Cake problem

[1Wanda1]

I am making a shaped cake today for a child's birthday party tomorrow. Have planned the cake and bought all supplies except for the cake board. I assumed I'd be able to get a large rectangular cake board from my local Lakeland. They don't have rectangular ones. Nor does Hobbycraft. Our local cake decorating supplies shop has closed. It is now too late to order anything online as the party is tomorrow.

I need to decorate the board with icing as part of the cake design. Any ideas of what to use as a substitute board?

A glass chopping board 😉

Cardboard covered in foil? Can you ask neighbours for help? Buy something on amazon for delivery today?

Most supermarkets sell them now?

Amazon doesn't do same day delivery to my town. Had thought about some kind of chopping board covered in foil but am worried the icing won't stick or the foil will move and crack it.

Supermarkets only have round ones

As long as you whack buttercream under the fondant, it'll stick. Sturdy card covered in foil is only what the commercial cake boards are but more fancy...

Cover a tray in foil?

Or a chopping board

Would it stick to clingfilm?

You could cover a chopping board in birthday wrapping paper or something then wrap it with clingfilm. If you make sure the wrapping is neat and pull the clingfilm tight (do a few layers) that might work but you would have to be careful not to cut the clingfilm when you cut the cake.

Or just use a nice coloured chopping board if you can buy one, tk max usually has stuff like that in.

I've found a baking sheet (aluminium) that's the right size. Just wondering whether icing will stick to it? If I put buttercream under fondant, wouldn't it just slide off anyway? Not sure.

The buttercream will stick it. Or make up a small amount of icing sugar and water (thick) and use that as 'glue'

@cantfindname thank you - I will try that. Wish me luck!

A piece of mdf cut to size, smear trex all over it and icing will stick to it. As an ex cake baker this is what I used to do (and what other bakers I know do) for funny shaped cakes.
