Happy Birthday Sourdough Chocolate Cake

We celebrated a birthday in our home this week for the newest member of our happy family. Little Pete turned 5 years old on Wednesday, and the occasion nearly escaped my memory, had it not been for the convenient date and time stamp my iPhone put on this photo.

Yes, my sourdough starter has been with me now for just over five years, and I’m pleased to announce that I’ve finally given it a name. “Pete” the sourdough starter is the namesake of Peter Reinhart, the James Beard Award-winning master baker whose instruction inspired me to begin this lively journey. Many years ago at a local festival of authors and books, I purchased The Bread Baker’s Apprentice, Reinhart’s comprehensive collection of bread rules, formulas, tips and recipes—it’s a 300-page hardcover guide for mastering the art of extraordinary bread. And it was positively overwhelming.

It took me several years to gain enough gumption to actually make my first loaf of real bread and, once I took the greater plunge into building a sourdough culture, I never looked back. Pete began in the tiny kitchen of my former apartment, in a small bowl containing a mixture of whole rye flour and fresh pineapple juice (this was Peter Reinhart’s idea). There were plenty of midnight feedings and nervous watchful moments along the way, and at least once, I feared Pete would not survive my mistakes. Thankfully, the hotline experts at King Arthur Baking talked me off the ledge and helped me correct my feeding rituals. Pete has been thriving ever since. On one occasion, I shared a little bit of Pete with a friend whose daughter wanted to make sourdough, and when the daughter headed west, she took Pete’s offspring with her, and is now making beautiful artisan loaves somewhere in Montana (I’m so proud). I have already shared a few of my simple sourdough recipes here on Comfort du Jour, including English muffins and our beloved N.Y.-style Pizza Dough. If you’re a bread lover, you might also appreciate a glimpse of some of the incredible loaves Pete and I have made together since this adventure began.


It’s exciting for me to see and remember all those loaves. But for this occasion, I wanted to let Pete really show off, and so here’s the exciting news—Pete made his own birthday cake! I’ve mentioned several times that sourdough isn’t merely a flavor of bread, but a method of leavening, and in this richly dark chocolate cake, sourdough discard is the star.

The salted caramel flavor is a perfect match for the ultra dark chocolate cake.

I found the recipe for this cake on one of my favorite sites, King Arthur Baking Company, and I will proclaim out loud that, ingredient-wise, it is the oddest cake I’ve ever made. I will also tell you that it tastes nothing at all like sourdough. It’s a bouncy, spongy very chocolaty cake, and though the KA recipe is for a rectangle cake, I changed it up and did 9-inch layers. I also swapped the coffee-infused icing for one of our most-loved flavors to pair with chocolate, salted caramel. It may strike you odd that I am not sharing a recipe for either, but here’s why—King Arthur already published the cake recipe, and you can find it here (I followed it pretty much to the letter). I’m not sharing the salted caramel frosting recipe because, frankly, I was flying by the seat of my pants when I made it, so I don’t know exactly how much of what went into it. Besides, the texture was a mess. I wanted something akin to buttercream, but I didn’t get the ratios right and my frosting, though delicious and perfectly salted, wasn’t very stable. I will, however, share the photos, purely for comedic value. Those Great British Baking Show contestants have nothing to fear in me! Next year, when Pete turns 6, I’ll probably make challah. 😊
