inch tall cake.
Hpw do I do this without baking 2 cakes and leveling?
Add height to your pan by making a collar with foil or parchment paper. Put it around the inside of the pan and spray/prepare the pan as you normally do. I do this for most cakes I make.
I can't tell you how much batter you need to make a 3-inch cake, however.
Thanks so much, I'll have time tomorrow evening to play with batter.
there is an article on how to collar your pan, and i used wax paper, hope this help, if you can't find it another good tip is to use the cake batter like a glue along the sides of the pan
here is an article on CC to collar your pan:
I'll be doing a collar on a 11x15 also this week for the same reason as you. I've never collared anything other than a round so I plan on trying to make a small crease where the corners will to try to hold it in place better while pouring in the batter.
