Anyone ever done this, and if so, how do I alter the baking powder from the 9x2 inch recipe to a 6x2 inch?. Some of you are SO good at that math, I just…well, am apparently terrible at it! I have this problem every time I bake! hehe Any help would be greatly appreciated!
ETA I will make the entire recipe and just make multiple 6 inch layers. Two or three, whichever will work.
