Sourdough Donut Ingredients

• Here’s what you need to create the most delightful Sourdough Donuts:

For the Donut Dough

Whole Milk – Provides moisture; warm it to 110-120°F to activate the yeast without killing it.
Granulated Sugar – Sweetens the donuts and aids in yeast activation.
Active Dry Yeast – Leavens the donuts for a light, airy texture.
Sourdough Discard – Adds a unique tangy flavor; use a heaping amount (about 6 oz).
Salted Butter – Enriches the dough for added flavor; make sure it’s softened or melted and cooled.
Eggs (Large) – Contributes richness and acts as a binder; use them at room temperature for better mixing.
Ground Nutmeg – Infuses aromatic flavor that enhances the overall taste.
All-Purpose Flour – Provides structure; ensure to have extra for dusting when rolling out.

For Frying

Vegetable or Canola Oil – Essential for frying; heat to 375°F for optimal results.

For the Glaze

Powdered Sugar – The star ingredient for your glaze, providing sweetness and texture.
Pinch of Salt (for glaze) – Balances the sweetness for the perfect finishing touch.
Additional Milk – Mix with powdered sugar to achieve your desired glaze consistency.

Step‑by‑Step Instructions for Sourdough Donuts

Step 1: Mix Yeast Mixture
In your stand mixer, combine 1 cup of warm whole milk (110-120°F) and 2 tablespoons of granulated sugar. Sprinkle 2 teaspoons of active dry yeast over the surface and let it foam for 5-10 minutes. You’ll know it’s ready when the mixture appears bubbly and frothy, indicating the yeast is activated.

Step 2: Combine Ingredients
Once the yeast mixture is bubbly, add 6 oz of sourdough discard, 2 large eggs (at room temperature), and 4 tablespoons of softened salted butter. Include ½ teaspoon of ground nutmeg for that warm flavor. Mix on low speed until everything is well incorporated, creating a creamy dough base.

Step 3: Incorporate Flour
Gradually add approximately 3-4 cups of all-purpose flour to the dough while mixing at low speed. Continue until the dough pulls away from the bowl’s sides and forms a soft, slightly sticky ball. Aim for a consistency that’s smooth yet pliable, which should take about 5 minutes.

Step 4: Rest Dough
Transfer the dough to a greased bowl, covering it with plastic wrap. Refrigerate for about 1 hour, or until the dough has doubled in size. This resting period helps develop the flavors of your Sourdough Donuts, making them wonderfully fluffy.

Step 5: Roll Out
After the dough has risen, transfer it to a floured surface. Roll the dough out to a thickness of ½ inch, ensuring it’s evenly rolled to achieve consistent donuts. Use a donut cutter to cut out shapes, and remember to save the scraps for re-rolling later.

Step 6: Second Rise
Place the cut donuts onto a parchment-lined sheet, giving them space to rise. Cover lightly and let them rest for about 1 hour, or until they appear puffy and slightly expanded. This second rise is key for those light, airy Sourdough Donuts.

Step 7: Heat Oil
In a heavy saucepan, pour enough vegetable or canola oil to fill about 3 inches deep. Heat the oil over medium heat until the thermometer registers 375°F. A good test is to drop a small piece of dough into the oil; if it sizzles immediately, you’re ready to fry!

Step 8: Fry Donuts
Carefully place the donuts into the hot oil, frying for about 1-2 minutes per side or until they turn a beautiful golden brown. Use a slotted spoon to flip them, ensuring they cook evenly. Once cooked, let them drain on paper towels to remove excess oil.

Step 9: Glaze
While the donuts cool slightly, prepare the glaze by whisking together 1 cup of powdered sugar, 2 tablespoons of milk, and a pinch of salt in a bowl. Once the donuts are warm, dip them into the glaze, coating them thoroughly, then place them on a wire rack to allow excess glaze to drip off and firm up.

Make Ahead Options

These Sourdough Donuts are perfect for busy home cooks looking to streamline their meal planning! You can prepare the dough up to 24 hours in advance by following the mixing and kneading steps, then refrigerate the covered bowl until you’re ready to fry. When you’re ready to serve, allow the dough to come to room temperature and rise for about 1 hour before cutting and frying. Alternatively, you can cut out the donuts ahead of time and place them on a parchment-lined sheet, covering them to refrigerate for up to 3 days until you’re ready to fry. This method ensures that each donut is just as fluffy and delicious as if made fresh that day!

Expert Tips for Sourdough Donuts

Perfect Yeast Activation: Ensure the milk is warm, not hot—temperature should be between 110-120°F to keep yeast alive and bubbly.
Flour Measurement: Be careful not to add too much flour; start with 3 cups and adjust as needed to achieve a soft dough that doesn’t stick to your hands.
Oil Temperature: Use a thermometer to maintain frying oil at 375°F; too hot and your donuts will burn, too cool and they’ll become greasy.
Allow Donuts to Rest: Letting the cut donuts rise for another hour before frying is crucial for achieving that light and airy texture in your Sourdough Donuts.
Customize Your Glaze: Feel free to experiment with different flavors by adding vanilla, cocoa powder, or even a touch of citrus zest to your glaze for a unique taste!

Fluffy Sourdough Donuts Recipe FAQs

How do I select the right sourdough discard?
Absolutely! When choosing your sourdough discard, look for a healthy starter that has been well-fed and bubbly before you store it. A heaping amount of about 6 oz will give your donuts a delightful tang, adding great flavor. Avoid discard that has a layer of liquid on top or any signs of dark spots; this could indicate that the starter is no longer fresh.

What’s the best way to store leftover Sourdough Donuts?
To keep your Sourdough Donuts fresh, store them in an airtight container at room temperature for up to 2 days. For longer storage, you can pop them in the fridge, where they will last about 5 days but may lose some fluffiness. If you want to keep them even longer, I recommend freezing them—see below for instructions!

How can I freeze Sourdough Donuts properly?
To freeze your Sourdough Donuts, wrap each one individually in plastic wrap to prevent freezer burn. Then, place them in a sealed freezer-safe bag. They can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw them overnight in the fridge. For the best texture, reheat them in the microwave for about 10 seconds or in a toaster oven until warmed through.

What should I do if my donuts are too greasy after frying?
If you find that your donuts are greasy, check the oil temperature during frying. The ideal frying temperature is around 375°F. If the oil is not hot enough, the donuts will absorb more oil, leading to a greasy texture. Using a thermometer can help you achieve perfect results every time. Also, ensure to drain the donuts properly on paper towels right after frying.

Can I make these donuts without eggs?
Absolutely! If you’re looking for an egg-free option, you can substitute each egg with a mixture of 1/4 cup of unsweetened applesauce or 1/4 cup of silken tofu blended until smooth. This change will maintain the moisture and help bind the ingredients together, creating a delightful result in your Sourdough Donuts!

What are some dietary considerations for Sourdough Donuts?
If you’re concerned about allergies, these Sourdough Donuts contain dairy and gluten due to the milk and flour. For a gluten-free option, you can substitute all-purpose flour with a gluten-free baking blend, making sure it contains xanthan gum. For lactose intolerance, use plant-based milk and dairy substitutes in place of butter for a delicious alternative!
