Ingredients

Levain

  • 30 grams sourdough starter
  • 60 grams all-purpose flour
  • 60 grams filtered water

Brioche Sourdough Donut Dough

  • 2/3 cup active sourdough starter 150 g
  • 1/2 cup whole milk warm (100–110°F) (122 g)
  • 2 3/4 cups all-purpose flour 390 g
  • 2 large eggs room temperature (105 g)
  • 1/4 teaspoon salt 2 g
  • 1/4 cup granulated sugar 53 g
  • 1 teaspoon vanilla bean paste or vanilla extract 5 g
  • 8 tablespoons salted butter softened (113 g)

Vanilla Glaze

  • 2 cups powdered sugar (240 g)
  • 1/3 cup heavy cream (80 g)
  • 1 teaspoon vanilla bean paste or vanilla extract (5 g)

Instructions

Make the Levain

  • In a small bowl, mix together the sourdough starter, flour, and water.
  • Cover loosely and let rest at room temperature until bubbly and active, about 4–6 hours.

Prepare the Dough

  • Add all dough ingredients except the butter to the bowl of a stand mixer fitted with a dough hook.
  • Mix until the ingredients come together into a shaggy dough.
  • With the mixer running on low, add the softened butter one tablespoon at a time, allowing each piece to fully incorporate before adding the next.
  • Increase speed to medium to medium-high and knead for about 10 minutes, or until the dough is smooth, elastic, and pulling away from the sides of the bowl.

Bulk Fermentation

  • Transfer the dough to a large, lightly greased bowl.
  • Cover with plastic wrap and let bulk ferment overnight or 6–12 hours, depending on kitchen temperature. My kitchen is around 66℉ and takes the full 12 hours.
  • The dough should rise about 50–60%. (Brioche doughs are known to rise more slowly.)

Shape the Donuts

  • In the morning, turn the dough out onto a lightly floured surface.
  • Roll the dough to about 1/2-inch thickness.
  • Use a donut cutter to cut 12 donuts and 12 donut holes.
  • Place each donut onto an individual square of parchment paper and transfer to a baking sheet.

Final Rise

  • Cover loosely and let the donuts rise in a warm place until puffy, about 2–3 hours. To test if the dough is done rising, press your finger against a donut. If the indentation slowly springs back, the dough is fully fermented. If it springs back quickly, it needs more time.

Fry the Donuts

  • Add coconut oil (or another neutral oil) to a heavy-bottomed pan, filling it 2–3 inches deep.
  • Heat oil to 340–360°F, making sure to keep it within that range to avoid burning the donuts.
  • Fry donuts in batches for 1–2 minutes per side, until golden brown.
  • Transfer to a wire rack with parchment paper underneath to catch excess oil.

Glaze the Donuts

  • In a medium bowl, whisk together powdered sugar, heavy cream, and vanilla extract until smooth.
  • Dip the warm donuts into the glaze, then return to the wire rack to set. Allow the glaze to set before enjoying (or don't--they are that good!).

Notes

Storage
  • Store at room temperature in an airtight container for up to 2 days.
  • For the best texture, reheat unglazed donuts for 5–8 seconds in the microwave before glazing.
  • Freezing is best done before frying (after shaping).
