Hi Wilted. omamcm is correct about the angle food cakes. You do not grease or flour so they will climb the side of the pan during baking, but will also stick. You must loosen with a knife blade. If the pan is dark, that is why it may have burned due to the heat absorption. You may need to reduce your heat by 25 degrees and also reduce the cooking time to cook in a dark pan without burning. Good luck.
