I actually think a good processor makes ok cakes. I don't use it for that now, as I finally, after very many years, got a stand mixer in December.
But it does make ok cakes, especially with SR flour and 10ml baking powder as well per 200g flour. It is a magimix, and even given my new love affair with the kmix, the magimix is the thing I would save from a house fire!
I don't find it too bad to wash up, and also use the bendy spatula. I chuck it in the dishwasher as often as not.
I suppose it isn't worth it for people who don't cook heaps from fresh or who don't have lots of kids. I do have both situations, and work too, so I luffs it, as they say on here!
