I love baking. But we have a new cooker and every cake I've made has a burnt bottom. The latest is completely inedible. Not just singed. Properly carbonised. I'm not sure if it's the oven, which has a burner down the middle at the bottom (rather than the back), but can't think what else it might be. Slow cooking meat is fine, and bread is a bit dodgy but ok. Cakes, a disaster. Any ideas? Thanks.
