If you’ve never had a sourdough donut, prepare for a delightful twist on your classic treat. These golden, fluffy rings have a signature tang that sets them apart, thanks to the slow fermentation of the sourdough starter. The result? A donut with incredible depth of flavor, slightly chewy texture, and a rich, buttery finish.

What makes these extra special is that they’re not just dessert; they’re a labor of love that turns any morning into a mini celebration. Sourdough donuts are perfect for lazy weekend brunches, indulgent breakfasts, or a cozy afternoon snack. Whether you top them with a classic vanilla glaze, dust them in cinnamon sugar, or go bold with a maple drizzle, each bite carries the comfort of homemade goodness.

What Kind of Sourdough Starter Should I Use?

You’ll want a mature, active sourdough starter that’s been recently fed and is bubbling with life. Ideally, use a 100% hydration starter (equal parts flour and water) for the most consistent dough results. If your starter is more tangy or mellow, that character will carry into the final flavor of your donuts—so feel free to tailor it to your taste.

Ingredients for the Sourdough Donut

Sourdough Starter
This is the heart of the donut—it brings both leavening and that subtle, tangy depth that makes these unique.

All-Purpose Flour
Gives the donut its tender structure while keeping the texture light and airy.

Whole Milk
Adds moisture and richness to the dough, helping it fry to golden perfection.

Granulated Sugar
Sweetens the dough just enough and also helps feed the starter during fermentation.

Eggs
Bind the dough and add fat for a soft, enriched texture.

Butter
Melted into the dough, butter gives these donuts their indulgent, bakery-quality flavor.

Salt
Balances the sweetness and enhances the flavor of every ingredient.

Vanilla Extract
Adds warmth and depth—especially delicious if you opt for a glaze.

Vegetable Oil (for frying)
Neutral oil is best for deep frying, creating that golden, crisp exterior.

Optional Glaze or Toppings
Try classic vanilla, maple, or even a dusting of cinnamon sugar—customize them your way!

How To Make the Sourdough Donut

Step 1: Mix the Dough

In a large bowl, combine your active sourdough starter, warm whole milk, sugar, eggs, melted butter, and vanilla extract. Whisk until fully blended. Then, add the all-purpose flour and salt. Stir until the dough comes together, then knead until smooth and elastic—about 8 to 10 minutes by hand or 5 to 6 minutes in a stand mixer.

Step 2: Bulk Fermentation

Transfer the dough to a lightly greased bowl, cover with a damp towel or plastic wrap, and let it rise at room temperature for 4 to 6 hours. You want it to double in size. For an overnight option, place the covered bowl in the refrigerator for 8 to 12 hours. This long fermentation enhances flavor and texture.

Step 3: Roll and Cut the Donuts

Once the dough has risen, gently deflate it and turn it out onto a floured surface. Roll the dough to about 1/2 inch thickness. Use a donut cutter (or two different-sized round cutters) to shape your donuts. Don’t forget to save the donut holes!

Step 4: Final Proof

Place your cut donuts on parchment paper-lined trays. Cover loosely and let them rise again for about 1 to 2 hours, until they look puffy and slightly airy when gently touched.

Step 5: Fry to Golden Perfection

Heat vegetable oil in a deep fryer or heavy pot to 350°F (175°C). Carefully add 2 to 3 donuts at a time, frying each side for about 1 to 1½ minutes until golden brown. Use a slotted spoon to remove them and place on paper towels to drain.

Step 6: Glaze and Enjoy

While still warm, dip the donuts in your glaze of choice or toss them in cinnamon sugar. Let them set for a few minutes before serving. These are best enjoyed fresh but are still soft and delicious the next day too!

How to Serve and Store Sourdough Donuts

Sourdough donuts are absolutely irresistible when served warm, just minutes after glazing or sugaring. Pair them with a hot coffee or chai latte for the perfect morning indulgence. You can also get creative by topping them with seasonal glazes like apple cider or pumpkin spice for a festive twist.

To store, let the donuts cool completely and keep them in an airtight container at room temperature for up to 2 days. For longer storage, freeze unglazed donuts in a zip-top freezer bag for up to 2 months. Simply warm them in the oven and glaze fresh before serving.

Frequently Asked Questions

Can I use discard sourdough starter?

You can, but for best rise and flavor, an active starter is preferred. Discard won’t have the same leavening power.

How long should I ferment the dough?

A 4 to 6 hour room temp rise or an 8 to 12 hour overnight cold ferment works best. Longer ferments mean deeper flavor!

Can I bake these instead of frying?

Yes, though they won’t have the same crispy exterior. Bake at 375°F for 10 to 12 minutes and brush with melted butter after.

What oil is best for frying donuts?

Use a neutral oil with a high smoke point like vegetable, canola, or peanut oil. Avoid olive oil.

Why are my donuts oily or dense?

The oil may have been too cold, or the donuts under-proofed. Make sure oil stays at 350°F and the dough is puffy before frying.

Can I glaze them ahead of time?

Yes, but they’re best glazed shortly before serving. Glazing too early can make them soggy if stored.
