I've been asked to make a large wicker basket cake. I was thinking of making 11X15 rectangle cakes and stacking it approx. 10 - 11 inches high and will carve slightly to enhance the shape.
I think this will make about 150 servings.
My question is this - what kind of supports do I put in the cake. I know I have to put the cakes on cardboard, probably half way up. Should I use cardboard or foamboard and should I also put dowels in the cake for extra stability.
I was going to pipe the basketweave and then airbrush.
Any tips or advice would be greatly appreciated. I have to deliver this cake - approximately 20 miles so I don't want any of the icing to slip off the cake.

Thanks for reading this!

Nobody out there can help me???

Hmm....that's a lot of cake! OK, here are my thoughts (and I'm NO expert, so take it for what it's worth!!
I would probably do it in 3 sections - doweling between the sections. (are you filling the cake? I am assuming yes...
So I would do 1 11x13 then put another on top, on a piece of foamboard (wrapped in cling wrap) with dowels supporting underneath. Then repeat. I would probably also do a couple of dowels all the way through the whole tower of cakes.
Good luck! Sounds like a big one!

Thanks djs328. I appreciate it.

I agree with djs328. Boards and dowels approximately every 4 inches. I prefer to use 3/16" foamboard rather than cardboard.

If you're filling the layers with something other than buttercream, you may want to stack the layers with a relatively small piece of foamboard (or whatever you're using to separate), carve the cake, then take the layers apart. Dam, fill, stack and dowel as normal. This will prevent your carving through the dam and into the filling.

I also agree with djs328 regarding driving a couple of long, sharpened dowels all the way through the cake and down into the baseboard for extra stability.

This is so helpful. I really appreciate it.
