Coolest Optimus Prime Truck Birthday Cake

I made this Homemade Optimus Prime Truck Birthday Cake for my son’s 4th birthday. He loves Transformers. I thought about just ordering a cake topper, but where’s the fun in that!? So I ended up making this cake.

First I baked a 1/2 sheet cake and a 1/4 sheet cake, just trying to have enough cake to work with. I ended up throwing a lot of it away, as I only needed certain parts. Then I cut the bottom layer rectangular to be the base of the cake and then the next layer was just the front of the truck, then I cut a few more pieces to form the upper layers of the truck as best I could using trial and error, and a toy of the truck as my guide.

Next I iced with home made buttercream icing. I accidentally grabbed the Delphium blue Wilton coloring at the store instead of the regular blue, so the blue coloring was a little off. I used store bought sparkly gel icing for the flames and also writing his name on the truck.

The wheels are donuts, the grill is just aluminum foil that I drew lines on and stuck to the icing. The smoke pipes are markers covered with foil, and the other silver parts are Hershey’s chocolate candies stuck on with icing. The yellow lights are nerds, and the lights are rings that I found in the party section at Walmart.

Everyone loved the cake! It took me about 4 hours, but that includes baking time. It actually wasn’t that hard, I am just not a very experienced baker. It was so worth it to see my son’s expression the when he saw the cake the next day!

  1. Tree, you did great! That truck looks so cool and real. Girl, you have talent – can you imagine what you can do with a little more practice. Thanks for sharing and keep up the great work. I know Damien was proud of that cake.

  2. I too am a make it yourself mom but was a little intimidated to try Optimus Prime. Now that I have looked at your cake and read your comments I think that I will try this for my 6 year old. I just hope that it turns out half as good as yours did. Great job!

  3. cool cake!! what a great creation. my son wants a transformers cake for his 4th birthday,was just going to buy one until i saw yours, im so hoping mine turns out as good as yours.

  4. How big was the base of the truck? Was it the size of 1/4 sheet cake? I’m thinking of trying this for my sons 8th birthday in July.
