Ingredients

For the donuts:

  • Neutral high smoke point oil, for deep frying (e.g., canola)
  • 250g all purpose flour (2 cups), plus more for dusting
  • 4g salt (¾ teaspoon)
  • 9g baking powder (2 teaspoons)
  • 75g (½ cup) blueberries (fresh or frozen)
  • 45g melted butter (3 tablespoons), cooled slightly
  • 100g sugar (½ cup)
  • 50g egg (1 large) at room temperature
  • 120g plain unstrained yogurt (½ cup) at room temperature

For the glaze:

  • 35g (¼ cup) blueberries
  • 125g powdered sugar (1 cup)

Instructions

  1. Set up a safe fry station on your stove or a dedicated deep-fryer. Make sure it cannot be knocked over. Set over medium-low heat so it can heat gradually while you prep the donuts, and set up a deep fry thermometer. Keep a close eye on it, and aim for it to reach 350°F [180°C] by the time you’re ready to fry. If it heats too quickly, reduce the heat to low or turn off for a few moments until you’re ready.
  2. In a medium mixing bowl, combine the flour, salt, and baking powder. Whisk or sift together until completely lump free.
  3. If using fresh blueberries, make sure they’re completely dry. If using frozen, make sure not to thaw them first. Add your blueberries into the dry ingredients and toss around until coated in flour.
  4. In a separate mixing bowl, combine the melted butter, sugar, egg, and yogurt. Whisk together until completely smooth.
  5. Scrape the wet ingredients into the dry ingredients, then fold together just until combined (do not overmix).
  6. Dust a clean counter with more flour, then scrape the dough onto the dusted counter. Sprinkle on a little more flour, then gently pat it into an oval.* Take care to make sure it’s well dusted both underneath and on top. Roll it out to ½-inch thick, redusting above and below to keep it from sticking as you work.
  7. Stamp out as many donuts as you can using a donut stamp or set of pastry rings. Collect the scraps**, re-roll, and stamp out more donuts.
  8. Once the oil has heated, fry the donuts. They should take about 2 minutes per side at 350°F [180°C], and should be deeply brown (but not burnt) and cooked through. Remove to a paper-towel-lined plate or cooling-rack-lined sheet pan to cool.
  9. Make the glaze: combine the blueberries and powdered sugar in a small mixing bowl. Mash the blueberries on the side of the bowl until they fall apart and form a purple icing. Drizzle over the donuts.

Notes

* Do not knead the dough or incorporate the flour into it, or it will turn out dry—just pat it into shape.

** To get a really good re-roll out of the scraps, try not to let any flour touch the freshly stamped edges, and compress them together so the bare edges mush together with other bare edges. Try not to introduce a lot of new flour. Feel free to fry the donut holes, or re-roll them with the scraps (if you fry them, they will take about 30 seconds less per side).
