Cindy, your best bet is to try the recipe as written, though you could start checking earlier to see if it's done. Since it's black on the inside rather than outside, it might be it works like a lighter-colored pan. If it does bake more quickly, you'll know to lower either temperature or time next time out. Personally, I don't like those spray oil/flour combinations; I prefer to leave the flour out, but if you like it and it works for you — go for it! PJH
