Hi I am littlebit from the KT. It is easier to use my main e-mail addy when I want to e-mail a Kt member. Here is the recipe for the cake. I went ahead and made a starter by adding the sugar,milk and flour and putting that in a Ziploc bag for a future cake.I didn't have a starter when I made my first one so I just Started on day 10 and didn't pour a starter off. You can also use any flavor pudding to make it different. I have used banana,lemon and chocolate. I leave the cinnamon out when I change it. 
Thanks for posting this for me!
