Sourdough donuts are a delightful fusion of traditional donut flavors with the tangy essence of sourdough. They’re soft, slightly chewy on the outside, and supremely fluffy inside. Imagine biting into a warm, cloud-like donut that seems to melt in your mouth, with a hint of nuttiness and a perfect balance of sweetness. The process of making these donuts also pairs wonderfully with both inexperienced and seasoned home bakers.
Delving into sourdough can feel like a journey—one that rewards you with rich flavors and satisfying textures. Whether you’re planning to impress friends or seeking a weekend project, these donuts are a perfect fit for busy parents or anyone cooking on a budget.
What Is Sourdough Donut?
A sourdough donut is more than just a donut; it’s a culinary experience that combines the baking techniques of traditional donuts with the unique fermentation process of sourdough bread. By incorporating a sourdough starter, these donuts not only gain a distinct tanginess but also a lovely depth of flavor that traditional yeast donuts lack. The fermentation process allows for complex flavors to develop, making each donut a treat for the senses.
In terms of texture, sourdough donuts are airy and tender, resulting in a delightful mouthfeel. They are typically fried to golden brown perfection, creating a crispy exterior that complements the soft interior. You can enjoy them coated in sugar or glaze, or even stuffed with jam or cream for an added surprise.

Ingredients You’ll Need
For these delicious sourdough donuts, gather the following ingredients:
- 2 cups active sourdough starter: A well-fed and bubbly starter is crucial; this will create the fluffy texture and tangy flavor.
- 1/2 cup milk: This helps hydrate the dough, ensuring softness and moisture.
- 1/4 cup sugar: Sweetens the donuts, balancing the slight sourness from the dough.
- 1 large egg: Adds richness and helps bind the ingredients together.
- 1/2 teaspoon salt: Enhances flavor and controls yeast activity for the right rise.
- 4 cups all-purpose flour: The base of the dough; provides structure while remaining light and fluffy.
- 1 teaspoon nutmeg: Optional, but it adds a warm, aromatic spice that complements the sweetness.
- Oil for frying: Any neutral oil is best for frying—you want oil that reaches a high temperature without smoking.
- Powdered sugar for dusting: Provides a classic finish and an added touch of sweetness.

How to Make
Follow these steps to create mouthwatering sourdough donuts:
- Prepare the Dough: In a large bowl, combine the active sourdough starter, milk, sugar, egg, and salt. Mix until smooth. The starter should be bubbly and lively, which will contribute to the rise of the donuts.
- Add Flour: Gradually add the flour, stirring until a soft dough forms. If you are adding nutmeg, incorporate it now. The dough should be sticky but manageable; you can use a little extra flour on your hands if it gets too tacky.
- Knead the Dough: Turn the dough out onto a lightly floured surface and knead for about 5 minutes until smooth and elastic. This step develops the gluten, which is essential for the donut’s texture.
- Let It Rise: Place the dough in a greased bowl, cover it with a damp cloth, and let it rise in a warm place for 1-2 hours, or until doubled in size. Patience is key here; allow the sourdough to work its magic!
- Shape the Donuts: Once risen, punch down the dough and roll it out on a floured surface to about 1-inch thickness. Use a donut cutter to cut out your donuts and donut holes. Place them onto a parchment-lined baking sheet.
- Heat the Oil: In a deep skillet or fryer, heat oil to 350°F (175°C). Use a thermometer to measure the temperature, as too hot oil can burn the donuts while too cool will make them greasy.
- Fry the Donuts: Fry a few donuts at a time, about 1-2 minutes on each side until golden brown. Be cautious not to overcrowd the pan; this prevents the oil temperature from dropping too much.
- Drain and Dust: Remove donuts from the oil and let them drain on paper towels. While they’re still warm, dust them with powdered sugar for a sticky, sweet coating.
Variations & Substitutions
Glazed Sourdough Donuts: For a sweeter donut, prepare a simple glaze using powdered sugar and milk. Mix 1 cup of powdered sugar with 2-3 tablespoons of milk and a splash of vanilla extract until smooth. Dip warm donuts in the glaze and allow to set.
Chocolate Sourdough Donuts: To make chocolate donuts, add 1/2 cup of unsweetened cocoa powder to the flour mixture. You can also chocolate glaze these by melting chocolate with a bit of heavy cream for a decadent finish.
Cinnamon Sugar Sourdough Donuts: After frying, toss the warm donuts in a mixture of cinnamon and sugar (1/2 cup sugar with 2 tablespoons of cinnamon) instead of powdered sugar. The warm donuts soak up the mix, creating a crispy, flavorful exterior.
Fruit-Filled Sourdough Donuts: To make filled donuts, use a piping bag to inject your favorite jam or cream into the center of the fried donuts. Raspberry jam or vanilla pastry cream works beautifully!
Vegan Sourdough Donuts: Replace the egg with a flax egg (1 tablespoon ground flaxseed + 2.5 tablespoons water, let sit for 10 minutes). Use a non-dairy milk such as almond or soy milk to replace regular milk.
Common Mistakes to Avoid
One common mistake people make is using inactive sourdough starter. Always ensure your starter is well-fed and bubbly. This is vital for the donut’s lift and flavor.
Another issue is frying at the wrong temperature. Too cool oil will absorb into the donuts, making them greasy, while oil that’s too hot will burn the outside before the inside is cooked. Use a thermometer for best results.
Not giving your donuts enough time to rise can lead to dense centers. Be patient with the rise time, as this step is crucial for airy, fluffy donuts.
Finally, be mindful of your dough’s consistency; it should be slightly tacky but manageable. Adding too much flour during the kneading process can lead to tough donuts.
Storage, Freezing & Reheating Tips
To keep your sourdough donuts fresh, store any uneaten donuts in an airtight container at room temperature for up to 2 days. If you wish to prolong their shelf life, consider freezing them. Wrap each donut individually in plastic wrap and then place them in a freezer-safe bag. They can last in the freezer for up to 3 months.
To reheat, simply thaw at room temperature, and then warm in the oven at 350°F (175°C) for about 5 minutes. This will help regain their fresh-out-of-the-oil texture and warmth.
When reheating filled donuts, ensure you’re consistent with timing to prevent any filling from becoming too hot or too runny.
Frequently Asked Questions
Can I use my sourdough discard for this recipe? Yes, you can incorporate sourdough discard in this recipe as long as it’s in a decent state. However, you may need to adjust the liquid ingredients slightly, as discard can vary in consistency.
How do I know if my donuts are done frying? Donuts should turn a beautiful golden brown color and will puff up as they cook. You can also insert a toothpick into one; if it comes out clean, the donut is done.
Can I bake these donuts instead of frying them? Yes, you can bake them! Preheat your oven to 375°F (190°C) and place the shaped donuts on a lined baking sheet. Bake for about 12-15 minutes until they are cooked through. Note that baked donuts will have a different texture compared to fried ones.
What if my dough is too sticky? If your dough feels too sticky, add a little more flour, one tablespoon at a time, until it reaches a manageable consistency. However, be careful not to add too much, as this can alter the final texture.
Can I make these donuts ahead of time? Yes, you can prepare the dough a day in advance and let it rise in the refrigerator overnight. When you’re ready to fry, just lightly punch down the dough and allow it to come to room temperature before shaping and frying.
Conclusion: Sourdough donuts are not just a treat, but an enjoyable project that brings the fun and cozy spirit of baking into your kitchen. The tangy flavor from the sourdough paired with warm spices and sweet glazes makes these donuts irresistible. Involve your family in the process and celebrate the art of baking together.
