Hi everyone. I am looking for a cake with yeast in the batter. Years & years ago, in my younger days, a Russian friend of mine got me a birthday cake. She said it was from a Russian bakery. 2 layer frosted cake. Don't remember the taste, but it was tall and the texture was very coarse. Reminded me of a carrot cake. She said it was made with yeast. I've never run across yeast in cake batter. Anyone have any ideas?
