Dough Ingredients
- 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 + 55 grams cornstarch
- 2 1/4 teaspoons baking powder
- 1 teaspoon salt
- 1/2 cup (80 grams) dried blueberries
Glaze Ingredients
- 1/2 cup milk
- 4 cups powdered sugar
- 1 teaspoon vanilla extract or vanilla bean paste
- Soften the Blueberries: Chop the dried blueberries into 3-4 pieces and place them in a bowl. Pour about half a cup of boiling water over them and let sit for 5 minutes until softened. Drain them in a fine mesh sieve to remove excess water.
- Prepare the Wet Mixture: In a bowl, melt the butter, then beat in the granulated sugar until fluffy. Add the sour cream, egg yolks, and vanilla extract, stirring until fully combined and smooth. Scrape down the bowl sides with a rubber spatula to incorporate all ingredients evenly.
- Mix Dry Ingredients and Combine: Add the cake flour (or all-purpose flour and cornstarch mixture), baking powder, and salt into the wet ingredients. Stir gently until the flour is mostly incorporated but not overmixed. Then fold in the softened, drained blueberries, stirring until no flour streaks remain and blueberries are evenly distributed.
- Chill the Dough: Transfer the dough onto a piece of plastic wrap and press it into a disk about 1-2 inches thick. Wrap it well and refrigerate for 1-2 hours or up to 24 hours. Chilling solidifies the butter and firms up the dough for easier handling.
- Roll Out and Cut Donuts: Lightly flour a clean surface, then roll out the chilled dough to about 1 inch thickness. Cut as many 3-4 inch circles as possible, then use a 1 inch cutter to cut out the centers, forming donut shapes. Gather the scraps, press together, and re-roll to cut more donuts, but avoid re-rolling more than twice to prevent toughness.
- Heat the Oil for Frying: Pour 3-4 inches of 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 over medium until the oil reaches 375°F (190°C).
- Fry the Donuts: Carefully place 2-3 donuts into the hot oil at a time. Fry the first side for 1 1/2 minutes; oil temperature will drop slightly when donuts are added. Flip with a long-handled fork and fry the second side for another 1 to 1 1/2 minutes until deep golden brown. Remove them and place on a baking rack set over a sheet pan to drain excess oil. Check one donut for doneness; adjust oil heat accordingly for remaining batches.
- Prepare the Glaze: Combine the milk, powdered sugar, and vanilla extract in a bowl. Whisk until smooth and pourable, adjusting the consistency with more milk or sugar if needed.
- Glaze the Donuts: While donuts are still slightly warm, dip the tops into the glaze or drizzle the glaze over each donut. Allow the glaze to set before serving for best texture and flavor.
Notes
- Use dried blueberries chopped and softened to avoid excess moisture in the dough.
- Do not overmix the batter to keep donuts tender and light.
- Chilling the dough is critical for firm dough that is easy to cut and reduces spreading during frying.
- Maintain oil temperature at 375°F; too hot will burn donuts, too cool will make them greasy and undercooked.
- Re-roll the dough no more than twice to avoid tough, chewy donuts.
- Glaze the donuts while warm for better adhesion and flavor absorption.
