Sourdough Glazed Donuts (Light, Fluffy & Naturally Fermented)
If you love the classic glazed donut but want deeper flavor and a softer crumb, these Sourdough Glazed Donuts are the ultimate treat. The natural fermentation from sourdough starter creates a tender texture, slight tang, and incredible depth you simply can’t get from commercial yeast alone.
These donuts fry up golden and airy, then get dipped in a silky vanilla glaze that crackles slightly as it sets — just like your favorite bakery-style donuts.
🛒 Ingredients (Makes 10–12 Donuts)
For the Dough:
-
½ cup active sourdough starter (bubbly and fed)
-
¾ cup warm milk
-
¼ cup granulated sugar
-
2 large eggs
-
¼ cup unsalted butter, softened
-
1 tsp vanilla extract
-
3–3½ cups all-purpose flour
-
½ tsp salt
For Frying:
-
Neutral oil (vegetable or canola)
For the Glaze:
-
2 cups powdered sugar
-
3–4 tbsp milk
-
1 tsp vanilla extract
-
Pinch of salt
👩🍳 Instructions
1️⃣ Make the Dough
In a large bowl, combine active sourdough starter, warm milk, sugar, eggs, butter, and vanilla.
Gradually add flour and salt. Mix until a soft dough forms.
Knead for 8–10 minutes until smooth and elastic. The dough should be soft but not sticky.
2️⃣ First Rise (Slow Fermentation)
Place dough in a greased bowl, cover, and let rise at room temperature for 4–6 hours until doubled.
For deeper flavor, refrigerate overnight (8–12 hours). Cold fermentation improves texture and taste.
3️⃣ Shape the Donuts
Roll dough on a lightly floured surface to about ½ inch thickness.
Use a donut cutter (or round cutters) to shape.
Place on parchment-lined tray. Cover loosely and let rise 1–2 hours until puffy.
4️⃣ Fry
Heat oil to 175°C (350°F).
Fry donuts 1–2 minutes per side until golden brown.
Remove to paper towel-lined tray.
Let cool slightly before glazing.
5️⃣ Glaze
Whisk powdered sugar, milk, vanilla, and salt until smooth.
Dip warm (not hot) donuts into glaze. Place on rack and allow glaze to set.
