Gluten free choc cake

[dcb]

Can I just substitute usual flour for rice flour?

And is baking powder gluten free - it doesn't mention it on the packaging?

Thanks

I would use a gluten free blend rather than just rice flour or the texture can be odd.
Some baking powders are not but most are.

thanks x

Nigella has a flourless brownie recipe that uses ground almonds and is fantastic, but my friend has the recipe!
