Some of my happiest baking memories involve chocolate and a slow Sunday morning. This chocolate chip kefir sourdough bread came from wanting that same cozy feeling in a loaf I could slice for breakfast, not just a treat for dessert. Using kefir in the dough gives it a soft tang that plays beautifully against the sweetness of the chocolate, the same way I use kefir in so many of my other bakes.

This loaf sits right between bread and dessert. It has the chewy, open crumb of a true sourdough, but with pockets of melted dark chocolate in every slice. My family asks for this one on weekends more than almost anything else I bake, and once you try a warm slice with the chocolate still soft, you will understand why.
Why This Recipe Works
- Kefir adds gentle tang. The natural sourness in kefir balances the sweetness of the chocolate so the loaf never feels like plain cake.
- Rich chocolate in every bite. Chocolate chips are folded through the whole loaf, not just the top, so every slice gets its share.
- Naturally fermented. No commercial yeast, just a slow rise that builds real sourdough flavor and a chewy texture.
- Works for breakfast or dessert. Toasted with butter in the morning, or warmed with a scoop of ice cream at night.
Basic Equipment You’ll Need
- Kitchen scale – for accurate flour, kefir, and water measurements
- Large mixing bowl – for mixing and bulk fermentation
- Dutch oven – traps steam for a crisp, golden crust
- Banneton or bowl lined with a towel – holds the loaf’s shape while it rests
- Bench scraper – helps handle and shape the dough
- Lame or sharp razor blade – for scoring the top of the loaf
- Parchment paper – makes it easy to lower the dough into the hot Dutch oven
- Wire cooling rack – lets air flow under the loaf as it cools

Chocolate Chip Kefir Sourdough Bread
Ingredients
Equipment
Method
- 1: Mix the dough: In a large bowl, whisk 150 grams plain whole milk kefir, 200 grams water, and 100 grams active sourdough starter together. Add 500 grams bread flour and 40 grams brown sugar. Mix until no dry flour remains. Cover and rest 30 minutes (autolyse).
- 2: Add salt: Sprinkle 10 grams fine sea salt over the dough. Pinch and fold until fully worked in. Cover and rest 30 minutes.
- 3: Stretch and fold: Do 3 sets of stretch and folds, 90 minutes apart. Turn the bowl and fold each side into the middle each time.
- 4: Add chocolate chips: Toss 140 grams dark chocolate chips in 1 tablespoons extra flour for tossing chocolate chips. Press the dough into a rectangle, scatter on the chocolate chips, then fold and do one more stretch and fold to distribute evenly.
- 5: Bulk ferment: Cover the dough and let it rise at room temperature until it grows by about 50%. This takes 4 to 270 minutes, depending on how warm your kitchen is.
- 6: Shape the loaf: Turn the dough onto a lightly floured surface. Shape into a round or oval loaf. Place seam-side up in a floured banneton or bowl lined with a towel.
- 7: Cold retard overnight: Cover the banneton and place it in the fridge for 8 to 480 minutes. This builds flavor and makes the dough easier to score.
- 8: Preheat and score: Preheat your oven to 450°F (230°C) with a Dutch oven inside for 30 minutes. Turn the cold dough onto parchment paper. Score the top with a sharp blade.
- 9: Bake: Place the dough into the hot Dutch oven with the lid on. Bake 45 minutes covered, then remove the lid and bake 20 to 25 minutes more, until deep golden brown.
- 10: Cool completely: Move the loaf to a wire rack. Let it cool for at least 60 minutes before slicing. Cutting too early makes the inside gummy.
Notes
Recipe Details
Why Use Kefir Instead of Water
Kefir adds moisture and a gentle tang that plain water cannot. It works alongside your sourdough starter, not in place of it — the starter is still what makes the bread rise. Use plain, unsweetened whole milk kefir for the best balance of flavor.
Choosing Your Chocolate Chips
Dark chocolate chips give the best contrast against the tangy dough, since their slight bitterness balances the sourdough flavor. If you prefer a sweeter loaf, semisweet chips work well too. Freezing the chocolate chips for about 10 minutes before folding them in helps them hold their shape in the warm dough instead of melting too early.
Why the Dough Rests So Long
Sourdough relies on wild yeast in your starter, which works much slower than store-bought yeast. This slow rise is what gives the bread its tangy flavor and chewy texture, and it gives the chocolate time to settle evenly through the crumb. Do not rush this step, even on a warm day.
Storing Your Loaf
- Room temperature: Keep in a paper bag or bread box for up to 2 days.
- Fridge: Wrap tightly and store up to 1 week, though the crust will soften.
- Freezer: Slice first, then freeze in a sealed bag for up to 3 months. Toast slices straight from frozen.
Ways to Serve It
Toast a slice and let the chocolate chips go soft and melty, or serve it slightly warm with a scoop of vanilla ice cream for a simple dessert. It also pairs beautifully with a cup of coffee for a weekend breakfast.

Recipe Notes
- Use plain, unsweetened whole milk kefir for the best flavor balance. Flavored kefir will make the loaf overly sweet.
- Freeze the chocolate chips for about 10 minutes before folding them into the dough so they hold their shape during baking.
- Make sure your sourdough starter is active and bubbly before you begin. It should double in size within 4 to 6 hours of feeding.
- Do not skip the cold retard step. Resting the shaped dough in the fridge overnight makes it easier to score and deepens the flavor.
- Let the loaf cool for at least 1 hour before slicing so the inside doesn’t turn gummy.
- Store the baked loaf at room temperature in a paper bag for 2 days, or freeze sliced for up to 3 months.

Frequently Asked Questions
Can I use milk chocolate chips instead of dark chocolate?
Yes, though the loaf will taste sweeter overall. Dark chocolate is recommended because its slight bitterness balances the tang from the kefir and sourdough starter.
Why did my chocolate chips melt into streaks instead of staying whole?
This usually happens when the chips are added to warm dough or handled too much. Freeze the chips for about 10 minutes before folding them in, and handle the dough gently.
Can I use plain yogurt instead of kefir in this recipe?
Kefir is thinner than yogurt and gives the dough a different hydration level and flavor. If you only have yogurt, thin it with a little water first, though the tang will be milder.
Do I need a Dutch oven to bake this bread?
A Dutch oven traps steam and gives the best crust, but you can also bake on a hot baking sheet with a pan of water in the oven to create steam.
Why is my sourdough bread dense instead of airy?
Dense bread is often a sign of an underfed or weak starter, or not enough bulk fermentation time. Make sure your starter doubles in size before you start, and let the dough rise until it looks puffy and full of air pockets.
How do I know when bulk fermentation is done?
The dough should look about 50% bigger, feel light and jiggly when you shake the bowl, and show small bubbles on the surface. Watch the dough, not the clock, since timing changes with kitchen temperature.
