If you’ve mastered basic sourdough but want to explore richer flavors, chocolate bagels are the perfect next challenge. These overnight bagels develop complex cocoa notes while maintaining that signature chewy sourdough texture. The long, cold fermentation deepens the flavor while fitting easily into a busy schedule–you do the work when it suits you, and the dough does the rest overnight.
How to Make Overnight Double Chocolate Sourdough Bagels
This recipe creates 6-8 bagels with rich chocolate flavor from two sources: cocoa powder mixed into the dough plus melted chocolate pieces folded in for chocolate pockets throughout.
Ingredients
- 1 cup active sourdough starter (fed 4-8 hours prior, bubbly and at peak)
- 1.5 cups warm water
- 3.5 cups bread flour
- 2 tablespoons unsweetened cocoa powder
- 2 teaspoons salt
- 1.5 tablespoons sugar or honey
- 1 cup semi-sweet or dark chocolate chips or chunks
Method
Mix the dough base
Combine your active starter with warm water in a large bowl, stirring until mostly dissolved. Add bread flour and cocoa powder, mixing until no dry flour remains. Let this mixture rest for 30 minutes (autolyse phase) to fully hydrate the flour.
Incorporate salt and chocolate
After the rest, sprinkle salt over the dough and fold it in gently using a dough scraper. Work the dough for 2-3 minutes until salt is fully incorporated. Fold in chocolate chips or chunks in two additions, distributing them evenly throughout.
Build strength with stretch and folds
Transfer dough to a lightly oiled container. Over the next 2-3 hours at room temperature, perform 4-5 sets of stretch and folds (every 30-40 minutes). Wet your hand, grab one side of the dough, stretch it up and fold it over itself, rotate the bowl, and repeat from all four directions.
Shape into a round for first rise
Once the dough appears puffy with visible bubbles and holds shape better, turn it out onto a lightly floured surface. Gently shape it into a round, handling it minimally to retain air. Place the round seam-side up in a floured banneton basket or bowl lined with a kitchen towel.
Cold ferment overnight
Cover the basket with plastic wrap or place it in a plastic bag. Refrigerate for 12-16 hours. During this time, flavor develops and gluten continues to strengthen. The cold slows fermentation dramatically, making timing more forgiving.
Divide and pre-shape bagels
Remove dough from refrigerator and turn it out onto a clean surface. Using a dough scraper or bench knife, divide into 6-8 equal pieces (weigh if possible for consistency). Pre-shape each piece into a loose round, cover with a towel, and rest for 15-20 minutes.
Shape final bagel form
For each piece, poke a hole in the center with your thumb or a 2-inch round cutter. Gently stretch the dough into a ring, working evenly so the hole expands to about 2 inches in diameter and the thickness is uniform. Aim for a donut shape with a hole you can fit two fingers through.
Proof, boil, and bake
Place shaped bagels on parchment paper with space between them. Let rise at room temperature for 45-90 minutes (they should puff slightly but not fully double). Bring a pot of water to boil with a tablespoon of sugar or honey. Boil each bagel 30-45 seconds per side, then place on a lined baking sheet. Bake at 425F for 22-25 minutes until deep golden brown.
- Feed your starter 4-8 hours before mixing so it’s at peak activity with visible bubbles–this gives the dough the best rise and flavor development.
- Chocolate chunks work better than chips for bagels because they hold their shape during boiling; if chips break apart, they can cloud the boiling water.
- Don’t skip the overnight cold ferment–it’s what develops the complex flavor that makes sourdough special. Room temperature proofing alone produces flatter, less flavorful results.
What to Look For in Bagel-Making Equipment
- Dough scraper or bench knife: A flat, rectangular tool is essential for dividing dough, shaping, and cleaning your work surface. Look for stainless steel with comfortable handle; it makes bagel shaping significantly cleaner and faster.
- Kitchen scale: Bagel shaping benefits from consistency. A scale lets you divide dough into equal pieces so all bagels proof and bake at the same rate, producing uniform results.
- Banneton proofing basket: This lined basket supports dough during cold fermentation and overnight proof, preventing spreading. A 10-inch round basket is ideal for the bulk fermentation and shaping stage.
- Large boiling pot or Dutch oven: You need sufficient water depth and width to submerge bagels briefly without crowding. A 6-8 quart capacity ensures proper boiling without water sloshing over as you work.

Overnight double chocolate sourdough bagels seem intimidating if you’re new to bagel-making, but the process is surprisingly forgiving. Most of the time is passive–the dough ferments while you sleep. You need perhaps 30 minutes of actual hands-on work spread across two days. A dough scraper and kitchen scale transform the experience from messy and frustrating to clean and precise. Start with quality chocolate; the bagels are only as good as your ingredients.
The magic happens in the overnight cold fermentation. That 12-16 hour rest in the refrigerator isn’t just a scheduling convenience–it’s where sourdough develops its signature flavor and that dense, chewy texture that homemade bagels are known for. Your first batch might not be perfect, and that’s fine. Each time you make them, you’ll develop a feel for the dough, your equipment, and your kitchen’s temperature. By the third or fourth batch, you’ll be producing bagels that rival anything from a bagel shop.
Frequently Asked Questions
Can I use all-purpose flour instead of bread flour?
You can, but bread flour produces chewier bagels because of its higher protein content. All-purpose flour will work but may yield softer, less chewy results. For chocolate bagels specifically, bread flour’s structure better supports the weight and moisture of melted chocolate throughout the crumb.
What if my starter isn’t very strong or active?
A weak starter will result in sluggish fermentation and flatter bagels. Feed your starter at least twice in the 12-24 hours before baking, discarding half each time. Use it when it shows visible bubbles and has nearly doubled in volume. If time is short, consider extending the overnight cold fermentation to 16-18 hours to compensate.
Do I have to boil the bagels, or can I just bake them?
Boiling is essential–it gelatinizes the starch on the exterior, creating the characteristic chewy crust and dense crumb. Unbaked bagels will rise too much in the oven and become bread-like rather than bagel-textured. The brief 30-45 second boil per side is what distinguishes bagels from other yeasted doughs.
How do I store leftover bagels?
Cool completely on a wire rack, then slice and freeze in a freezer bag for up to 3 months. Thaw at room temperature or toast from frozen. Store at room temperature in a sealed container for 2-3 days, but they’ll gradually become stale. Freezing preserves that fresh-baked chewiness far better than refrigeration.
Can I make the dough and bagels without sourdough starter?
Sourdough starter is central to the flavor and fermentation of this recipe. You could substitute with commercial yeast, but you’d lose the complex sour notes that make these bagels special. If you don’t have a starter, consider building one (5-7 days) or sourcing some from a local baker before attempting this recipe.
