Warm up your oven up to 100 f (low warm) and turn off. This is to prepare for a quick rise environment for your dough.
** TIP: avoid metal bowls and spoons, the magic of baking science works best if so!
Microwave milk for about 40 seconds, just warm to touch.Then add in yeast and the 1 tsp of sugar, mix and let sit a few minutes until frothy. In a seperate bowl, combine flour and salt.In another larger bowl mix together sugars, eggs and vanilla. Add the yeast mix to the sugar and eggs mixture, combine and then slowly start to add the flour mixture. Blend until a wet but cohesive dough forms.
Transfer to a lightly floured counter and knead for about 5 minutes until slightly elastic, you may need to add a little flour while you knead but remember you want it a little sticky at the end.
Put into an oiled bowl, cover tightly and place inside the warm (but off) oven. Let it rise double, mine only took about 30 minutes. Once risen, transfer back to the floured counter top, roll out and then cut your doughnut shapes. Place on to parchment lined baking sheets and return to that warm (but off) oven to rise again. approximately 20 minutes.
Begin to warm up the oil in the deep sided pan, over medium to medium high heat.
Carefully place doughnut (or hole) into oil, don't over crowd the oil. Cook on each side about one to two minutes, just until golden brown.
Sugar Icing Glazing: let the doughnut cool just a minute before dipping into the glaze.Cinnamon Sugar Dusting: immediately dip the hot doughnut into the cinnamon sugar dust for best coverage. Good luck eating just one!
