Race car (macqueen) cake

It's been a long time in the cake journey for its more than one year now I baked & decorated a cake. This was Sriram's fifth birthday and all that he wanted was a lightning McQueen which is a one year old request. With two kids its pretty tough to do all that i wish to complete in a day. It took a lot of determination for me to venture in to this cake, but was a big hit in the school and among all the kids. when i placed the cake on the small center table all i could hear was a big "oh" a cake ... first, then a car cake....  celebrating birthday at school is the first time and different experience for him. He was very upset the previous day that we did not call our friends for a party, but I promised him to make his day more fun and special at school which he didn't realise until experienced.

As usual a chocolate cake with white frosting for the stage to place the lightning McQueen.
the white frosting is a pure butter cream frosting. the recipes for chocolate cake and butter cream frosting has been published earlier.
