How to Make Sourdough Chocolate Cake with Peanut Butter in Bulk for Your Micro Bakery that Customers LOVE!
If you’re running a micro bakery — or dreaming of starting one — you know how valuable it is to have recipes that are not only delicious but designed for bulk baking. That’s exactly why we created our Long-Fermented Sourdough Chocolate Cake Recipe PDF. This isn’t just a cake recipe — it’s a fully-tested, bakery-ready formula made to help you deliver consistently amazing results, whether you’re baking 6 cakes or 60.
What sets this chocolate cake apart is its long fermentation process. Unlike traditional cakes that rely on instant rise, this recipe uses sourdough to slowly ferment the batter. This approach makes the cake more digestible and more flavorful, and brings a deep, rich texture and taste that your customers will remember. It’s a great way to stand out in a world full of overly sweet, one-note chocolate cakes.
Inside the PDF, you’ll find every detail you need to confidently produce this cake in bulk quantities. We’ve scaled the recipe to work perfectly in either mini loaf pans (makes around 6 dozen!) or 15 full 8×8 pans, depending on your setup. This makes it ideal for microbakeries, farmers markets, cottage food sales, and local events. You’ll save time, reduce waste, and increase your output — all while maintaining high-quality standards.
Tested and Curated FOR MICROBAKERS!
We didn’t just throw this recipe together — it’s been refined and tested over and over in our own bakery. That means you get a recipe that’s already been proven to work in real-world baking environments. We’ve included fermentation timing, ingredient tips, prep strategies, and even batch management advice — so whether you’re baking the night before or planning for a busy weekend, you’ll be ready.
This Peanut Butter Icing - TRULY the icing on the cake
And let’s not forget the peanut butter icing. This is the show-stopping finish that turns your sourdough chocolate cake into a total best-seller. Inside the PDF, you’ll find detailed, step-by-step instructions for making this rich, creamy, slightly salty frosting that pairs perfectly with the deep chocolate base. We’ve even included tips on how to frost mini cakes for presentation that wows.
Customers love this cake because it feels indulgent but intentional — the long fermentation process gives it a handcrafted touch, and the flavor keeps them coming back. If you’re offering gut-friendly, naturally-leavened baked goods, this cake will align beautifully with your brand values and resonate with your health-conscious (and dessert-loving!) customers.
The best part? You don’t have to figure any of this out yourself. When you purchase the PDF, you get an instant download sent to your email with every single step laid out clearly — from mixing and fermenting, to baking and frosting. Whether you’re new to sourdough cakes or have been experimenting for a while, this guide takes out the guesswork.
