Our kitchen has been buzzing with sourdough creations lately, and we’re absolutely loving it! You might have already caught a glimpse of our delectable sourdough chocolate chip cookies or the rustic scones – pure bliss! Now, we’re thrilled to introduce you to another delightful treat: these wholesome sourdough chocolate chip muffins.
Developing this particular recipe was a bit more challenging, especially perfecting the long fermentation process with eggs involved. Many recipes might skip the fermentation for convenience, but doing so means missing out on the incredible health benefits that make sourdough truly special. More importantly, for our family, long fermentation is key to ensuring these muffins are easily digestible and enjoyable.
Initially, I viewed the long fermentation as an extra step, almost a chore. However, I’ve come to realize its immense convenience. The process simply involves mixing a few ingredients the night before and allowing the dough to rest for 12 to 24 hours. This hands-off approach eliminates the need for an hour-long mixing and baking session all at once. While these muffins can certainly be mixed and baked immediately for a quick treat (I’ve tested it!), embracing the overnight fermentation offers superior health advantages without adding complexity to your busy day.
Once you embrace the world of sourdough, you’ll discover it’s a game-changer. These muffins are not only incredibly delicious and healthy, but they also boast fermented grains and are naturally sweetened with honey. Expect these delightful chocolate chip sourdough muffins to become a regular feature in your weekly rotation, serving as a perfect snack, a wholesome breakfast, or a satisfying dessert.
Recipe Highlights:
These sourdough chocolate chip muffins stand out for several compelling reasons:
- Fluffy, Moist, and Delicious Muffins: Each bite offers a harmonious blend of tender crumb, rich moisture, and irresistible flavor. Made with simple, wholesome ingredients, these muffins are a treat you can feel good about. The natural sweetness from honey pairs beautifully with the tangy notes of sourdough and the comforting melt of chocolate chips, creating a truly yummy experience.
- Super Easy to Make: The genius of this recipe lies in its overnight preparation. By mixing the primary ingredients the night before, you wake up to a ready-to-bake batter, making a quick, warm, and nutritious breakfast or snack entirely feasible, even on the busiest mornings. It’s truly a grab-and-go solution that doesn’t compromise on quality or taste.
- Great Way to Use Leftover Sourdough Discard: For any sourdough baker, managing discard can be a creative challenge. This recipe provides an excellent opportunity to repurpose your unfed sourdough starter, transforming what might otherwise go to waste into a delicious baked good. You can use either an active or inactive (discard) starter to initiate the fermentation of the grains, making it incredibly versatile and sustainable.
- Long Fermented for Better Digestion (if desired): The long fermentation process is more than just a technique; it’s a health-conscious choice. This method helps to break down phytic acid found in grains, which can inhibit nutrient absorption. By reducing phytic acid and partially breaking down gluten, the muffins become easier to digest and their nutrients more bioavailable, making them a gentler option for many, including those with mild gluten sensitivities.
- Master Muffin Recipe: This isn’t just a chocolate chip muffin recipe; it’s a versatile foundation for endless possibilities. While chocolate chips are a classic favorite, feel free to unleash your creativity! Easily swap them out for other delicious add-ins like fresh blueberries, tangy cranberries, sweet raspberries, or even white chocolate chips and nuts. This adaptable recipe encourages experimentation, ensuring you can enjoy a variety of flavors all year round.

Tips For Making This Recipe:
- Understanding Batter Consistency: Since the dry ingredients (flour/grains) undergo an overnight soak with the sourdough starter, the mixture tends to firm up considerably during fermentation. Don’t be alarmed by a thick consistency. The eggs and other wet ingredients are added the next day and require thorough incorporation to achieve a smooth, cohesive batter.
- Mixing Techniques for Optimal Results: For the easiest and best results, I highly recommend using a stand mixer equipped with a paddle attachment. This makes incorporating the eggs into the firm, soaked grain mixture much simpler and more efficient. Alternatively, you can start by using your hands to break up the soaked grains and blend in the eggs; this tactile approach often works surprisingly well to ensure everything is thoroughly combined. Once the initial mixing is done, switching to a whisk can help smooth out any remaining lumps, leading to a wonderfully uniform batter.
- Muffin Flavor Variations: This master recipe is incredibly adaptable! Beyond chocolate chips, consider transforming these into delightful blueberry muffins, warm cinnamon muffins, zesty lemon muffins (with lemon zest and juice), or even incorporating chopped apples or nuts. The possibilities are truly endless, allowing you to customize your muffins to suit any craving or season.
- Efficient Scooping: To ensure evenly sized muffins and a cleaner baking process, an ice cream scoop is your best friend. It dispenses the perfect amount of batter into each muffin tin well, preventing spills and making cleanup a breeze. Plus, it helps all your muffins bake consistently.
- Active Starter vs. Discard: Both active (fed and bubbly) sourdough starter and unfed sourdough discard work beautifully for this recipe. If you’re specifically looking to use up your discard, these sourdough discard muffins are a fantastic solution, adding a subtle tang and contributing to the fermentation process. The key is that the starter (active or discard) provides the beneficial microbes for breaking down the grains.
- Sweetener Alternatives (Sugar vs. Honey): If you prefer to use granulated sugar instead of honey, you certainly can! Simply substitute the honey with an equal amount of sugar. To account for the difference in liquid content, you’ll need to add at least an extra 1/2 cup of sourdough starter to the recipe. If your starter is particularly thick or less hydrated, you might need to add a touch more than 1/2 cup to achieve the desired batter consistency.

FAQ:
How Do I Get A Sourdough Starter?
Embarking on your sourdough journey begins with a healthy starter! The easiest way is to cultivate your own. You can find a comprehensive guide on how I create a quick and easy sourdough starter here, a method I’ve successfully used for years to maintain a vibrant starter. Alternatively, you can often purchase an established starter from local bakeries, order dehydrated starters online, or simply ask a friend who bakes with sourdough if they can share a bit of their active starter with you. Having a reliable starter is the first step to unlocking a world of delicious and digestible baked goods.
Can I use sugar instead of honey?
Absolutely! If honey isn’t your preference or simply unavailable, feel free to substitute it with an equal amount of granulated sugar. When making this swap, it’s important to remember that honey also contributes liquid to the batter. To compensate for this, you’ll need to add approximately 1/2 cup of extra sourdough starter. If your starter tends to be on the thicker side, or if your batter still feels a bit dry, you might need to incorporate a little more than 1/2 cup of starter until you achieve the ideal muffin batter consistency.
Do you have to long ferment this recipe?
While the long fermentation process is highly recommended for its numerous health benefits and enhanced digestibility, it is not strictly mandatory for these muffins to be delicious. You can absolutely mix all the ingredients together and bake them right away for a quicker baking experience. The muffins will still turn out wonderfully moist and flavorful. However, by skipping the long fermentation, you will forgo the advantages of breaking down phytic acid and some gluten, which makes the grains easier on the digestive system and increases nutrient absorption. So, while it’s an optional step for taste, it’s a valuable one for health.
Ingredients:
Crafting these delectable sourdough chocolate chip muffins requires just a handful of straightforward ingredients. Here’s a closer look at what you’ll need and some helpful notes for each:
- Sourdough starter: This is the heart of our recipe. You can use either an active, fed starter, or your unfed sourdough discard. Both will initiate the fermentation of the grains. I typically use a 100% hydration starter, meaning it’s fed equal parts water to flour, which affects the overall moisture content of the batter.
- All-purpose flour: A versatile staple for light and airy muffins. For the best value, consider purchasing in bulk from stores like Costco. For an even more nutritious muffin, you could experiment with a percentage of whole wheat flour, which will further benefit from the long fermentation.
- Butter: Unsalted melted butter contributes richness and moisture. If you prefer to make these dairy-free, readily substitute with an equal amount of coconut oil or avocado oil.
- Honey: Our natural sweetener of choice, providing a delicate flavor profile. Maple syrup is a fantastic alternative if you prefer, or as noted in our FAQ and tips, granulated sugar can also be used with a slight adjustment to the starter quantity.
- Eggs: Act as a binder and add structure and richness to the muffins, ensuring a tender crumb.
- Baking soda: Works with the acidity of the sourdough to create lift and a fluffy texture, giving our muffins their desirable dome.
- Salt: A crucial flavor enhancer that balances the sweetness and deepens the overall taste of the muffins.
- Vanilla extract: Whether homemade or store-bought, a good quality vanilla extract adds a warm, aromatic depth to the chocolate and sourdough flavors.
- Chocolate chips: Mini chocolate chips are my personal favorite as they distribute evenly throughout the muffin, ensuring chocolate in every bite. However, regular-sized chocolate chips or even chocolate chunks will work wonderfully, offering delightful pockets of melted chocolate.
Tools you may need:
Having the right tools can make your baking experience smoother and more enjoyable:
- Muffin tin: A standard 12-cup muffin tin is essential for baking these delightful treats.
- Stand mixer with paddle attachment: While not strictly required, a stand mixer greatly simplifies the mixing process, especially when incorporating ingredients into the thickened fermented dough. A hand mixer or even just a large mixing bowl and strong arms will also work.
- Whisk: Perfect for smoothing out the batter and ensuring all ingredients are well combined.
- Silicone spatula: Ideal for scraping down the sides of the bowl, ensuring no ingredient is left unmixed, and for gently folding in chocolate chips.
- Measuring cups (liquid and dry) and spoons: Accurate measurements are key to successful baking.
- Ice cream scoop (optional, but really useful): A standard ice cream scoop is excellent for portioning out muffin batter evenly into the muffin tin, making for uniform muffins and a tidier process.
- Muffin liners: These make for easy removal of the muffins from the tin and simpler cleanup. Alternatively, you can thoroughly grease the muffin tin wells.

How To Make Long Fermented Sourdough Chocolate Chip Muffins
Embrace the magic of overnight fermentation for these delightful muffins. Here’s a detailed guide to creating fluffy, digestible sourdough chocolate chip muffins:
- Evening Prep (Fermentation Start): In a spacious large bowl, or the bowl of your stand mixer, combine the melted butter, honey, all-purpose flour, and your sourdough starter (whether active or discard). Mix these ingredients thoroughly until just combined. The mixture will be quite thick, and it will firm up even more as it ferments overnight. Depending on the hydration level of your starter (mine is 100% hydration, meaning equal parts water to flour), you might need to add a mere touch of water if the dough seems excessively stiff. Cover the bowl snugly with plastic wrap or a clean kitchen towel and allow it to ferment at room temperature for 12 to 24 hours. This crucial step allows the sourdough to predigest the grains, unlocking nutrients and flavor.
- Morning Prep (Baking Day): The next day, after the fermentation period, preheat your oven to 375 degrees Fahrenheit (190°C). Prepare your muffin tin by lining each well with cupcake liners or by greasing them thoroughly to prevent sticking.
- Adding Final Ingredients: Uncover your bowl of fermented muffin batter. Now, add the vanilla extract, baking soda, eggs, and salt to the mixture.
- Mixing the Batter: Begin mixing all the ingredients together. This is where a stand mixer with a paddle attachment truly shines, making the process significantly easier and ensuring a homogenous batter. You’ll notice the batter is quite firm initially, which is completely normal due to the soaked grains. I often start by using my clean hands to break up any large clumps and really work the eggs into the thick batter, ensuring everything is well integrated.
- Incorporating Chocolate Chips: Once the batter begins to come together and is mostly smooth, gently fold in the chocolate chips. Switch to a whisk at this stage to thoroughly combine everything and break up any remaining small lumps, achieving a smooth and evenly dispersed batter.
- Filling the Muffin Tins: Using an ice cream scoop (for even sizing and less mess) or a spoon, distribute the batter equally among the prepared muffin wells. Fill each well about two-thirds full to allow for proper rising.
- Baking: Place the muffin tin into your preheated oven and bake for 20-25 minutes. The muffins are ready when their tops turn a beautiful golden brown and a toothpick inserted into the center of a muffin comes out clean. This indicates they are fully cooked through.
- Cooling: Once baked, carefully remove the muffin tin from the oven. Allow the muffins to cool in the tin for a few minutes before transferring them to a wire cooling rack. Alternatively, you can flip them onto a plate to cool completely. Cooling on a rack helps prevent the bottoms from becoming soggy.

Quick Sourdough Discard Chocolate Muffins:
If you’re short on time or prefer not to long ferment, you can still enjoy delicious sourdough muffins! This quick method uses sourdough discard for flavor and texture without the overnight wait.
- Preheat your oven to 375 degrees F (190°C). Prepare a 12-cup muffin tin by greasing it well or lining it with muffin liners.
- In a stand mixer with a paddle attachment, or a large mixing bowl, combine the oil (if using instead of melted butter) and sugar. Mix thoroughly on medium speed until light and fluffy.
- Add the remaining wet ingredients: eggs, vanilla extract, and sourdough starter. Mix until all ingredients are well combined and the batter is smooth.
- Gradually mix in the dry ingredients (flour, baking soda, salt) until just combined. Be careful not to overmix, as this can lead to tough muffins.
- Gently fold in the chocolate chips using a silicone spatula until they are evenly distributed throughout the batter.
- Spoon the batter evenly into each muffin well, filling them about two-thirds full.
- Bake for 20-25 minutes, or until the tops of the muffins are golden brown and a toothpick inserted into the center comes out clean.
- Allow the muffins to cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
- Enjoy your quick sourdough discard chocolate chip muffins!

Storage:
These sourdough chocolate chip muffins are best enjoyed fresh, but they also store beautifully for future enjoyment. To keep them fresh at room temperature, place them in an airtight container or a sealed storage bag. They will remain delicious for up to three days. For longer storage, these muffins freeze exceptionally well. Simply place cooled muffins in a freezer-safe bag or container and freeze for up to three months. When you’re ready to enjoy, thaw them at room temperature or gently warm them in the microwave or oven for a fresh-baked taste.
