After chilling, the donuts are rolled out, cut, and fried to a perfect golden brown, then dipped in a sweet vanilla glaze that adds the perfect finishing touch. Ideal for a special breakfast or an indulgent snack.

Ingredients

Scale

Donut Dough

  • 3 Tablespoons (42 grams) butter, melted
  • 2/3 cup (132 grams) granulated sugar
  • 2 large egg yolks
  • 1 teaspoon vanilla extract or vanilla bean paste
  • 2/3 cup (160 grams) sour cream
  • 3 1/4 cups (370 grams) cake flour or 315 grams all-purpose flour plus 55 grams cornstarch
  • 2 1/4 teaspoons baking powder
  • 1 teaspoon salt
  • 1/2 cup (80 grams) dried blueberries

Glaze

  • 1/2 cup milk
  • 4 cups powdered sugar
  • 1 teaspoon vanilla extract or vanilla bean paste

Instructions

  1. Prepare Blueberries: Chop the dried blueberries into 3-4 pieces and place them in a bowl. Pour about half a cup of boiling water over the blueberries and let them soak for 5 minutes until softened. Drain them using a fine mesh sieve and set aside.
  2. Make the Dough: In a bowl, melt the butter, then beat in granulated sugar until fluffy. Add sour cream, egg yolks, and vanilla extract or vanilla bean paste, stirring until well combined. In a separate bowl, whisk together cake flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, stirring until mostly incorporated. Fold in the drained blueberries until fully distributed, making sure no flour streaks remain.
  3. Chill the Dough: Transfer the dough onto a plastic wrap disc, press to flatten it to 1-2 inches thick, wrap tightly, and refrigerate for 1-2 hours or up to 24 hours. Chilling solidifies the butter, creating easier-to-handle dough.
  4. Roll and Cut Donuts: Once chilled, flour a work surface and roll the dough out to about 1-inch thickness. Use a 3-4 inch round cutter to cut out donuts, then use a 1-inch cutter to cut out the donut holes. Gather and re-roll the remaining dough once or twice for additional donuts—avoid over-rolling to prevent toughness.
  5. Heat Oil for Frying: Pour 3-4 inches of a neutral, high smoke point oil (such as canola, vegetable, peanut, sunflower, or avocado oil) into a medium pot with high sides. Attach a candy/fry thermometer and heat the oil over medium heat until it reaches 375°F (190°C).
  6. Fry the Donuts: Carefully lower 2-3 donuts into the hot oil. Fry for 1 1/2 minutes on the first side, then using a long-handled fork, turn and fry for another 1 to 1 1/2 minutes until the donuts are golden brown. Remove donuts and place them on a wire rack set over a baking sheet to drain excess oil. Adjust oil temperature between batches as needed to ensure even cooking.
  7. Prepare the Glaze: In a small pot, heat 1/2 cup milk until steaming but not boiling. Gradually whisk in 4 cups powdered sugar until the glaze is smooth and runs easily but is not too thin or milky. Stir in 1 teaspoon vanilla extract or vanilla bean paste.
  8. Glaze the Donuts: Dip each cooled donut into the glaze, flipping to coat both sides. Allow excess glaze to drip off, then place back on the wire rack to set. Use a fork to dip and lift the donuts to avoid messy hands.

Notes

  • Do not re-roll the dough more than twice to avoid tough and chewy donuts.
  • Use a candy/fry thermometer to maintain consistent oil temperature around 375°F for perfect frying.
  • Dry blueberries can be substituted with fresh blueberries, but reduce soaking and moisture to prevent sogginess.
  • Ensure glaze thickness is right—runny enough to coat but thick enough not to drip excessively.
  • Can store leftover donuts unglazed and reheat lightly before glazing for fresh taste.
