Coolest Thomas the Train Island of Sodor Birthday Cake

First of all – thanks to Christina R.! Her cake really inspired me and my cake is a copy cat cake of her Thomas the Train Island of Sodor Birthday Cake! I am new to cake decorating and her post helped me a lot!

For my mountain – I just baked a 13 X 9 cake that I cut, stacked and carved using butter cream frosting for the ‘glue’. I didn’t have any dowel rods so my cake does not have any additional support but it did not seem to need it. My mom didn’t think it looked at all like a mountain until she saw the finished cake. After assembling the mountain I crumb coated the entire cake.

I first frosted all the green grass areas – then the blue water. I let the cake set in order to form a crust – I think that is the right word – before coming back and adding the details. The stones on the tunnel and bridge are just mini marshmallows cut in half and coated in gray frosting. I used a flat tip to pipe on some ‘mortar’ and then added the stones. The bridge is a rice crispie treat – just the store bought kind – cut with a sharp knife to shape. I placed the bridge, frosted it and put the stones in place. Some of the left over marshmallows I cut up even more to use for the small rocks at the bottom of the water fall.

I used some of the left over cake from the 9 X 13 cake and crumbled it up, mixed in a little sugar and brown sugar to make the dirt under the railroad tracks. My trees were store bought then cut to size.

I realized that there was no room to write ‘Happy Birthday’ so that is when I came up with the idea of adding another foam board under my existing cake board. My boyfriend cut the foam board to give that ocean wave look. I put some frosting on the foam board before placing the cake board on top of it – just so that it would not move once it was in place. Then I made another recipe of butter cream frosting – colored it blue and created the ocean!

It was lots of fun to make – I have to admit it took longer than I thought. I probably spent a total of about 8 hours just assembling and decorating it. It was worth every minute! My grandson loved it. He and his friend dived right into the ocean – licking the icing off their fingers. Then they drove Thomas all over the tracks – at first I didn’t want him to ‘mess up’ the cake but then decided it was his cake and he was loving playing with it and eating it!

Thanks again for the inspiration Christina!

  1. This is so cute! My son is a Thomas the Train nut. I was planning on making him a cake very similar to this one for his fourth birthday in December.
