bottomless baking tins - how do they work?

[mousmous]

have been given a few tins by a friend as want to do a minnie mouse cake for dc birthday...
they don't have bottoms

will the dough not just leak through?

Surely they must have loose bottom s

no lose bottoms. surface is smooth, a bit like cookie cutters, just bigger.

How weird
Does it look like they should have loose bottom s which weren't provided

no 'lip' or similar. looks different to the lose bottomed ones I know.
I only have spring tins myself.
maybe have to go and get different sizes then...

Maybe you are supposed to bake a large square cake and use these as a cutter?

Are you sure it's for baking in? Sounds like its to be used for cutting an already baked cake

Yes is the edge sharp?
I have a brilliant minnie mouse cake tin btw happy to send it to you

here:

I would guess you place baking paper on a heavy baking tray then place the shape on top. You could always line the shape but just greasing should work. It shouldn't leak as long as they lay flat together.

I had number 1 like that for dd first birthday, the trick is to put foil underneath and kind of roll it underneath around the tin

It did leak a bit but not massively

Ooh thats a good idea coco
Do let me know about the tin. I don't need it

That's the sort of tin I would use for a cheesecake!
Foil underneath should work but a tray underneath might be a idea too

It sounds like it is what is called a "Cake Frame". No good for liquid batters like Victoria Sponge (or many American recipes) but good for thick fruit cakes and could be OK for Madeira, but not certain.

Alternatively you could make a rectangle cake and then shape a minnie mouse shape out of it post baking

thanks all!
I'm planning to do a carrot cake, so it's quite gloopy and not too liquid.
I guess I will have o do a trial run.
the other dc want's a snake

You want me to send mine? It worked brilliantly with plain sponge

thank you for the kind offer, I think I will try it with the bottomless tins.
