DS's 2nd birthday is coming up (can't quite believe we made it to here) and i wanted to make a 2 shaped cake with a licorice strap railway track on it with a thomas sitting on the track.

so i have NO idea how to make the shape of the 2. can you buy tins in that shape or should i just bake a slab and a ring shaped cake and then cut it into the template?

also, any ideas for decorations would be greatly appreciated.

TIA
