Prep Time 20 minutes
Cook Time 12 minutes
Course Breakfast, Dessert
Servings 16 donuts


For the Donuts:

  • 2 cups 250g all-purpose flour, spooned and leveled
  • 1 tablespoon baking powder
  • ½ teaspoon salt
  • 1 teaspoon ground cardamom optional
  • cups 9oz fresh blueberries
  • 1 tablespoon 8g all-purpose flour (for tossing the blueberries)
  • ½ cup 112g unsalted butter, melted
  • 1 cup 200g granulated sugar
  • 2 large eggs at room temperature
  • 1 teaspoon vanilla extract
  • ½ cup 122g sour cream, at room temperature
  • ½ cup 120ml whole milk, at room temperature

For the Blueberry Glaze:

  • 2 cups 260g powdered sugar
  • 2 tablespoons blueberry jam
  • 1 teaspoon vanilla extract
  • 2-3 tablespoons milk


For the Donuts:

  • Preheat your oven to 350°F. Grease a donut pan and set it aside.
  • In a small bowl, whisk together the flour, baking powder, salt, and cardamom (if using). Set aside.
  • In another small bowl, toss the blueberries with 1 tablespoon of flour to coat them. This helps prevent them from sinking to the bottom while baking.
  • In a large bowl, whisk together the melted butter, sugar, eggs, vanilla, sour cream, and milk.
  • Add the dry ingredients to the wet ingredients and mix until just combined.
  • Gently fold in the blueberries with a rubber spatula.
  • Transfer the batter to a piping bag and cut off the tip. Pipe the batter into the prepared donut pan, filling each well about three-quarters full.
  • Bake for 11-12 minutes. Let the donuts cool in the pan for 10 minutes, then transfer them to a wire rack to cool completely. Repeat with the remaining batter.

For the Glaze:

  • In a large mixing bowl, combine the powdered sugar, blueberry jam, vanilla, and milk. Whisk until smooth. Start with 2 tablespoons of milk and add more if needed to reach the desired consistency.
  • Dip each cooled donut into the glaze and place back on the wire rack. Let the glaze set for about 30 minutes before serving.


Store leftovers in an airtight container for up to three days.
