This sourdough donut recipe produces light yet chewy donuts with an incredible browned butter frosting!
Last fall, when my sisters and I did a food tour of Minneapolis, I had some of the best donuts of my life at Bogart’s Doughnut Co.
They’re famous for their vanilla buttercream filled donuts, but their browned butter flavor actually stole the show for me.
And now I finally got around the recreating them for y’all!
You’re going to die of happiness when you taste them.
Quick note: I switch between spelling it “donut” and “doughnut” in this post.
Leave me a comment letting me know how YOU spell it!
Okay, let’s chat ingredients for a second.
There aren’t a ton of ingredients in this sourdough donut recipe, so it’s important to choose high quality ones!
It’s critical that you use an active sourdough starter. This means that it’s been fed 8-12 hours previously and has doubled in volume and is active and bubbly and passes the float test.
I keep my starter at 100% hydration, which means I feed it equal weights, not volumes, of flour and water.
So for this recipe, place 45 grams of unfed sourdough starter in a jar. Feed it 45 grams each of flour and water. This will give you a little more than the 120 grams of starter you need.
Make sure to read my How to Make a Sourdough Starter From Scratch post if you need any help getting your starter going!
Please use whole milk here, not reduced fat or skim milk!
I use salted grass-fed butter.
Instead of making you soften your butter, I went ahead and used melted. You can go ahead and thank me.
Since we’re making donuts, the dough has more sugar than your typical bread dough.
The final donuts aren’t super sweet since the sourdough tends to counteract that.
But the frosting more than covers the sweet department, no fear.
Of course to bring out the sweet and sour flavors you have to include salt.
I use Redmond Real Salt.
The dough includes one whole egg plus one egg yolk for extra richness.
This lightly perfumes the dough with vanilla, which I think is lovely.
All Purpose Flour:
I highly encourage you to use organic all purpose flour since it doesn’t contain harsh bleaches or pesticides which might not play nicely with your sourdough starter.
How to Make Sourdough Donuts:
Okay, let’s make them!
Mixing the Dough:
Place all of the dough ingredients into the bowl of a stand mixer.
Knead on medium low (a 3 out of 10 on my mixer) for 10 minutes.
Place the kneaded dough into a greased bowl. Cover with a lid and allow to ferment for 8-12 hours, or until it doubles.
If you have a really warm kitchen, the dough might double in as little as 4 hours. But if your kitchen is average to cool, you can get away with letting this rise overnight.
Here’s how much my dough puffed up overnight.
Turn your oven to its lowest setting. Once it’s preheated, turn it off and keep the door shut. This will be your proofing station.
Pat the dough out to about 1/2 inch thick on a piece of parchment paper.
The parchment paper will make your life SO much easier, trust me.
Stamp out circles of dough using a 2¾-inch biscuit cutter.
You can also use a special doughnut cutter, or a mason jar or cup turned upside down.
Use the smallest biscuit cutter in your set to cut out donut holes.
Or you could use a narrow bottle turned upside down.
Of course if you used a specialized donut cutter you can skip this step.
Here’s what they look like all cut out!
Skooch them, parchment paper and all, onto a flat cookie sheet.
Cover with a tea towel.
Place in the warm oven to rise.
I’m lucky enough to have a warming drawer (it came with our Craigslist kitchen), so I let my sourdough doughnuts rise there.
But the oven proofing trick works really well!
Let the sourdough starter donuts rise until they’re quite puffy, about 2-4 hours.
If you let them rise at room temperature, it may take longer than that.
Heat a couple of inches of avocado oil in a 12-inch cast iron skillet.
When the oil reaches about 365°F, carefully drop in a few of the puffy sourdough donuts.
Keep an eye on the temperature of the oil. When you drop in the donuts it will drop several degrees.
Make sure to adjust the flame on the stove so the temperature doesn’t drop below 350° or rise above 375°.
Cook for 1 minute, then flip them over.
You want them to be browned on the bottom, but not super dark.
If your oil is hotter or cooler than 365° you might need to cook them a few seconds more or less.
Cook for another minute on the second side.
Remove to a paper towel lined baking sheet to drain and cool.
Once the regular-sized donuts are done frying, it’s time to fry the sourdough donut holes!
Carefully drop several into the hot oil.
Fry for 1 minute on each side.
Sometimes a few of them will refuse to flip over.
That’s okay – they’ll still get cooked. They just won’t look as pretty.
I mean, these are delicious as-is.
But to take them to the next level, you have GOT to make my browned butter frosting!
Making the Browned Butter Frosting:
While the donuts are cooling, start making the browned butter frosting.
Brown 2 tablespoons of butter.
This is where the magic is.
You can check out my How to Brown Butter tutorial if you’ve never done it before!
Sift 3/4 cup powdered sugar into a medium bowl.
Holy moly, my powdered sugar was lumpy!
Add the browned butter, 2 tablespoons of cream, 1/4 teaspoon pure vanilla extract, and a pinch of salt to the bowl.
Whisk until smooth.
You may need to add more cream in order get the proper consistency.
You don’t want it super thin, or crazy thick. Just nice and medium.
There are a couple of options for how to get the frosting onto these sourdough doughnuts.
First, you could use a knife or offset spatula to spread in onto the cooled donuts.
Or you could pour it on top.
Finally, you could dunk them.
Experiment and see which method works best for you!
I mean…how could you say no to that?!
Here’s a video tutorial in case you learn better that way:

I’d love to experiment with different toppings!
Here are a few flavor ideas I had:
- Chocolate with sprinkles
- Maple pecan
I’d also like to experiment with filled donuts!
Ugh…a Boston Cream Pie inspired doughnut would be SO good!
All right, I’d better leave you with the recipe before I get too carried away. 🙃

Sourdough Donut Recipe
These sourdough donuts use a risen dough and are topped with an amazing browned butter frosting!
For the Donuts:
- 1/2 cup whole milk (122 grams)
- 1/2 cup active sourdough starter (120 grams) - see note
- 1/4 cup butter, melted and cooled
- 1/3 cup can sugar (72 grams)
- 1/2 tsp unrefined sea salt
- 1 whole egg
- 1 egg yolk
- 2 tsp pure vanilla extract
- 2 1/4 cups organic all-purpose flour (330 grams)
- avocado oil, for frying
For the Frosting:
- 2 tbsp butter, browned (see note)
- 3/4 cup powdered sugar, sifted
- 2 tbsp heavy cream, plus extra to achieve correct consistency
- 1/4 tsp pure vanilla extract
- 1 pinch unrefined sea salt
For the Donuts:
Place all of the ingredients for the dough in the bowl of a stand mixer.
Using the dough hook, knead for 10 minutes on medium-low (3 out of 10 on my mixer).
Transfer the dough to a greased large bowl. Cover and allow to ferment at room temperature until doubled, about 8-12 hours, depending on how warm your kitchen is.
Turn your oven on to its lowest setting, and once it's preheated, turn it off and leave the door closed.
Place the dough on a large piece of parchment paper. Using your hands (grease if necessary) pat the dough out into a rectangle until it's about ½ inch thick.
Using a biscuit cutter, mason jar, glass, or donut cutter, stamp out rounds of dough. Using the smallest biscuit cutter in your set or a small bottle, stamp out donut holes.
Arrange the donuts and holes on the parchment paper about and inch apart and transfer them, parchment paper and all, onto a flat baking sheet. Place in the warm oven and allow to raise until quite puffy, about 2-4 hours.
Line a rimmed baking sheet with paper towels.
Heat a couple of inches of avocado oil in a 12 inch cast iron skillet to 365°F - 375°F. Drop 4-5 of the doughnuts carefully into the hot oil. Cook for 1 minute on each side. You don't want them to be super pale or really dark. A nice golden brown is perfect.
Keep and eye on the temperature and make sure the oil doesn't drop below 350°F or rise above 375°F.
Remove the cooked doughnuts to the paper towel lined baking sheet.
Repeat the cooking process with the remaining donuts, then the donut holes. Some of the holes may refuse to flip over - that's okay!
Allow the donuts to cool until just barely warm before frosting.
For the Frosting:
Place the powdered sugar, browned butter, cream, vanilla, and salt in a medium bowl. Whisk until smooth. Add more cream to achieve a consistency that's between a spreading and pouring consistency.
You can either spread the frosting on the donuts with an offset spatula, pour the glaze on top of them, or dunk them. I personally find that dunking is the least effective.
These donuts are best served immediately, but you can store them in an airtight container in the fridge if needed. Best if reheated, of course!
- An active starter is one that's been fed 8-12 hours previously, has doubled and is bubbly and passes the float test.
