What can I use instead of baking powder?

[TinyTimLivesinVictorianSqualor]

DD has just told me that she needs a cake baking for taking into school tomorrow.
I said I'll make her the world famous lemon drizzle, but I just realsied I don't have any baking powder and I refuse to go out, can I substitute it??

bicarbinate of soda? bself rasing flour

Baking powder and bicarb are not interchangable.

what is in baking powder i thought it was cream fo tartar and bicarb?

I have no idea

Baking powder can be made from 2 parts cream or tartar to one part Bicarb of soda

1 part bicarb soda and 2 parts cream of tarter. Although if you've not got CofT you're stuffed I think!

Cream of tartar

Looks like I'm as stuffed as a christmas turkey then.

Has the school only just told her today? Seems a bit off to give such short notice. Can you buy one on the way to school?

Can you borrow from a neighbour?

Or nip out, buy a cake and pop it in a tin?

Chocolate rice krispie cakes anyone?

Ha, no, she boguht home her PE bag, with one of those letters in, you know the 'important' ones, that are supposed to go straight home but then take a week?
I'll just make something else.
