I made a two layer vanilla cake and some homemade buttercream icing. I tinted most of the icing green and iced the whole cake with it. I then traced a 2 into the icing with a toothpick and piped green grass all around it and down the sides of the cake.
Once my grass was finished I filled in the 2 with brown sugar that I patted down gently and then I used pieces of black string licorice to make it into a train track.
I tinted my remaining icing blue and used it to pipe a waterfall down one side of the cake. I decorated the edge of it with chocolate rocks.
The final touch was to dip the tip of a sugar cone in white chocolate and let it drip down a bit to make a snow capped mountain.
If you're wondering where Thomas is, we just used a toy version that the birthday boy already owned so it wasn't on the cake when I took pictures at home. Just imagine him sitting there on the track ;)
I was really pleased with the final product and everyone at the birthday party seemed to really like it too!
