It’s not every year you get to eat a robot truck for your birthday.

But for one little boy, that’s exactly what happened when he asked his parents for a Transformers cake for his sixth birthday party.

When it came time to blow out the candles, he and his friends watched as the truck-shaped cake turned into a covered-with-frosting version of Optimus Prime.

The cake’s creator even shot footage of the testing process for the animated platform – minus the cake – before the big day.
