I have never made this myself, but I have literally been looking for this recipe for YEARS!!! My grandmother used to make Herman cake when I was a little kid, and I used to have such fun helping her to "feed Herman" and "stir Herman". Unfortunately, after she passed away in 1989, my grandfather got rid of a lot of stuff that he thought was junk, and her handwritten recipe for "Sourdough Herman" (as she called it) was one casualty of his housecleaning. Thank you for posting!
This was always in my recipe file as Herman the German Coffeecake. When I share the starter with friends, I always include information on the care and feeding of Herman. It makes the best coffeecake ever! At one time I had a recipe using the starter in chocolate cookies. If anyone has the cookie recipe, please post it.
Been looking for this!!!!!
