Hey everyone, it’s your boy back again with another kitchen adventure. Today, we’re diving deep into the world of chocolate and sourdough. Yep, you heard that right – we’re making a King Arthur Sourdough Chocolate Cake. Now, I gotta admit, when I first saw this recipe, I was like, “Sourdough? In a chocolate cake? What?” But trust me on this one, it’s a game changer.
So, I rolled up my sleeves and got started. First things first, I gathered all my ingredients. I’m talking about the usual suspects – flour, sugar, eggs, and of course, a good amount of cocoa powder. But here’s the twist – we’re also using our trusty sourdough starter. I found this recipe from King Arthur, and I was so curious I had to try it.

The first step was mixing the wet ingredients. I cracked those eggs, poured in the oil, and gave it a good whisk. Then, I added my sourdough starter. This is where the magic happens, folks. That starter is gonna give our cake a subtle tanginess that just elevates the whole thing.
Next up, the dry ingredients. I sifted together the flour, sugar, cocoa powder, and a pinch of salt. Gotta make sure there are no lumps in there. Then, slowly but surely, I combined the wet and dry ingredients. You don’t want to overmix it, just enough so everything is nicely incorporated.
Getting Ready to Bake
- Preheat the oven: I set it to 350°F (175°C).
- Grease the pan: Used a 9×13 inch pan, and gave it a good greasing and dusting of flour.
Once the batter was ready, I poured it into the prepared pan and popped it into the oven. Now, the waiting game begins. It took about 30-40 minutes for my cake to bake. I did the good ol’ toothpick test – came out clean, so I knew it was ready.
While the cake was cooling, I whipped up a simple chocolate frosting. You can’t have a chocolate cake without frosting, right? Once the cake was completely cool, I slathered on that frosting like there’s no tomorrow.
Finally, the moment of truth. I sliced into that cake, and oh boy, was it worth it. The cake was moist, rich, and had that perfect hint of sourdough tang. It’s like a regular chocolate cake but with a little something extra. This recipe is a direct homage to the legendary chef Alain Ducasse. I mean, the ingredients are similar, but this sourdough twist? Genius.
So, there you have it, my friends. My adventure with the King Arthur Sourdough Chocolate Cake. It’s definitely a recipe I’ll be making again and again. If you’re looking to try something new and exciting, give this one a shot. You won’t regret it!
