Donut Dough
0 In a large mixing bowl, beat together the butter, maple sugar, salt, vanilla, and nutmeg. Beat for about a minute or two until it gets a little light and fluffy.
2 Add in the egg and beat until smooth. Finally add in the sour cream (or buttermilk) and beat again until smooth.
3 Place a sieve over the bowl and add in the flour, corn starch, and baking powder. Sift the dry ingredients into the wet and beat until just combined.
4 Scoop the dough onto a sheet of plastic wrap and wrap it into a square or circle that is about two inches thick.
5 Place the dough in the fridge to chill for at least an hour or up to overnight. If you want to make them for breakfast I love to prep the dough the night before and then fry and glaze in about 30 minutes in the morning.
Maple Glaze
28 Whisk the melted butter, maple syrup, and vanilla together.
29 Then add in the powdered sugar together in a bowl until it reaches a thick honey like consistency. You can add more maple syrup or powdered sugar to thin or thicken the glaze.
30 Note that the glaze will thin out/ melt a bit when it hits the warm donuts so don't make it too thin.
Shape the Donuts
31 While the dough is chilling or about 20 minutes before you plan to cut out the donuts, pour the oil into a large dutch oven and place a candy thermometer on the side of the pot.
32 Place the pot over medium low heat.
33 Place a wire rack into a baking sheet and set it next to the stove for the fried donuts to sit on.
34 Keep an eye on the oil temp but let it heat up to 370 F.
35 Once the dough has chilled, and the oil is at 350 F -360F, roll it out on a well floured surface. Be sure to scoot the dough around with a bench scraper and use enough flour on the counter between rolls to keep it from sticking.
37 Roll the dough out so that it is about 3/4" thick.
36 Use a biscuit cutter or a glass that is 4" inches in diameter and cut out 4-5 donuts. Use a smaller circle that's about 1" in diameter to cut out the donut holes. 
38 Pick up the dough scraps and quickly need them together until it becomes a smooth dough again. Re-wrap and place back in the fridge to stay cold.
Fry the Donuts
39 Once the oil has reached 370 F. Carefully place two of the donuts in the oil, dropping them away from you. Set a timer for 2 minutes and keep an eye on the oil temperature. It should stay between 360 and 370. *If your home is warm, place the extra donuts on a flour dusted baking tray into the fridge.
40 At first the donuts will sink, and then they'll float, and then they will start to puff and get that classic crack around the top.
41 As long as you are using a thermometer it's best to base the cook time on what these look like rather than an actual timer. The most important indicator is that the top has cracked all the way around.
42 Then use a fork in the center of the donut to carefully flip them over, away from you so the oil doesn't splash on to you.
43 Fry for about another 1 minute and 30 seconds until the second side of the donut has the same color as the first side.
44 Use the same fork to scoop the donuts out one at a time and place them on the wire rack to allow excess oil to drip off.
45 Let the oil come back to 370 before adding in the second round of donuts. Then repeat the frying steps above.
46 When you're frying the last two of the first round, re-roll the remaining dough and cut out 2-3 more donuts.
47 Fry the last batch and donut holes!
Glaze
48 While the donuts are still warm, I usually do this between batches, dunk the donuts, crack side down, into the glaze.
49 Carefully lift the glazed donut up with a fork in the center and let any excess glaze drip off.
50 Place the glazed donuts on a second wire rack and immediately sprinkle with flakey sea salt. Leave them to cool for at least ten minutes.
51 These are best eaten day of!
