What Is Sourdough Discard?
Sourdough discard is the portion of sourdough starter removed during feeding. Although it may not always be strong enough to rise bread independently, it still contains excellent flavor and natural fermentation benefits.
In donut dough, sourdough discard helps create:
- Tender texture
- Rich flavor
- Slight chewiness
- Better moisture
Using discard also reduces kitchen waste while making delicious recipes.
Ingredients
For the Donut Dough
- 1 cup sourdough discard
- 3 cups all-purpose flour
- 2¼ teaspoons instant yeast
- ½ cup warm milk
- ¼ cup granulated sugar
- 2 large eggs
- ¼ cup unsalted butter, softened
- 1 teaspoon vanilla extract
- ½ teaspoon salt
For Frying
- Vegetable oil or canola oil
For Vanilla Glaze
- 2 cups powdered sugar
- 3–4 tablespoons milk
- 1 teaspoon vanilla extract
For Cinnamon Sugar Coating
- ½ cup granulated sugar
- 1 teaspoon cinnamon
Equipment Needed
- Large mixing bowl
- Rolling pin
- Donut cutter or round cutters
- Heavy-bottomed pot or deep fryer
- Thermometer
- Cooling rack
- Slotted spoon
Step 1: Activate the Yeast
In a large bowl, combine the warm milk, sugar, and instant yeast.
Allow the mixture to sit for about 5–10 minutes until foamy.
This step ensures the yeast is active and ready to help the donuts rise properly.
The milk should feel warm but not hot.
Step 2: Mix the Dough
Add the sourdough discard, eggs, vanilla extract, softened butter, and salt to the yeast mixture.
Stir until combined.
Gradually add the flour, mixing until a soft dough forms.
The dough should feel soft and slightly sticky but still manageable.
Step 3: Knead the Dough
Transfer the dough onto a lightly floured surface.
Knead for about 8–10 minutes until smooth and elastic.
If using a stand mixer, knead with a dough hook for about 5–6 minutes.
Proper kneading develops gluten, giving the donuts their soft chewy texture.
Step 4: First Rise
Place the dough into a lightly greased bowl and cover with plastic wrap or a clean kitchen towel.
Allow it to rise in a warm place for about 1–1½ hours, or until doubled in size.
The dough should become puffy and airy.
The sourdough discard enhances flavor while the yeast provides a reliable rise.
Step 5: Roll Out the Dough
Once risen, punch down the dough gently.
Transfer it to a lightly floured surface and roll it out to about ½-inch thickness.
Avoid rolling too thin because thicker dough creates softer donuts.
Step 6: Cut the Donuts
Use a donut cutter or two round cutters to cut donut shapes.
Place the cut donuts and donut holes onto a parchment-lined tray.
Gather scraps gently and reroll if necessary.
Homemade donuts may not look perfectly uniform, but that adds charm.
Step 7: Second Rise
Cover the donuts lightly and allow them to rise again for about 30–45 minutes.
This second rise helps create light fluffy donuts.
The donuts should look slightly puffed before frying.
Step 8: Heat the Oil
Pour about 2–3 inches of oil into a heavy-bottomed pot.
Heat the oil to 350°F (175°C).
Maintaining the correct oil temperature is important:
- Too hot: donuts brown too quickly outside
- Too cool: donuts absorb excess oil
A thermometer helps ensure consistent frying.
Step 9: Fry the Donuts
Carefully place 2–3 donuts into the hot oil at a time.
Fry for about 1–2 minutes per side until golden brown.
Use a slotted spoon to transfer the donuts to a wire rack lined with paper towels.
Repeat with the remaining donuts and donut holes.
The donuts should feel light, airy, and beautifully golden.
Step 10: Prepare the Glaze
In a medium bowl, whisk together powdered sugar, milk, and vanilla extract until smooth.
Adjust consistency if needed:
- Add more milk for thinner glaze
- Add more powdered sugar for thicker glaze
The glaze should coat the donuts smoothly without being too runny.
Step 11: Glaze or Coat the Donuts
Once the donuts cool slightly:
- Dip them into vanilla glaze
- Or coat them in cinnamon sugar
For cinnamon sugar donuts, brush lightly with melted butter before coating if desired.
Allow glazed donuts to set on a wire rack for a few minutes before serving.
Tips for Perfect Sourdough Donuts
Use Fresh Sourdough Discard
Discard should smell pleasantly tangy, not overly sour or spoiled.
Don’t Overflour the Dough
Soft dough creates lighter fluffier donuts.
Maintain Oil Temperature
Consistent oil temperature prevents greasy donuts.
Don’t Overcrowd the Pot
Too many donuts at once can lower the oil temperature.
Fry Until Golden
Even golden color ensures proper cooking.
Flavor Variations
Chocolate Glazed Donuts
Add cocoa powder to the glaze for rich chocolate flavor.
Lemon Glazed Donuts
Use lemon juice and zest for bright citrus donuts.
Filled Donuts
Fill with jam, custard, or cream after frying.
Maple Donuts
Use maple syrup in the glaze for warm rich flavor.
Coconut Donuts
Sprinkle shredded coconut over glazed donuts.
Why Sourdough Makes Donuts Better
Sourdough discard adds subtle depth of flavor that regular donuts often lack.
The natural acidity also improves texture, making the donuts softer and slightly chewy without becoming dense.
Even people who are not sourdough bakers can enjoy how flavorful and tender these donuts become.
Storage Instructions
Store donuts in an airtight container at room temperature for up to 2 days.
Homemade donuts taste best fresh but can still be enjoyed the next day.
Avoid refrigerating because refrigeration can dry them out.
Freezing Instructions
You can freeze unglazed donuts for up to 2 months.
Allow them to cool completely before freezing.
To serve, thaw at room temperature and warm slightly before glazing.
Serving Suggestions
Sourdough discard donuts pair beautifully with:
- Coffee
- Tea
- Hot chocolate
- Fresh fruit
- Breakfast spreads
- Whipped cream
They are perfect for breakfast tables, dessert platters, brunch gatherings, or holiday mornings.
Common Mistakes to Avoid
Oil Too Hot
This burns the outside before the inside cooks fully.
Oil Too Cool
Cool oil causes greasy donuts.
Overworking the Dough
Too much handling can make donuts tough.
Skipping the Second Rise
The second rise creates airy texture.
Nutritional Notes
Although donuts are definitely a treat, homemade versions allow you to control ingredients more carefully than store-bought donuts.
Using sourdough discard adds flavor without requiring artificial additives or preservatives.
You can also reduce sugar or bake smaller portions if desired.
Make-Ahead Option
The dough can be prepared the night before.
After the first rise, refrigerate overnight.
The next day, allow the dough to come closer to room temperature before shaping and frying.
This method can even improve flavor.
Baked Version Option
If you prefer baked donuts instead of fried:
- Place shaped donuts onto a baking sheet
- Bake at 375°F (190°C) for about 10–12 minutes
The texture will be slightly different but still delicious and softer than cake donuts.
