While I disagree with Spaw about muffins I can't agree with MtheGM about cupcakes ... an American muffin is often packed full of raising agents like baking powder, hence the overgrown appearance, whereas a cupcake has a flat top and interesting icing and is more of a sponge mix. Biscuits are not scones and I personally wouldn't dream of putting gravy or sausages with a scone while cookies are a variety of biscuit. But we all know that, don't we?
