This cake was much simpler, but stuck to the same Thomas the Tank Engine theme. I used the same Bin Inn packet mixes for two 20cm round cakes. I cut the top off one of them and stacked the second cake on top with green buttercream in between, followed by green buttercream all over.
To get the Thomas theme in I raided the kids toys and found a diecast Thomas train. For this I made tracks using licorice for both the rails and the sleepers. Most tracks have shingle and rocks around them, presumably for drainage and keeping weeds down or something. I made mine using white chocolate chips and dark chocolate chips. Dropping them straight on didn't have the effect I was going for, so I put them in the food processor and whizzed them. This powdered them a bit, and all the rocks became coated in dust as well as being reduced in size. The chocolate rocks and shingle made a great backdrop to the track. For the remainder of the grassy hill I covered with 'grass' using up the rest of the green buttercream. For this I used a multi opening tip like this one.
It took a flick of the wrist and a quick pull away to get little fronds rather than long strings.
The train went on top and the cake was done. It was all gone by the time we picked Widget and Sprog up from preschool.
