This is a 6 inch and 10 inch cake. Buttercream with fondant accents, toy cars. Chocolate number 3. I sent my friends here to cakecentral to get ideas for a Cars cake for their 3 year old son. The husband then picked their favorites and came up with this design. I'm not 100% sure which cakes he used for inspiration to give original credit to so a general thanks to all CCer cars cakes.
