His favorite Monster truck is Grave Digger....the graphics on this particular truck are very detailed.
I used this picture as a guide for my cake.
First I made my pound cake in the biggest rectangular pan I have....12X19 I think.
Then I divided the rectangle into three 12X6 inch pieces and stacked them with some buttercream icing in between.
I think it looks like Tow Mater here but....wrong truck :)
The wheels were made of rice krispy treat, covered in buttercream and then in fondant.....attached to the cake with a toothpick.
I painted the designs on the cake using different colored Pearl Dust (mixed with a little bit of Vodka...the alcohol evaporates so its safe for the kiddos).
I added the Happy Birthday message with buttercream icing and Voila! I made a monster truck cake.
I would have liked to had more detail to show the door/hood lines but I am pretty happy with my first attempt at a truck cake.
Thanks for looking!
