I have a Christmas tree pan to bake cakes in. I am not sure how to use it. It is about 14" by 8" at it's widest, a tree shape. I was going to fill it with water up to about 1/4“ (do you think that is the correct height to measure from? ) from the top and then measure the amount of water in it to determine how much batter I will need to make a cake...but at that point I get lost. I guess I can do the same with my 9x13 and then compare volumes. Can I use any cake recipe in this pan? The metal seems to be a little bit thinner than my other cake pans - should I change the temperature of the oven? etc I do hope that to be able to flip it and then frost it. I will probably be cranking out 20 or so of these. Any suggestions are welcome - even if it is not something I mentioned.
