Ingredients & Substitutions
Achieving the perfect Custard-Filled Chocolate Chip Brioche relies on specific, high-quality ingredients. Each element serves a vital culinary purpose in building flavor and structure. Ensure your dairy and eggs are at the right temperature before beginning.
For the Brioche Dough
3 ½ cups (420g) Bread Flour: Bread flour provides the high protein content necessary to develop strong gluten. This ensures your buns hold their shape while remaining incredibly fluffy.
¼ cup (50g) Granulated Sugar: A touch of sugar lightly sweetens the dough and feeds the yeast. It also helps achieve that beautiful golden-brown exterior during baking.
1 packet (7g) Active Dry Yeast: Yeast acts as the invisible foundational ingredient responsible for the dough’s rise. Always ensure your yeast is fresh so your buns become light and airy.
1 tsp (5g) Fine Sea Salt: Salt is crucial for controlling yeast fermentation and tightening the gluten structure. It also enhances the rich, buttery flavor of the brioche.
½ cup (120ml) Whole Milk (Warm): Warm milk hydrates the dough and activates the yeast. Using whole milk adds essential milk fat, keeping the crumb tender.
4 Large Eggs (Room Temperature): Eggs provide structure, richness, and hydration to the dough. Using room temperature eggs ensures they incorporate seamlessly without chilling the butter.
¾ cup (170g) Unsalted Butter (Softened): Butter is the heart of any brioche, providing unparalleled richness and a melt-in-your-mouth texture. It must be gradually kneaded into the dough for proper emulsification.
For the Vanilla Custard & Inclusions
2 cups (480ml) Whole Milk: Whole milk serves as the luscious base for your pale yellow vanilla custard. Avoid skim milk, as the fat is needed for a creamy mouthfeel.
6 Large Egg Yolks: Egg yolks thicken the custard and provide its signature pale yellow color. They also add a rich, velvety texture that pairs perfectly with the bread.
½ cup (100g) Granulated Sugar: Sugar sweetens the custard while helping to stabilize the egg yolks during the tempering process. It ensures a smooth, silky finish.
¼ cup (30g) Cornstarch: Cornstarch is the thickening agent that gives the custard enough structure to be piped into the sliced buns. It ensures the filling won’t run out when you take a bite.
1 tbsp (15ml) Pure Vanilla Extract: A high-quality vanilla extract or vanilla bean paste flavors the custard beautifully. This creates a fragrant, aromatic profile that offsets the chocolate.
1 ½ cups (250g) Mini Semi-Sweet Chocolate Chips: Mini chips are crucial because they distribute evenly throughout the custard without weighing it down. You will also use these to sprinkle generously on top of the buns.
1 Large Egg + 1 tbsp Milk (For Egg Wash): Brushing the dough with an egg wash before baking is mandatory. This is exactly how you achieve a deeply glossy, golden-brown crust.
Equipment Needed
- Stand Mixer with Dough Hook: Essential for properly kneading the butter into the brioche dough without overheating it.
- Medium Saucepan: Needed for gently cooking and thickening the vanilla custard.
- Piping Bag (Optional): Makes filling the sliced buns with custard clean and visually appealing.
- Parchment-Lined Baking Sheet: Prevents the sticky dough and bottom chocolate chips from adhering to the pan.
- Instant-Read Thermometer: Helpful for ensuring your milk is perfectly warm (110°F/43°C) for the yeast.
Step-by-Step Instructions
Creating professional-quality brioche requires patience and precise technique. Follow these steps closely to ensure your dough rises beautifully and your custard thickens perfectly. Pay attention to the sensory cues to know exactly when to move to the next phase.
1. Make the Vanilla Custard
In a medium saucepan, heat the 2 cups (480ml) of whole milk over medium heat until it begins to steam. Do not let it reach a rolling boil. Meanwhile, in a separate bowl, vigorously whisk the egg yolks, granulated sugar, and cornstarch until pale and smooth.
Slowly pour the warm milk into the egg yolk mixture while whisking constantly to temper the eggs. Pour the entire mixture back into the saucepan and cook over medium-low heat. Whisk continuously until the custard bubbles and thickens into a creamy, pale yellow pudding-like consistency.
Remove from heat and stir in the pure vanilla extract. Transfer the custard to a clean bowl and press a piece of plastic wrap directly onto the surface to prevent a skin from forming. Chill in the refrigerator for at least 2 hours until completely set.
2. Prepare the Brioche Dough
In the bowl of a stand mixer, combine the warm milk, yeast, and a pinch of sugar. Let it sit for 5-10 minutes until it smells yeasty and looks frothy. Add the bread flour, remaining sugar, salt, and room-temperature eggs.
Mix on low speed with a dough hook until the dough comes together into a rough, shaggy mass. Increase the speed to medium and knead for about 5 minutes until the dough begins to build strength. It should start pulling away from the sides of the bowl.
With the mixer running, add the softened butter one tablespoon at a time. Wait until each piece is fully incorporated before adding the next. Once all the butter is added, knead for another 10-15 minutes until the dough passes the windowpane test, meaning it can stretch thin enough to let light through without tearing.
3. Proofing and Shaping the Buns
Form the dough into a smooth ball, place it in a lightly greased bowl, and cover it with a damp towel. Let it rise in a warm, draft-free spot for 1.5 to 2 hours, or until doubled in size. The dough should look puffed and feel incredibly soft to the touch.
Punch down the dough to release the air and divide it into 8 equal portions. Roll each portion into a tight, smooth ball and place them onto a parchment-lined baking sheet. Gently press a small handful of mini chocolate chips into the top of each bun.
Cover the baking sheet loosely with plastic wrap and let the buns undergo their second proof for 45-60 minutes. They should appear visibly swollen and jiggle slightly when you gently shake the pan.
4. Bake to a Glossy Golden-Brown
Preheat your oven to 350°F (175°C). In a small bowl, whisk together 1 egg and 1 tablespoon of milk to create the egg wash. Gently brush the tops and sides of the proofed buns, being careful not to deflate them.
Bake the buns in the center of the oven for 20-25 minutes. Watch for the sensory cue: you want a deeply glossy, golden-brown crust to form all over. The kitchen will smell intensely of toasted butter and baking bread.
Remove the buns from the oven and transfer them immediately to a wire rack. Allow them to cool completely to room temperature. Slicing warm brioche will cause the crumb to compress and become gummy.
5. Fill and Assemble
Once the buns are completely cool, use a serrated knife to slice each bun in half horizontally. Open them up to reveal the soft, airy interior crumb.
Remove your chilled vanilla custard from the fridge and give it a vigorous whisk to smooth it out. Fold 1 cup (170g) of the mini semi-sweet chocolate chips directly into the pale yellow custard, packing it full of chocolate.
Generously spoon or pipe a thick layer of the chocolate chip-packed custard onto the bottom half of each bun. Place the top half of the bun right over the custard. Serve immediately on a white ceramic plate to recreate that flawless, food-magazine presentation.
Expert Tips for Success
- Room Temperature Ingredients: Always use room temperature eggs and butter. Cold butter will not emulsify into the dough, leaving you with greasy, dense buns.
- The Windowpane Test: Do not rush the kneading process. If the dough tears immediately when stretched, keep kneading until the gluten structure is fully developed.
- Temper the Yolks: When making the vanilla custard, add the hot milk to the yolks very slowly. Rushing this step will result in scrambled eggs instead of a silky cream.
- Cool Completely: Never fill warm brioche with custard. The residual heat will melt the custard and turn your beautifully baked bun into a soggy mess.
Storage & Reheating/Freezing
Because this recipe contains a dairy-rich vanilla custard, the assembled buns must be stored in the refrigerator. Place them in an airtight container where they will stay fresh for up to 3 days. The brioche will firm up slightly in the cold, so let them sit at room temperature for 15 minutes before eating.
If you want to make elements ahead of time, you can freeze the baked, unfilled brioche buns for up to 2 months. Wrap them tightly in plastic wrap and thaw them at room temperature. The custard does not freeze well, as the cornstarch will break and weep upon thawing, so it must be made fresh.

Frequently Asked Questions
It is best to freeze the baked brioche buns empty. Custard does not freeze well due to the cornstarch, which can separate and weep when thawed. Thaw the buns at room temperature, then slice and fill with fresh custard.
Yes, you can make the vanilla custard up to two days in advance. Keep it stored in an airtight container in the refrigerator with plastic wrap pressed directly against the surface to prevent a skin from forming.
While homemade vanilla custard provides the best flavor and structural thickness, you can substitute a high-quality, thick store-bought pastry cream in a pinch. Avoid thin puddings, as they will seep into the bread.
The key to a glossy, professional-looking crust is a proper egg wash. Whisk together one whole egg with a tablespoon of milk, and gently brush it over the proofed buns right before baking.
Brioche dough won’t rise if your yeast is expired, or if the milk used to activate it was too hot (over 115°F/46°C), which kills the yeast. Make sure to let the dough proof in a warm, draft-free environment.
