Ingredients You’ll Need
The magic of this S’mores Sourdough Bread Recipe lies in its straightforward ingredients, each playing a vital role. From the sturdy structure given by bread flour to the sweet bursts from chocolate chips and marshmallows, these components come together effortlessly to create something truly special.
- Bread flour (500 grams): Provides the perfect protein content for a chewy and airy crumb texture in your sourdough.

- Active sourdough starter (50 grams): The natural leavening agent that gives this bread its signature tang and rise.
- Salt (10 grams): Enhances flavor and strengthens the gluten structure.
- Sugar (50 grams): Adds a touch of sweetness and helps with browning of the crust.
- Chocolate chips (100 grams): Melt into pockets of indulgence, delivering the classic s’mores chocolate note.
- Marshmallows (60 grams): Stirred into the dough for those delightful gooey portions throughout the bread.

How to Make S’mores Sourdough Bread Recipe
Step 1: Mix Your Dough
Start by combining bread flour, water, your active sourdough starter, sugar, and salt in a large mixing bowl. Stir just until a rough, shaggy dough forms—don’t worry about perfection yet! This initial mixing sets the stage for the gluten structure and flavor foundation of your bread. After mixing, cover and let the dough rest for about 30 minutes; this allows the flour to fully hydrate.
Step 2: Stretch, Fold, and Add Sweetness
After the rest, perform a gentle stretch and fold to begin developing the gluten network while integrating some air. At this point, gently fold in the chocolate chips and marshmallows. Be careful to distribute them evenly without melting the marshmallows into the dough. This step combines structure-building with the signature sweet and melty inclusions.
Step 3: Repeat Rest and Fold
Let the dough rest another 30 minutes and perform another round of stretch and folds. This repetition strengthens the dough further, ensuring it can hold up the weight of those buttery, sweet treats baked inside.
Step 4: Bulk Fermentation Overnight
Allow your dough to ferment at room temperature for 10 to 14 hours. This slow fermentation deepens flavor complexity, encourages natural sourness, and helps with rise. Watch for a bubbly, slightly risen dough that’s lively and ready for shaping.
Step 5: Prepare the Graham Cracker Topping
While your dough ferments, melt the unsalted butter and mix it with the crushed graham crackers. This luscious, buttery topping will add that classic crunchy texture and sweet flavor that makes this S’mores Sourdough Bread Recipe so irresistible.
Step 6: Shape and Layer
Carefully shape your dough into a square on a floured surface, then spread the graham cracker butter mixture evenly over the top. Fold the dough to enclose the topping, then place it into a lightly floured proofing basket. This layering is what creates those iconic s’mores pockets within your loaf.
Step 7: Cold Proof in the Fridge
Place the shaped dough in the refrigerator for at least 8 hours of cold proofing. This slow chill enhances the flavor and allows the crust to develop a richer color during baking, transforming your bread’s taste and appearance dramatically.
Step 8: Preheat Your Oven
Preheat your oven with a Dutch oven inside to 450℉. This method ensures a hot, steamy environment perfect for sourdough baking, helping your loaf develop a crackly crust and airy interior. The Dutch oven mimics a professional bread oven’s conditions for stunning results.
Step 9: Score and Bake
Remove the dough from the fridge, carefully transfer it onto parchment paper, and score the top as you like—it helps control how the bread expands while baking. Bake covered in the Dutch oven for 30 minutes, then uncover and bake an additional 10 to 15 minutes until golden brown and irresistible.
How to Serve S’mores Sourdough Bread Recipe
Garnishes
A light dusting of powdered sugar or a drizzle of melted chocolate can enhance the sweet allure of this bread. For a fun touch, sprinkle a few extra crushed graham crackers on top just before serving—you’ll add a vibrant texture contrast and a touch of rustic charm.
Side Dishes
This bread pairs beautifully with a cozy cup of hot cocoa or coffee, perfect for breakfast or an afternoon snack. It’s also divine served alongside vanilla ice cream or a dollop of whipped cream for a dessert experience that surprises and delights.
Creative Ways to Present
Try serving this bread warm with a small pot of marshmallow fluff or chocolate sauce for dipping—almost like an interactive dessert board. You can also cut it into thick slices and toast them lightly to bring out the chocolate’s aroma and soften the marshmallows further for maximum gooeyness.
Make Ahead and Storage
Storing Leftovers
Store leftover slices in an airtight container at room temperature for up to two days. The bread’s soft marshmallow centers and chocolate chips may slightly firm up but will maintain their delicious flavor and texture.
Freezing
If you want to keep your S’mores Sourdough Bread Recipe fresh for longer, wrap it tightly in plastic wrap and then foil, and place it in the freezer. It stays at its best for up to 3 months. When ready, thaw it at room temperature or toast slices directly from frozen.
Reheating
Reheat slices gently in a toaster oven or regular oven at a low temperature to revive the melty goodness and crisp the crust slightly. Avoid microwaving, as it can make the marshmallows chewy and the crust soggy.
FAQs
Can I use a sourdough starter that’s not very active?
For the best rise and flavor in this S’mores Sourdough Bread Recipe, your starter should be active and bubbly. If it’s sluggish, feed it a few times before baking to ensure it has plenty of leavening power.
What type of chocolate chips work best?
Use good-quality semi-sweet or dark chocolate chips for a rich contrast to the sweet marshmallows. Avoid milk chocolate as it melts too fast and can make the dough overly sticky.
Can I substitute homemade graham crackers?
Absolutely! If you have a favorite homemade graham cracker recipe, they will add a special touch to this recipe. Just crush them finely to maintain the right texture for mixing and topping.
Is it possible to make this bread without a Dutch oven?
You can bake the loaf on a preheated baking stone or heavy sheet pan and place a pan of hot water in the oven to create steam. It won’t be exactly the same but can still yield a lovely crust and flavor.
How do I prevent marshmallows from melting too much inside the dough?
Fold the marshmallows in gently during the last stretch and fold stage and keep the dough cool when possible. This helps them retain some shape and prevents them from melting into a sticky mess.
Final Thoughts
This S’mores Sourdough Bread Recipe is a delightful way to infuse your baking with a little seasonal magic and childhood nostalgia. Its perfect balance of flavors and textures will bring smiles and warm memories to your table. Trust me, once you make this bread, it will become a beloved favorite you’ll want to bake again and again.

Ingredients
Dough Ingredients
- 500 grams bread flour
- 350 grams water
- 50 grams active sourdough starter
- 10 grams salt
- 50 grams sugar
Mix-ins
- 100 grams chocolate chips
- 60 grams marshmallows
Graham Cracker Topping
- 56 grams unsalted butter
- 4 crushed graham crackers
Instructions
- Mix Dough: In a large mixing bowl, combine bread flour, water, active sourdough starter, sugar, and salt until a shaggy dough forms. Cover and let it rest for 30 minutes to allow the flour to hydrate fully.
- Incorporate Mix-ins: Perform a stretch and fold technique on the dough to start gluten development. Gently fold in the chocolate chips and marshmallows without deflating the dough.
- Develop Gluten: Let the dough rest for another 30 minutes, then repeat the stretch and fold process to further develop the gluten structure, ensuring a good crumb texture.
- Bulk Fermentation: Allow the dough to ferment at room temperature for 10 to 14 hours. This long fermentation enhances flavor and creates a light, airy bread.
- Prepare Graham Cracker Topping: Melt the unsalted butter and mix thoroughly with crushed graham crackers until well combined, creating a sticky, buttery topping.
- Shape and Add Topping: Turn the dough out onto a lightly floured surface and shape into a square. Spread the graham cracker butter mixture evenly over the dough’s surface, then fold the dough over itself to enclose the topping. Place shaped dough into a proofing basket for support.
- Cold Proof: Refrigerate the dough in the proofing basket for at least 8 hours. This delayed proof improves flavor and dough strength.
- Preheat Oven and Dutch Oven: About 30 minutes before baking, preheat your oven to 450°F (232°C) with a Dutch oven inside to ensure it’s thoroughly heated for baking.
- Score and Bake: Carefully remove the dough from the fridge, score the top with a sharp blade to allow expansion, then place it into the hot Dutch oven. Bake covered for 30 minutes to create steam for a crisp crust.
- Finish Baking Uncovered: Remove the lid and continue baking the bread for an additional 10 to 15 minutes, or until the crust turns a rich golden brown with a slight caramelization from the sugar and butter.
Notes
- Use an active, bubbly sourdough starter for best fermentation results.
- The stretch and fold technique helps develop gluten without kneading.
- Refrigeration during cold proof slows fermentation and enhances flavor complexity.
- Use a Dutch oven to trap steam, creating a moist environment for a crispy crust.
- Allow the bread to cool completely before slicing to set the crumb and avoid gummy texture.
