    If you love easy snacks and kids recipes, I have a treat for you! These Dinosaur Egg Rice Krispie Treats did not last long at my house. They are fun to make with kids and you can combine this activity with our fun Dinosaur Toss game for a day of dinosaurs!

    This past week I have been participating in Play, Craft and Learn with Dinosaurs, a series with some other kid bloggers where we have been sharing ideas for fun with dinosaurs. We have shared dinosaur themed posts in the following areas - learning, fine motor, gross motor, arts and crafts and today is food.

    You will also enjoy our Rice Krispie Treat Pops and our Honey Nut Cheerios Treats.

    Dinosaur Egg Rice Krispie Treats - These are a fun addition to a dinosaur study or for any day.

    Ingredients:

    • 3 tablespoons of butter
    • 5 cups of mini marshmallows
    • 6 cups of Rice Krispies
    • 6 Oreo cookies
    • Egg shaped mold (optional)
    Ingredients for rice krispie treats

    My daughter and I did some research about what dinosaur eggs really looked like. No one can know for sure, so I thought we had a little creative license. When I think of dinosaur eggs, for some reason I imagine a speckled egg so we went with that. To create a speckled look, just add some crushed Oreos to your Rice Krispie Treat mixture.

    Before you start, crush 6 Oreos in a zip top bag. I gave my daughter a mallet and let her crush the cookies. You don't need to crush them into a fine powder as the larger chunks of cookie will create a nice texture to the treat.

    Melt the butter in the microwave in a large bowl. Remove from microwave and stir in 5 cups of marshmallows.

    Return bowl to microwave and heat for 45 seconds. Stir and heat for another 45 seconds or until the marshmallow mixture is smooth.

    Pour over 6 cups of Rice Krispies. You can also just pour the cereal into the marshmallow mixture if you used a big enough bowl. I did not.

    Add in your 6 crushed Oreos and stir together until well combined.

    If you have an egg mold, grease it with cooking spray, and scoop the Rice Krispie mixture into it to make an egg shape and then slide out to cool. If you don't have an egg mold, you can just form an egg with your hands.

    These make a great addition to a dinosaur study, like our Preschool Dinosaur Crafts. The Oreos add chocolate flavor in addition to making them look more like I'd imagine a dinosaur egg might have appeared. For another fun snack try our Rice Krispie Pumpkins Recipe.

    FAQs For Dinosaur Egg Rice Krispie Treats

    Can I make these treats ahead of time?

    Yes! You can make them a day ahead and store them in an airtight container until you're ready to serve.

    Do I need to grease my hands to shape the eggs?

    It definitely helps! Lightly greasing your hands with butter or spray will make shaping the sticky mixture much easier.

      These look great, looking forward to making these for a dinosaur-themed activity day with my kids. For preparation and shopping purposes - approximately how many of those eggs did those amount of ingredients make?

        I got the mold at a yard sale. It seems to be an easter egg mold. It is about 4-5 inches big. You can check Amazon.
