Sourdough Blueberry Donuts (Soft, Tangy & Naturally Sweet)
Sourdough Blueberry Donuts are a delicious twist on classic homemade donuts, combining the gentle tang of sourdough with the natural sweetness of juicy blueberries. These donuts are soft, fluffy, and bursting with flavor, making them perfect for breakfast, brunch, or a sweet afternoon treat. If you have an active sourdough starter or even leftover sourdough discard, this recipe is a wonderful way to transform it into something truly special.
The beauty of sourdough baking lies in its depth of flavor. Unlike traditional donuts made with commercial yeast, sourdough donuts develop a subtle tang and complex taste during fermentation. When paired with sweet blueberries and a light glaze or dusting of powdered sugar, the result is a perfectly balanced treat that feels both indulgent and homemade.
Another reason to love these donuts is their soft texture. The sourdough starter helps create a tender crumb while the blueberries add bursts of juicy flavor throughout each bite. Whether you choose to fry them for a classic donut experience or bake them for a lighter option, these donuts turn out beautifully every time.
This recipe is simple enough for home bakers yet impressive enough to serve to guests. With a little patience for the sourdough fermentation, you’ll be rewarded with donuts that taste far better than store-bought versions.
Ingredients
For the Dough
- 2 cups all-purpose flour
- ½ cup active sourdough starter (or sourdough discard)
- ¼ cup granulated sugar
- ½ teaspoon salt
- 1 teaspoon baking powder
- ½ cup milk
- 2 tablespoons unsalted butter, melted
- 1 large egg
- 1 teaspoon vanilla extract
- ¾ cup fresh or frozen blueberries
For Frying
- Vegetable oil (for frying)
Optional Glaze
- 1 cup powdered sugar
- 2–3 tablespoons milk
- ½ teaspoon vanilla extract
Preparation Time
- Prep Time: 20 minutes
- Resting/Fermentation Time: 1–2 hours
- Cooking Time: 10 minutes
- Total Time: about 2 hours 30 minutes
- Yield: 10–12 donuts
Step-by-Step Instructions
Step 1: Prepare the Dough
In a large mixing bowl, combine the sourdough starter, milk, sugar, egg, melted butter, and vanilla extract. Whisk until the mixture becomes smooth and well combined.
In another bowl, mix the flour, salt, and baking powder.
Gradually add the dry ingredients into the wet mixture while stirring until a soft dough forms.
Step 2: Add the Blueberries
Gently fold the blueberries into the dough. Be careful not to crush them too much, as you want the berries to remain whole and juicy inside the donuts.
If using frozen blueberries, add them directly from the freezer without thawing to prevent excess moisture.
Step 3: Let the Dough Rest
Cover the bowl with a clean towel or plastic wrap.
Allow the dough to rest at room temperature for 1–2 hours. This resting period helps the sourdough develop flavor and gives the donuts a lighter texture.
Step 4: Shape the Donuts
Lightly flour your work surface.
Roll the dough out to about ½ inch thickness.
Use a donut cutter or two round cutters (one large and one small) to cut out donut shapes.
Place the donuts on a parchment-lined tray and let them rest for another 20 minutes.
Step 5: Heat the Oil
Pour about 2–3 inches of vegetable oil into a deep pot or fryer.
Heat the oil to 350°F (175°C). Use a thermometer if possible to maintain the correct temperature.
Step 6: Fry the Donuts
Carefully place the donuts into the hot oil, frying only a few at a time to avoid overcrowding.
Fry each donut for about 1–2 minutes per side until golden brown.
Use a slotted spoon to remove them and place them on paper towels to drain excess oil.
Step 7: Prepare the Glaze
In a small bowl, whisk together powdered sugar, milk, and vanilla extract until smooth.
Dip each warm donut into the glaze or drizzle the glaze over the top.
Allow the glaze to set for a few minutes before serving.
Baking Option (Healthier Alternative)
If you prefer baked donuts instead of fried:
- Preheat your oven to 375°F (190°C).
- Lightly grease a donut pan.
- Spoon the dough into the pan, filling each cavity about ¾ full.
- Bake for 12–15 minutes until golden.
- Let cool slightly before glazing.
Baked donuts are slightly lighter but still soft and delicious.
Tips for Perfect Sourdough Donuts
Use an active starter
An active starter will give better flavor and texture.
Maintain oil temperature
If the oil is too hot, the donuts will burn outside while remaining raw inside.
Handle blueberries gently
Overmixing can cause the berries to burst and turn the dough purple.
Do not overcrowd the fryer
Cooking too many donuts at once can lower the oil temperature.
Serving Suggestions
These sourdough blueberry donuts taste amazing on their own, but you can also serve them with:
- A dusting of powdered sugar
- Lemon glaze
- Vanilla icing
- Maple glaze
- Fresh berries on the side
They pair beautifully with coffee, tea, or a glass of cold milk.
Storage Instructions
Room Temperature
