If nothing has convinced you that you need a sourdough starter in your life yet, this will. At least it convinces me that I can’t do without one!
This started as a recipe from King Arthur Baking and after I made some tweaks it is the favorite chocolate cake recipe in our house.
When I was a teenager working in a historical tea house I learned the trick of adding coffee to chocolate recipes. Since we don’t drink coffee I keep Pero (a coffee substitute) on hand for the trick but if you don’t have coffee or Pero it will still be one amazing chocolate cake!
This cake freezes very well too and keeps tender and fluffy and stays fresh much longer because of the sourdough.
