DIY Make your Own Dinosaur Egg Dig Tutorial - such an easy recipe to make your own dino eggs using coffee grinds! Perfect for birthday parties and hands on Montessori activities.

My son had will be having a Fossil / Dinosaur Birthday Party in a few months and I made these mini DIY dinosaur dig kits to send home with the kids as party favors! They were incredibly easy to make. When I was researching how to make these I stumbled upon several different “recipes” to create these DIY Dinosaur Eggs digs and so I decided to make two different recipes to see which one was best for making a large amount of these! I will include both recipes below but my consensus was that they both look and feel about the same in the end, but the Recipe 2 was a TON stickier and harder to work with when creating them! So if you want to make your own I highly recommend using Recipe 1!


1 cup used coffee grinds
1 cup flour
1/2 cup salt
1/4 cup sand (we used yellowed art sand)
3/4 cup water

Mix all of the dry ingredients together and then add 1/4 cup water at a time.


1 cup flour
1/2 cup cold coffee
1 cup used coffee grinds
1/2 cup salt 

Mix everything together!

Once you’ve mixed your recipe together flatten a chunk of dough out in your hand and just place your dinosaur or other treasure inside for the kids to later dig out and find! (We bought a big bag of small dinosaurs for under $10 on Amazon that were the perfect size.) Then roll the rest of the dough right over your toy to form an egg or rock.

Here are both of mine – one “egg” in each different recipe so that you can see what they look like. Now there are 2 different ways you can harden your rock. You can either bake them in the oven at 150* for about 20-30 minutes or you can leave them on a baking tray to air dry for about 2-3 weeks.

If the eggs are soft inside (about 1 week later) the kids should be able to just break them open with their hands. A great idea for younger kids! If the eggs are hard you can use a hammer (even a toy wooden hammer!) or other blunt object to crack them open.

We opened this one after air drying for 5 days and it was still soft inside but this is what it will look like when the kids break open their dinosaur eggs!

My boys dug their out and immediately started playing with their toy dinosaurs! It was a HUGE HIT!

    Love the dinosaur eggs you linked up at Favorite Friday at I’m Not a Trophy Wife!
    I just pinned and put on my FB page/notatrophywife

    Haven’t tried this yet but wanted to say THANK YOU for a couple of comparisons in this post. There are a few variations on dino eggs out there and none of the blogs I’ve read so far actually tell you information about the outcome and consistency. This post was helpful as I’m making these for my 2 year old’s birthday party. I know the little ones won’t be able to handle cracking something so hard open…your post has really helped me!!

    Hi there! Love this idea and plan on doing it for my son’s birthday. If I harden them in the oven are they still soft inside?

    Mine turned out more like mud (or something else the dinos left behind) and didn’t keepisode the form. What did I do wrong? Too much water?
