Making a Thomas /Rosie Cake

Make it more simple. Do two cakes as a base for each.

Ice them in green like grass.
Take some brown icing to make a track and then place toy train cars on top of that.

Here's a tutorial I plan on following for my son's cake. It can easily be adapted to Rosie, as well. If you want it bigger, you can use multiple pieces of cake, instead of making it from one piece.

I saw a blogpost a few months back about making creative cakes easily. The woman who did it says she uses figurines for the top of the cake (I'm thinking of doing this because my son wants a Jonah & the whale cake!) You could basically do the same thing with trains, etc...

Here's the post...good luck to you!

I did a TON of research last year because I wanted to make a Rosie cake for my daughter's 2nd birthday. We did a semi-elaborate 3D train cake with this cake pan (but didn't follow their directions for frosting- we made purple frosting.) http://www.wilton.com/shapedpan/Choo-Choo-Train-Pan

That cake didn't seem like it would go very far, so we also made a standard rectangular cake and laid the take-n-play tracks on top of the cake with Rosie on the tracks. (We have James' train wash and the tracks for that made a small circle that fit perfectly on our cake. I think my MIL lent us a baking pan that was a little bigger than 9x13.) It was so simple and so cute- the take n play tracks and trains were perfect!

Feel free to message me if you're interested in hearing more. Good luck!

You could try doing a frozen buttercream transfer. It's easier than it sounds. You take a coloring book page, trace it, decorate, freeze, and then place it on the cake. Go to youtube and find it. There are some great tutorials. Good luck!

If you goto Betty crocker.com they have all sorts of ideas. Type in "train cake" in subject and one will come up.=) good luck!
