has anyone got a birthday cake suggestion for a three year old?

[oranges]

he loves trains, cars, teddy bears, usual stuff and hasa mother who can't bake. I also have one round cake tin. May be able to get a sandwich tin or fairy cake cups, but nothing else really. any ideas? could i make a mountain cake out of cupcakes and put a bear on it (he keeps singin the bear went over the mountain. ) but how would i do a bear???

Best idea is simple chocolate/victoria sponge cake then get some characters that he likes and put them on the cake eg Thomas the Tank engine on chocolate finger train track or oy cars on a road made of smarties ('glue' the cars on with icing) He'll be thrilled with the 'toy' part of the cake and it should look effective too.

do you mean non edible thomas toys? you know, i never thought of that!

do a spider web. ds1 had it for his 4th birthday and it went down well.
just make a round cake (ours was choc), ice it and then use a diff colour icing to make the web.
you just do the icing in circles on the top and then drag a cocktail stick through them from the centre to the edge iyswim:?
make spiders from marshmallows and licquorice shoelaces

I did a 'train' cake as described by K&P'sLoveChild. Just iced some train tracks on a round cake and stuck a couple of trains from DS's IKEA trainset. This was for his 2nd birthday and he was made up with it. This year I plan to pull off a similar trick with some plastic dinosaurs...

the train tracks are a really lovely idea, and i think even i could manage that! thank you! I was having nightmares of moulded cake pans and three dimensional cakes.
