The fire truck cupcakes were such a big hit, I thought I'd do a fire truck cake! Actually, was contacted by a friend of a friend to make a fire truck cake for her son Nicholas, who was turning 2. Nicholas has some food allergies - eggs, milk, nuts and even soy are no-nos, but butter, fortunately, was not.
Nicholas' mom gave me recipe she used to make muffins but had never tried as a cake. I modified it a bit (using butter instead of oil, upping the liquids) and it turned out pretty great (at least from the little crumbs that I was able to taste while putting it together).
All the decorations are made from gumpaste. I'm not a big fan of the alphabet cutters from Wilton, and have been using ones from Fox Run instead. These, called Tappits, are going to be my next purchase, I think, but I hear they're a little trickier to use than regular cutters.
The fire truck shape came from a Google search of fire truck coloring pages. I found one I liked the best, shrunk it on my copier and traced it on to a piece of gumpaste. Much better looking than freehand, especially when it's my hand doing the freehanding!
