3d Dinosaur Birthday Cake

Two nine-inch round cakes, frosting, decorations, and an unquenchable thirst for adventure are all you need.

Step 1: The Raw Materials

Picture of The Raw Materials
  • Two nine-inch round cakes. Cakes made from scratch will be denser and stronger than a cake mix, but you love the Duncan Hines don't you -- just be forewarned that the time you save using a mix will be spent cursing during the frosting crumb coat.
  • Two batches of frosting. We did a butter cream with 50/50 butter/vegetable shortening. Die one batch green. Keep 1/2 of the second batch white and die 1/2 blue.
  • Rolled fondant. We don't know what this stuff is, but we were darn sure we weren't going to make it. Found some multi-colored fondant at Michael's, a big box craft store. Buy the non-stick mini rolling pin while you are at it.
  • Decorations: cinnamon red hot candies for the eyes, candy corn for the tail spikes, chocolate chips for toenails, and toasted coconut for the prehistoric grass.
  • One cardboard cake board, half-sheet size.
  • Frosting pipe tips and bags. Use a star tip. Yes, this makes a difference, so don't skimp here. Really.
  • A partner. Not required, but could speed things up during frosting or at least help pass the time.

Step 2: The Body

Picture of The Body
  • Bake the cakes and cool completely.
  • Take out of pan, and find the center of one cake.
  • Cut the cake in half with a bread knife.
  • Put the two halves together with cuts edges aligned, and place on a work surface as pictured.

Thank you!

Can anyone offer advice on the neck/head?? The head on my "practice" cake crumbled (I made a white cake that was near pound cake density from scratch). What is the extra head piece in the template used for? Also how far in advance should I make the fondant spikes? I want them to be hard enough to use. My son's first birthday party is next weekend!! Thanks!

Frost the joints of the head pieces to make them sticky, insert a few toothpicks into the top of the neck, and place the head on top. The fondant spikes can made and left out in the air the day before to make them firm. If you live in a hot or humid climate, you may want to dry the fondant on a sheet pan in the oven at a low temp. like 125-150F.

Thank you very much!!! I made this by the seat of my pants yesterday and my now 3-year-old is over the moon with it. I am in the good books big time. Highly recommended. I am a novice baker and it turned out really well at short notice. Highly recommended!

If you still have a copy of the template I would like a copy. Also, if you made the cake did you have any problems with the head staying attached? Thanks

Some have mentioned a broken or droopy head, but I think it depends on the cake you use. We reinforced the head just to be sure it would not come apart during transport. To reinforce the head, try sticking 2-3 toothpicks from the top of the head down into the neck, then carefully remove the toothpicks as you serve the cake.

Thanks for the great template and instructions. My 4 year old and her friends loved the cake! I used a box cake and, while I had no problem crumb coating (I froze it before this step), my head broke off under the weight of the frosting. I improvised with a more flat rice crispy head. It took alot more frosting to cover the cake than I thought it would so I ended up with a third accent color. The tail spikes were some pink grapefruit candy from the bulk bin at the grocery store. We carved a watermelon to look like a T-Rex, made some T-Rex bones from a dino sand mold and had a dino dig. Was a great party and the kids sure seemed to enjoy it... especially the cake :)

Ok trying this for my two girls joint birthday party..and holy crap are they going to flip! Just one question... On the square bits that will be cut out (front leg shoulder and two feet) how do I cut them into the shoulder and feet? I see I cut out a square but what do I do after that? Thank You!


I will upload pix when done, I am trying the "First Attempt" cake today to get the feel of it before I do the one for the party.
