Many times a cake recipe will tell you to use 2 round pans. I eliminate using 2 and use only 1 deep pan. Then when the cake is cool enough to handle I take a piece of sewing thread about 16" long and wrap it a finger on each hand. Then slowly start pulling it through the middle of the cake. Continue until the thread cuts through the cake completely. And now you have 2 cake rounds. Happy dividing!
