Ingredients
Instructions
1. Combine the Wet Ingredients: In a large mixing bowl, whisk together the active sourdough starter, warm milk, granulated sugar, one large egg, egg yolk, and vanilla extract (if using). Make sure the sugar is mostly dissolved.
2. Add Dry Ingredients: Gradually add the all-purpose flour and salt to the wet mixture. Mix with a wooden spoon or your hands until a shaggy dough forms. It will look a bit rough and sticky at this stage.
3. Initial Kneading and Butter Incorporation: Turn the dough out onto a lightly floured surface. Knead for about 5 minutes until it starts to come together. Then, begin adding the softened butter, one piece at a time, kneading each piece in fully before adding the next. This process might seem messy at first, but keep going!
4. Develop the Dough: Continue kneading the dough for another 10-15 minutes until it becomes smooth, elastic, and passes the “windowpane test” (you can stretch a small piece thin enough to see light through it without tearing). Place the dough in a lightly oiled bowl, cover it with plastic wrap or a damp towel, and let it rise in a warm place for 4-6 hours, or until doubled in size. Alternatively, you can refrigerate it overnight for a slower, more flavorful rise.
5. Shape the Buns: Gently punch down the risen dough to release the air. Turn it out onto a lightly floured surface and divide it into 12 equal pieces. Roll each piece into a smooth, tight ball. Arrange the shaped buns in a greased 9×13 inch baking pan, leaving a little space between them.
6. Second Rise and Preheat Oven: Cover the pan loosely with plastic wrap or a damp towel and let the buns proof in a warm place for 1-2 hours, or until they look puffy and have nearly doubled in size. Towards the end of the proofing time, preheat your oven to 375 F (190 C).
7. Egg Wash and Bake: Once the buns are fully proofed, gently brush the tops with the beaten egg wash. If desired, sprinkle with coarse sea salt or sesame seeds. Bake for 20-25 minutes, or until the tops are golden brown and the internal temperature reaches 200-205 F (93-96 C) when checked with an instant-read thermometer.
8. Cooling: Remove the pan from the oven and let the buns cool in the pan for 10 minutes before transferring them to a wire rack to cool completely.

It’s a fantastic way to use your sourdough discard or active starter, creating something truly delicious that your family will rave about.
Everything You Need To Make This Recipe Without Stress
Gathering your ingredients before you begin is the best way to ensure a smooth baking experience. This recipe uses common pantry staples, with the star being your sourdough starter. Don’t worry if your starter isn’t super active; a fed and bubbly starter will yield the best results, but even a slightly less vigorous one will still contribute wonderful flavor and texture.
INGREDIENTS:

- 1 cup active sourdough starter (fed and bubbly)
- 1/2 cup warm milk (about 100-110°F)
- 1/4 cup granulated sugar
- 1 large egg, plus 1 egg yolk
- 1 teaspoon vanilla extract (optional, for extra sweetness)
- 3 cups all-purpose flour, plus more for dusting
- 1 teaspoon salt
- 1/2 cup unsalted butter, softened and cut into small pieces
- 1 large egg, beaten (for egg wash)
- Coarse sea salt or sesame seeds (for topping, optional)
For the milk, whole milk will give you the richest results, but 2% milk works perfectly fine too. If you don’t have vanilla extract, you can omit it; the buns will still be delicious. When it comes to flour, all-purpose is ideal for its balance of protein, yielding a tender crumb. Using good quality unsalted butter will make a noticeable difference in the flavor and richness of your brioche. If you only have salted butter, reduce the added salt in the recipe by about half a teaspoon.
Time Needed From Start To Finish
While these buns do require some patience for the sourdough to work its magic, the active hands-on time is quite manageable.
- Prep Time: 20 minutes (mixing dough, kneading)
- First Rise (Bulk Fermentation): 4-6 hours (or overnight in the fridge)
- Shaping Time: 15 minutes
- Second Rise (Proofing): 1-2 hours
- Bake Time: 20-25 minutes
- Total Time: Approximately 7-9 hours (with active starter, or longer if refrigerating overnight), but only about 1 hour of active work.

Easy Variations And Serving Ideas That Fit Real Life
These sourdough brioche buns are fantastic on their own, but a few simple tweaks and serving suggestions can make them even more special.
- Sweet Toppings: For an extra treat, brush the warm buns with melted butter and sprinkle with cinnamon sugar immediately after baking. A simple glaze made from powdered sugar and a splash of milk or lemon juice also works wonderfully once they’ve cooled slightly.
- Savory Swaps: Omit the vanilla extract and reduce the sugar slightly (to 2 tablespoons) for a more savory bun. You can then mix in some grated Parmesan cheese and a pinch of garlic powder into the dough, or sprinkle fresh herbs like rosemary or thyme on top before baking.
- Kid-Friendly Fun: Let kids help roll the dough into balls. They love the tactile experience! For a fun breakfast treat, you can even press a chocolate chip or a small dollop of jam into the center of each bun before the second rise.
- Party or Buffet Serving: These buns are perfect for a potluck or buffet. Serve them in a basket alongside a variety of spreads like butter, honey butter, or a savory herb butter. They also make excellent sliders for mini sandwiches.
- Sandwich Base: These buns are ideal for breakfast sandwiches with egg and cheese, or for lunch with deli meats, tuna salad, or pulled pork. Their soft texture holds up well to fillings.
Common Slip-Ups And How To Avoid Them
Even experienced bakers can encounter small challenges. Here are some common issues and how to steer clear of them for perfect sourdough brioche buns every time.
- Dough Too Sticky to Handle: Brioche dough is naturally soft and a bit sticky due to its high butter content. Don’t be tempted to add too much extra flour during kneading. A light dusting on your work surface and hands is usually enough. As you knead, the butter will incorporate, and the dough will become more manageable. Using a stand mixer with a dough hook can also save your arms!
- Buns Not Rising: This usually comes down to your sourdough starter not being active enough or the proofing environment being too cold. Ensure your starter is fed and bubbly before you begin. For proofing, find a warm spot in your kitchen (like near a sunny window, or in a slightly warmed-then-turned-off oven). Patience is key; if it’s cold, it will just take longer.
- Over-kneading or Under-kneading: Under-kneaded dough will result in dense, tough buns because the gluten hasn’t developed enough. Over-kneaded dough can also become tough and lose its elasticity. Aim for the “windowpane test” as your guide – when a small piece can be stretched thin enough to see light through without tearing, it’s ready.
