Notes
I have experimented with this recipe several ways. 1. I often add a cup of runny sourdough discard to the batter. I haven’t played around with letting it ferment the batter into a sponge, since I bake it right away. But it would be totally possible to make the batter with some sourdough discard and refrigerate it for a day or two to let the discard do it’s magic and ferment the batter. If you go this route, the batter will be somewhat thick. Don’t fret, that’s normal. Bake as directed and if your batter is cold be sure to add a couple of minutes to the baking time.2. I have skipped the cocoa powder and it was still great!3. I have thrown in some leftover cocoa grounds (from my @drinkchoffy) and that was kinda fun too! 4. I have used both whole wheat and white flour. Both turn out nicely!5. I had a reader report back to me that she added one cup of grated zucchini to the muffins. She said it was fantastic and it stretched the recipe out to make a few more muffins!
