I'm a really good cook. Honestly I promise., I can make pies, bread, biscuits, pastry etc but cakes manI'm horrible at them. My baking powder is fresh, have tried plain or self raising, I cream the butter and sugar really well, don't over mix once flour is added etc. where am I going wrong?? The only thing I can think of is that I don't have a sieve and I use value flour. But surely that can't be it can it?
