King Arthur's Original Cake Pan Cake

This is a great basic chocolate cake. Comes together quickly, bakes up moist without being too fudge-y. The frosting is pretty rich but compliments the cake nicely. This recipe is very straight forward both in instruction/technique and in flavor. I jazzed this up a bit by replacing some of the flour and water with 5 ounces unfed sourdough starter. I couldn't detect a sour flavor but it did add another (subtle) layer of flavor. I have also made this using 70% whole wheat flour and 30 % cake flour. I made this in an 8 x 8 cake pan, halved the icing (it was plenty) and baked 30 minutes. Lastly this cake is vegan!
