My son was about to turn 3 and I had a week decide what cake to make. He loves race cars – specifically Lighting McQueen from Disney Cars. But I knew better than to attempt making a car shaped cake – especially considering this would be my first time decorating a cake. A plain ol’ round or square cake sounded too boring for a kids party and buying a number or car shaped pan seemed like a waste.
Well why not cut out a ‘3’ shaped cake. Nah – too much crumbs which could make decorating difficult. And then it struck me! How about making a 3 shaped cake pan. No, I do not do metal work – but stay with me. Take 2 round cake pans and place empty can in each and pour the batter around them. 
So you have two loops and join them to make a 3.
Have a look at the pictures, it will make a lot more sense. Note, I placed potatoes in the cans to weigh them down and have baked potatoes too.
I put a layer of buttercream all over the cake. I then used cookie crumbs over the cake to make it look like a road. My older son then decorate the sides and top with candies. Yes when your kids help it will be a wee bit messy but it was having a perfect cake or having a pretty good cake with a happy son.
