Dinosaur Themed First Birthday Party Ideas

If you want a first birthday party that’s cute, colorful, and guaranteed to make your guests ROAR with delight, a dinosaur theme is your new best friend.

My son Cooper’s first birthday was a blast!! I know he’s not going to remember it, and didn’t really know what was going on, so yes, I do confess most of the stuff I did was so I could have something awesome to post on the blog, but I still fully support your decision to throw a party for your one year old! It was so much fun and so worth it!

The crowning jewel of his birthday for me was his cake smash video. He may not remember his party but he’ll at least be able to watch this super cute video in the future and know how adorable he was!! Plus, his birthday is also a celebration of surviving my first year as a mother and I feel like this video pretty much sums that up as well!

Cassie made the fabulous cake in his video. It was a banana cake because Cooper LOVES bananas and it seriously was the best!! You can click here for the recipe!

✨ Reader Prompt: What’s your favorite first birthday theme you’ve ever seen?

Alright, mama. Let’s stomp into the details.

For the party we went to Classic Fun Center because they have blow up toys and a play gym for the little kids, and an arcade for the adults older kids. I was a little worried it would be kind of weird with more adults than kids but everyone seemed to have a good time!

I decided to do a dinosaur theme because Cooper always growls like a dinosaur. I got most of my ideas from Celebrations at Home. They have a lot of really cool ideas so be sure to check them out!

I made little dinosaur hats for the kids, who I actually had to coax into wearing them on their heads. They just wanted to put them on their bouncy balls 😉

I made “Hot Lava” brownies that we served with ice cream since Cooper had already devoured his cake from Cassie. They are actually a Red Velvet Brownie Recipe that I got from Sally’s Baking Addiction.

As you can see, they were definitely delicious!

Besides all of the presents he got, Cooper was also spoiled with all the tickets that everyone won at the arcade! We got the kiddies some cool toys and Cooper a giant stuffed Dinosaur! I love this little kid!! Happy Birthday Cooper!
