I got adventureous this year and decided to replicate Blue's house from the show. The big cake is just a 9x13. The house is made of a 9" square cake that was quartered. I only used 3 of the quarters though (4 seemed too high). For the roof I made a cake in a loaf pan and then trimmed it to a triangle. Then iced in appropriate color and style after assembling. The tree was made on waxed paper using the wilton candy melts. And the grass was using the grass tip.
