Ingredients
  

For the Donuts

  • 150 grams Active starter
  • 4 Tbsps Milk
  • 2 Eggs (medium)
  • ¾ tsp Vanilla extract
  • 3½ Tbsps Granulated sugar
  • 2½ Cups All-purpose flour
  • Cinnamon & Nutmeg powder (to taste)
  • Pinch Salt
  • 3 Tbsps Unsalted butter (softened)

For the Glaze

  • 3 Cups Powdered sugar
  • 1 tsp Vanilla extract
  • 6 Tbsps Water

Instructions
 

  • Mix the starter, sugar, milk, eggs, and vanilla extract together while keeping the butter aside for now. Add the flour, nutmeg, cinnamon, and salt, then mix until the dough looks shaggy and the flour is mostly incorporated.
    Place the dough in the mixer on low speed for a few minutes. Check that no flour is visible on the bottom or sides of the bowl.
    Add the butter (softened) and mix until combined. Increase the speed to medium and allow the machine to mix the dough for about 7 minutes. The dough should feel soft but not sticky.

  • Cover the bowl and allow it to bulk ferment at room temperature. If your kitchen is between 22℃ (71℉) and 24℃ (75℉), this should take about 4 hours. You do not need to touch or fold the dough during this time.
    Once the dough has doubled in size, place the bowl in the fridge overnight (covered).

  • The next morning, move the dough to the counter and roll it out. Cut 14 medium donuts and their holes (you can make bigger donuts of course). Place them on parchment paper and cover with a towel to rest for another 2 to 3 hours.
    Brush or spray the donuts with olive oil or cooking oil.

  • Set the air fryer to 175℃ (350℉). Cook for 7 to 10 minutes, flipping halfway through. The first batch may take the full 10 minutes, while later batches might only need 7 minutes.

  • Remove the donuts and place them on a cooling rack. While they cool, mix the granulated sugar, water, and vanilla together to create the glaze.
  • To glaze, drop each donut into the mixture, flip it, and shake off the excess. Place them back on the rack to dry. If you want a thicker coating, let the first layer set completely before doing a second dip.
