in the sun.
