Is baking powder the same thing as bicarbonate of soda?

[ChocolateCoins]

And if not can I use BofC instead of baking powder? Will it make much difference?

it's not. Have a lookee here

Not the same thing. Bicarb is gentler as a raising agent I think. Bicarbonate of soda is sometimes referred to as baking soda. Best to go and buy some baking powder if you're baking cakes.

I think Bicarb with cream of tartare makes baking powder?

Thanks for the replies. I think I got confused with baking soda/powder. No muffins for us today then.
