I started with a Funfetti style cake because kids always like sprinkles and color. I used my cake leveler to level it off and make it easier to frost. I decided to go with chocolate buttercream frosting, as it is quite delicious (says the person who ate about 2 cups of leftover chocolate frosting during the holidays). In the middle, I did a layer of my homemade wineberry jam (I canned several batches of this jam since the berries grow wild on our land, so I seem to have an almost endless supply of it). After frosting, I did a border of shells around the bottom. I loathe making shells - they are the toughest thing I've learned so far, so I wanted to make sure I got to practice them. You'd think they'd be much easier than they are.
Once I had the cake frosted, I mixed up a batch of vanilla buttercream, and set about mixing the colors I would need: blue, red, yellow, black, gray, and white. I used a coloring book picture of Thomas the Train as my guide for the picture on my cake. I used the stars and dots techniques on the cake. I still need to work on remembering to rotate my stars so the frosting below doesn't show through so much. After I finished the train (which took me quite a while!) I used my #3 tip to write on the cake.
