This 3-Rex Birthday Party is a Roaring Good Time

Forget about T-Rex, 3-Rex is taking over the internet! Three year olds love themselves some dinosaurs, and moms are jumping on board with this pun-filled party theme. So when Charlie’s third birthday was coming up, I decided it was time to party like it’s 83 million BC!

While I love the theme, I don’t love the traditional dinosaur party colors of greens and browns—so I decided to make our 3-Rex party bright and playful, just like my little guy. I started with the Printable 3-Rex Backdrop, lots of balloons, and even got crazy with some spray paint on letter balloons. Charlie loved watching it all come together for “my party!”

The star of the show ended up being this adorable cake from Confection Deception. She custom created this little guy to match our invitation and printable decorations and I’m in love! The frosting scales, those tiny T-Rex arms, that tail! The cuteness doesn’t stop.

She captured my illustration perfectly right down to his little party hat!

What little boy party would be complete without something slightly funny and icky at the same time! These chocolate donut holes became “Dino droppings” and were a hit with the kids.

Assorted M&Ms on clearance after Halloween matched our color scheme perfectly while yogurt pretzels became “Dinosaur Bones”—another kid favorite.

Store bought cupcakes quickly became “Stegosaurus Cakes” with the help of our party printables and candy corn!

Homemade dinosaur cookies were a breeze with a T-Rex cookie cutter, green icing and sprinkles!

I set the kids table with these perfect bright dinosaur plates from Day Dream Society. I love that they offered them in a fun color palette instead of traditional dinosaur colors.

Each little guest had a Printable Dinosaur Party Hat waiting for them at their place setting.

Little guests were each sent home with a favor bag full of treats, including Dinosaur Suckers, toy dinosaurs, dinosaur egg (easter egg filled with candies), and some play-doh to make dino prints with.

For our final favor, I couldn’t resist having a little fun with these twist pops with a spin off of our popular Unicorn Party Favors. Instead of a Unicorn with a candy horn we have a Printable Triceratops with candy horn!

    I was wondering which tip you used to make the scales on the dinosaur cake and also if those are just round cakes?
