Fermented overnight for the softest, fluffiest texture, these irresistible sourdough donuts are fried in coconut oil until perfectly crispy and dipped in a sweet, vanilla glaze.
Homemade donuts win breakfast every time. Growing up, these delightful treats were generally saved for special occasions. They always left our fingers covered in powdered sugar and wishing there were just a few more. Perhaps we all savor our memories of homemade donuts, whether cut out of canned biscuits or made from scratch.
This recipe introduces sourdough fermentation for the best sourdough donuts. If you didn’t think donuts got better, prepare for a new favorite recipe.
Fermenting the donut dough results in a tender, airy crumb, as well as a rich sourdough tanginess. Frying them in a cast-iron skillet until golden brown enriches that flavor even more, and dipping in glaze or dusting with powdered sugar takes them over the top.
While donuts never claimed to be healthy, we might argue that these sourdough donuts come as close as possible. With fermented grains, healthy fats, and zero additives, I don’t feel bad at all about feeding these pillowy little treats to my family.
As you can see, sourdough isn’t only for bread recipes. From these sourdough donuts to sourdough croissants, an easy lemon sourdough cake, and even sourdough peanut butter cookies, we love working sourdough into our favorite things. If this piques your interest, head to my blog to learn how to make your own sourdough starter, how to use sourdough starter, and how to keep it going for years to come.
Why You’ll Love This Recipe
Flavorful and delicious – The rich ingredients and slight sourdough tang work harmoniously to create the best donuts – lightly sweetened, lightly tangy, and absolutely nostalgic.
Pillowy and crisp – Fried until golden brown, these donuts develop a mouthwateringly crisp exterior that, once broken into, reveals a light, fluffy crumb.
Simple and fully fermented – Only simple ingredients in this recipe. The batter is fermented for up to 24 hours for a more digestible and nutritious treat.
Ingredients
Milk – Preferably whole milk, as it achieves a better texture for the donuts and a good consistency for the glaze.
Sugar – Organic, unrefined.
Flour – I like to use all-purpose flour for this recipe. You could also use freshly milled whole grain, though the texture will be a little different and not as fluffy.
Sourdough starter – This should be a fed and active sourdough starter that is nice and bubbly.
Oil – For frying donuts, I suggest tallow, lard, avocado oil, or coconut oil. These are healthy, unrefined oils with higher smoke points.

How to Make Sourdough Donuts
Step 1: Feed your sourdough starter 4-12 hours before starting the dough. Warm the milk, sugar, and butter in a saucepan over low heat, whisking to dissolve the sugar.
Step 2: Add the melted butter mixture to the bowl of a stand mixer with a dough hook attachment. Add two cups of flour to the mixer bowl and combine on low. I like to do this to make sure the milk mixture has cooled down enough before adding my starter.
Step 3: Add starter, eggs, the remaining flour, and salt. Knead on low until smooth and elastic. This took about 10 minutes for my dough to finally come together and pull away from the sides of the bowl.
Step 4: Cover the dough with plastic wrap or beeswax wrap and leave it in a warm place to rise for 5-6 hours. After rising, place the dough in the fridge overnight.
Step 5: The next day, take the risen dough out of the fridge and roll the dough out on a lightly floured surface with a rolling pin to 1/4-inch to 1/2-inch thickness. Only use as much flour as necessary. Too much flour can cause the donuts to become dense and bready.
Step 6: Cut the donuts out. I usually use a cup or a large biscuit cutter and a smaller bottle-type cap to cut the center, since we don’t have a donut cutter.
Step 7: Place the cut donuts on a baking sheet and cover with a damp tea towel or plastic wrap. Let them rise for 1½ to 2 hours at room temperature. A warmer or cooler location will determine how long the rise takes.
Step 8: Add about 1/2 inch of frying oil to a cast-iron skillet. Heat the oil over medium heat until it sizzles when something is added.
Step 9: Fry each donut for 2 to 3 minutes, then flip them and fry another 2 to 3 minutes on the other side until puffy and golden. Be careful not to overcrowd the pan. Place the donuts on a wire rack over parchment paper to cool for a bit before glazing.
Step 10: Add butter, milk, vanilla, and powdered sugar to a small saucepan over low heat. Stir occasionally until fully melted and combined. Dip each donut in the glaze and return to the cooling rack to set. Serve fresh!
Tips
- If you are sensitive to wheat, try fermenting the dough for up to 24 hours. This can really help make those grains easier to digest.
- Placing the dough in the refrigerator overnight is essential. This helps develop the flavors while slowing down the fermentation process so it doesn’t over-ferment.
- When deep frying, test one in the hot oil before frying the whole batch. The temperature may need adjustment.
- You don’t need fancy equipment to cut out the donuts. I usually just find whatever objects we have on hand. A wide-mouth mason jar and a bottle cap for the holes will work perfectly fine.
- For this recipe, I dunked the donuts in a simple glaze, but you could also top them with powdered sugar or a cinnamon sugar topping.
- Want to add some fun flavors to the glaze? Add a spoonful of your favorite jam to give it a fruity flavor.
- Fry up the donut holes, as well!
Recipe FAQs
The longer the grains ferment with the active sourdough starter, the more easily digestible they become. People sensitive to wheat or gluten often tolerate sourdough products better when the grain has been fermented for 24 hours. The flavor also deepens during fermentation, resulting in a tangy, sour taste that complements the deep-fried coconut oil flavor and sweet glaze.
If somehow you have a few leftovers, you can store them in an airtight container (or bag), or wrap them in a napkin and place them in a paper bag – fold over the top. I like to add a napkin to help absorb any extra oil and keep them fresh longer.
I like to pop them in the oven for a few minutes to warm them up without drying them out.
In this case, yes. This recipe uses simple ingredients, employs the benefits of sourdough fermentation, and contains zero additives or preservatives.
These donuts can be fermented for 8-24 hours, so how long they take depends on your schedule and preferences. With prep time running around 15 minutes, you could start the shaping and frying anywhere from 8 to 24 hours after assembling the ingredients.

Can you freeze the donuts?
I haven’t tried freezing these yet, so I can’t say for sure. I would say the final product should be able to be frozen. But potentially you could freeze them after cutting and then let them thaw at room temperature for 10-12 hours or so to rise before frying. I’m basing this off of freezing something like cinnamon rolls.
Oh my goodness this one is a keeper! I’m never going back to store bought doughnuts. How many doughnuts did you get out of this? I got a little more than 16 and I even baked some of the holes I cut out. I also baked them in the oven instead and they turned out great. I’ve really been enjoying using my starter with your recipes!
hey there, how long/ what temp did you bake these?
Can you cut these out then freeze the dough? I’m planning to make these for a camp out and thought I could speed up the process by having them ready to fry, but didn’t know if they would raise properly?
Oh that is a great question. I’ve never tried it so I can’t say for sure this would work. But potentially you could freeze them after cutting and then let them thaw at room temperature for 10-12 hours or so to rise before frying. I’m basing this off of freezing something like cinnamon rolls.
I used the baking instructions from the prairie homestead. She has a recipe on doughnuts. But I do like this sweet dough recipe, just made another batch today. I think I’m going to fry them in coconut oil this time. Sorry for the extremely late response.
These were amazing! All of your recipes are gold! Thank you for making sd easy to understand.🥰
So glad you enjoyed it and thank you for the kind words!
How long can the dough stay in the fridge? I mixed mine up
And got them in the fridge last night, and this morning my family woke up with the stomach virus, so probably not feeling like eating donuts today.
Oh no I hope you feel better. I would think they would be fine in the fridge for a few days.
I had the same question about leaving it in the fridge for a full day. I won’t be home today so I’ll be able to deal with it sometime tomorrow. My other question is if I can freeze the other half of the fermented dough? I ended up having to add more flour to it than the recipe called for so my dough will be a little larger.
Does the starter need to be fed and bubbly for this recipe ? Sour dough newbie here 🙋🏼♀️
Yes! You should use fed and active sourdough starter that is nice and bubbly.
This recipe is different than the recipe book. I made both, they are very similar but I liked this one better. I did add another cup of flour to the dough because it was to thin. I bake them in the air fryer for 7 minutes flipping half way. I also dipped them in oil before baking. They double in size when baking. Definitely a new favorite.
I’m fairly new to sourdough and absolutely love all your videos! I’ve tried a bunch of your recipes so far and the reoccurring problem I always have is the dough is way too wet and sticky and never comes todgether fully. I’ve tried kneading longer and adding flour, I am currently on about 30 mins of the kitchen aid running trying to get the dough to come together at all, and I’ve added at this point about an extra full cup of flour. I feel like I have to experiment with the recipes so much to make the dough come together I ruin them! Any advice is appreciated!
Sometimes it really does feel like that. I’m sorry you are having issues with some recipes. Depending on the humidity of where you live, the hydration of your starter, and the flour you use all can be determining factors. Sometimes you may need to add a little more flour, especially if you have been kneading for 30 minutes and it’s not working.
Adding to my previous comment.
They are delicious!
My husband and I LOVE them!
These were surprisingly easy to make. I didn’t glaze mine just sprinkled with cinnamon and sugar mixture.
Question: How well do they freeze?
Thanks.
I’m crying these are so delicious. My daughters have recently realized they are gluten sensitive and they’ve been devastated realizing they get tummy aches eating their favorite treats. Not anymore! These were perfection and tummy ache free. Thank you so much!!
So glad you all were able to enjoy them!
