I was thinking of making this sourdough chocolate cake for Dad’s birthday, but my cousin has developed an allergy to dairy, and this is full of dairy. However, we’re out of pie, so here’s my opportunity. “Fed” sourdough starter means you feed the starter 8 hours or so before you get started on the cake, and you start the cake about 3 hours before you’re ready to bake, so this requires some planning. The recipe calls for 8½ ounces of sourdough starter, so you need to feed it plenty; I fed mine 4 ounces each of flour and water.
I couldn’t find the camera when I was starting to work on the cake, but the Baking Banter blog entry for this has great photos (and much better than mine would be).
I didn’t use the mocha frosting, I used cream cheese frosting, which was quick and easy and tasty. Actually, the whole thing is tasty. The cake is very rich and moist but not heavy.
