Mix together the flour, cinnamon, nutmeg, baking soda, baking powder, and salt in a big bowl. Put aside for later.
02 -
With an electric mixer, beat the sugar, butter, and egg yolks for a couple of minutes until smooth and fluffy.
03 -
Add the sour cream into the fluffy sugar and butter mixture. Stir until it feels silky and everything blends in.
04 -
On a low speed, fold the dry mixture into the wet one bit by bit. Stop as soon as they come together—don’t overwork it or the donuts might lose their tenderness.

Wrap the dough in some plastic wrap and pop it in the fridge for an hour or more. It'll firm up and be easier to roll out.
06 -
Take the chilled dough and roll it flat on a floured counter until it’s about 1 cm thick. Cut out your donut shapes (and holes) with a donut cutter. If you’d like, add 3 small triangle cuts around the edges for a classic cracked look.
07 -
Use a large pot or deep fryer to warm up the oil until it hits 350°F (175°C). Keep track of the heat with a thermometer so it doesn’t get too high or low.
08 -
Gently lower the donuts into the hot oil, a few at a time so they don’t crowd each other. Fry them for about 1 to 1½ minutes on both sides until they’re a nice golden shade. Smaller pieces, like the donut holes, will fry faster.
09 -
Pull the donuts from the oil using a slotted spoon. Place them on paper towels to soak up any extra oil, and let them cool slightly.
10 -
As the donuts cool, whisk the salt, milk, and powdered sugar together in a bowl until you’ve got a smooth glaze. Add more milk or sugar if the consistency’s not quite right.
11 -
Take each donut and dip just the top into the glaze. Let the extra drip off, then place them on a wire rack over a baking sheet to set. Once the glaze hardens, they’re ready to go!
