I've found the recipe several places online, NYT version calls for baking in 2 8" springform pans (I only have one) Orangette blog uses one 9" springform pan. I have one 8" and one 9". Should this be one layer or two?
It isn't meant to be layered. You could make it in either an 8" or 9". The height will be the difference but the baking time won;t change much. Check them 5 minutes earlier than the final baking time
It's best when done in a single cake in a 9-inch springform pan (or cake pan with a removable base, which is what I use).
That's what I'll do, thanks.
