Same-Day Sourdough Donuts
sourdough donuts without the wait
Homemade donuts have a reputation that keeps most people from trying them. Hot oil, a thermometer, and dough that needs to be handled just right. The whole thing sounds like a project with a high margin for error and a kitchen that smells like a fryer for the rest of the day.
Here is what actually happens when you make this recipe. The dough comes together in a stand mixer. It rises on the counter while you do other things. The frying takes less than five minutes per batch. And what comes out is a donut that is light and pillowy and just slightly tangy from the starter, dipped in a vanilla glaze that sets into a thin, crackly shell as it cools. The kind of donut that makes the effort feel like an obvious trade.
The sourdough starter is not here to make this complicated. It is here to make the donut taste like something more than just fried dough, which it does very quietly and very effectively.
Why Both Starter and Yeast
Using an active sourdough starter alongside a small amount of commercial yeast is a decision worth explaining because it looks unusual at first glance. The yeast is there for reliability and speed. Two grams is a small amount, just enough to guarantee a predictable rise within the same-day timeline without taking over the flavor of the dough entirely. The starter is there for everything the yeast cannot provide: complexity, a faint tang, and the particular chew that fermented dough has and straight yeasted dough does not.
Together, they produce a dough that rises confidently within six hours, but it still has some of the benefits of fermented dough. Neither ingredient on its own gets you to the same place.
Refined Oil Is Not a Suggestion
The frying oil specification matters more than it might seem. Refined coconut oil has a neutral flavor and a high smoke point that makes it exceptionally well-suited to frying at 350°F. Unrefined coconut oil has a distinct coconut flavor that will transfer directly to the donuts, which is not what anyone is after here. Vegetable or canola oil works in a pinch, but refined coconut oil produces a cleaner fry with a slightly crisper exterior that holds up better under the glaze.
Three inches of oil depth in a Dutch oven gives the donuts enough room to float freely and cook evenly on both sides without touching the bottom of the pan. A thermometer is non-negotiable. Oil that is too cool produces greasy, dense donuts that absorb fat instead of crisping. Oil that is too hot browns the outside before the interior has a chance to cook through. 350°F is the number, and it’s worth waiting for.
Two Minutes Per Side and Not a Second Longer
The fry time is short because it has to be. These donuts are light and airy and fully proofed, which means the heat moves through them quickly. Two minutes per side until the exterior is an even, deep golden brown is the window. Pull them too early and the inside is doughy. Leave them too long and the outside gets away from you before you realize it.
A slotted tray or a wire rack over a sheet pan lets the excess oil drain without the donuts sitting in it and softening the crust you just built. They need about sixty seconds of draining before the glaze, which is just enough time to set up the next batch in the oil.
The Glaze Sets, and That’s the Point
Dipping both sides of a warm donut into the glaze while it is still hot from the oil is the move that makes the coating work the way it should. The heat from the donut thins the glaze on contact and allows it to adhere evenly across the entire surface. As the donut cools, the glaze firms from liquid to set, going from glossy and wet to a thin, slightly crackly shell that shatters faintly when you bite through it.
If the glaze sits too long before the donuts go in, it will thicken and apply unevenly. Whisk it just before dipping and keep it at room temperature throughout. The salt and vanilla in the glaze are there to keep it from tasting purely sweet, giving it just enough dimension to complement the tang of the dough underneath rather than covering it up entirely.

Ingredients
FOR THE DOUGH:
- 500 g All Purpose Flour
- 100 g Sourdough Starter (active)
- 2 g Active Dry Yeast
- 170 g Warm Milk
- 80 g Granulated Sugar
- 57 g Butter (room temp)
- 3 Eggs
- 6 g Salt
- 10 g Vanilla Extract
FOR THE GLAZE:
- 200 g Milk
- 500 g Powdered Sugar
- 5 g Salt
- 10 g Vanilla Extract
FOR FRYING:
- Refined Coconut Oil (MUST be refined, enough for 3" depth in your frying vessel)
Instructions
- Add the milk, sugar, and yeast to the bowl of a stand mixer. Allow the yeast to bloom for 5 minutes. Then, add the flour, starter, eggs, salt, and vanilla. Mix on low with the dough hook attachment for 5 minutes.
- Then, increase the mixer speed to medium and add the butter 1 tbsp at a time. Allow the dough to mix for 10-15 minutes, until the dough begins pulling away from the sides of the bowl and it passes the window pane test.
- When the dough is done mixing, form it into a uniform ball, cover the bowl, and allow it to rise until fully doubled. In a 72°F home, this should take around 6 hours.
- Once the dough is perfectly proofed, add the refined coconut oil to a dutch oven or other frying vessel. Once melted, you want 2-3” of oil in the pan. Allow it to heat up to 350°F.
- While the oil is heating, punch down the dough and roll it out onto a floured surface until it is around 1/2” thick. Use a donut cutter to begin cutting donut shapes. Take the excess dough and knead it back into a ball. Allow the extra dough to rest, and then you can re-roll it to cut out more donuts.
- Prepare your donut icing by whisking together the milk, powdered sugar, salt, and vanilla until smooth. Set aside.
- Once the oil hits 350°F, fry the donuts for around 2 minutes on each side, just until they reach a beautiful golden brown color. Remove the fried donuts and place them on a slotted tray to allow any excess oil to drip.
- While the donuts are still warm, dip both sides into the glaze. As the donuts cool the glaze will harden.
