Train Cake This cake was amazing. I made it for my son's 4th birthday; he wanted a Toy Story birthday party. So I made this cake, and put some of his action figures in it. I used two boxes of the funfetti cake mix, which left enough mix over for 6 cupcakes. I froze the cake for almost 4 hours before I cut into it of frosted it. I did the crumb coat after my kids had gone to bed, and then stuck the cake back in the fridge until the afternoon of the next day. I used a chocolate whip cream frosting, which is really hard to add food coloring too, but worked really well because it doesn't stick or pull at the cake so you end up with less crumbs in the frosting, but I still recommend a crumb coat. I put black liqurious bits int the front back of the engine, and a miniature toy Woody in the divet to look like he was driving. The next car had mini M&M's in it, the next car had his #4 birthday candle, and salt water taffy, the third car I put some fruit snacks in, and the last car I put a miniature toy alien from Toy Story, and more salt water taffy. Instead of peach O's I used gummy Life Saver's for the wheels, and instead of making the train track out of frosting I bought chocolate Twizlers, and cut them into pieces about 2 1/2 inches long, then I took more chocolate twizlers and cut them in half lenghtwise, and laid them over the 2 1/2 inch strips for the railroad ties and bars. It looke amazing I set it up on display for the party, and people didn't even know it was the cake. Everyone was amazed that I made it, and how nice it looked. My son was so excited about it. I couldn't believe how easy it was to make and frost. I did do a dry run about two weeks before the party that I didn't finish with all the extra candy pieces, just to see if one I could do it, and two how difficult it would be to make. I'm not an expert baker, or cake decorator, although I am very creative, so maybe that helped a little. Truely a fantastic idea.
