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.
A full ingredient list with exact amounts can be found in the recipe card below.
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.

This was my first attempt at sourdough donuts and I am totally hooked! So good!
Sourdough has a special place in my heart!
I’m always amazing at the things you do with sourdough and every time it’s something I have never thought of.
I am looking into the purchase of the NutriMill Classic 760200 High Speed Grain Mill. Which wheat berries do you use? Hard white, soft white, or hard red spring wheat berries?
Also, I just found a local farm here in Texas that sells raw milk. I am hooked! Delicious!
Thanks ever so much Lisa!
God bless,
Julie
These were amazing, they were so soft and perfect!
Did you use bread flour for this? Or all purpose?
Hey there! I have been thoroughly enjoying your sourdough recipes!! I use a Nutrimill for my grains as well. I recently heard that the heat created in the milling process may damage the grain or have negative health benefits. Have you heard anything about this? Just curious as I haven’t had a moment to research it for myself!
How do I start the sourdough starter from scratch?
I have a post all about it here: https://www.farmhouseonboone.com/farmhouse-on-boone/make-sourdough-starter-scratch/
Lisa,
I recently discovered your blog and have enjoyed reading your posts, especially regarding your sourdough recipes. My family has several members who have been diagnosed as living with food allergies, one of which is wheat (not gluten, but the grain itself.) Our doctor pointed out that the fermentation of sourdough often “processes” the wheat in a way that makes it digestible for many with wheat intolerance. There is sourdough developing in my kitchen as I write this. I like your recipes because they ferment over night giving the bacteria time to break down the wheat. Do you make loaf bread with a long fermentation too? If so, will you be sharing that recipe soon? Thank you, Jen
Good morning! I am making these donuts this morning and while they rise I wanted to ask if you have any advice for cutting them out. Is there a strategy? I used a circle cutter and a small cup for the middle but lifting it up made a mess despite the floured work surface. I eventually switched to donut sticks, and then small squares rolled into donut holes using my bench scraper. ? Thanks in advance! I love your posts!
Make sure what you are using to cut them is sharp/thin enough to cut. The donut sticks sound great though! 🙂
Is your dough on the sticky side? It stretched a lot when I tried to pick them up and transfer them to the pan. Square donut hole sized bites ended up working best for getting into the pan, flipped and back out of the pan. 😉
How does the water taste?
This recipe looks sooo good! I was wondering if you had any suggestions for substituting the milk and butter? I can’t have diary and haven’t had a donut in forever! Would love to make these donuts this weekend for my family!
I would try a dairy free milk and maybe coconut oil or a plant based butter would work. Good luck! Hope you love them.
Looks yummy…can you use Amish friendship bread starter?
I have heard of the amish friendship bread starter but I don’t know a whole lot about it. Doesn’t it use milk? People do pass it around and keep it going for years, right?
Which Berkey water filtration system do you have. How often do you have to change the filters with your size of family. How many gallons of water to you probably go through a day. How long have you had yours . Do you think there worth the money.
Thank you so much I’m interested in your input .
Sincerely
Terry Dewhurst
I have this one: http://amzn.to/2CIgcS7 We have a family of seven. I have no idea how many gallons per day, but we all drink exclusively from it. The filters last a really long time, if you don’t break them. We have had ours seven years, and replaced them twice. Both times only because a kid knocked it over and broke one. Even if there is a hairline crack they won’t filter properly. You can test them to see if they are still working. You put food coloring in the top basin and put each filter over a clear glass. They should filter out all the color. We love our Berkey!
