Glazed yeast donuts are the BEST donuts you'll ever eat. I've been making this easy glazed donut recipe for years and can honestly tell you it's PERFECT!
Warm the milk until it is about 105 degrees F. Add the milk to a mixing bowl or the bowl of your stand mixer. Add the sugar and stir to dissolve. Add the yeast and stir to combine. Let the yeast rest for 5 minutes.
Remove the dough from the fridge and roll it out on a lightly floured surface until it is 1/2 to 1/3 of an inch thick. Use a three-inch donut cutter to cut out the donuts.
Heat a few inches of oil or shortening in a large cast iron skillet or fryer over medium heat until the oil reaches 350 to 375 degrees (use a thermometer for accuracy). Carefully add the donuts to the hot oil and fry until golden brown, about 90 seconds per side. The donut holes will only take about 30 seconds per side.
Melt the butter in a medium bowl. Add the vanilla and stir to combine. Add the powdered sugar and stir to form a thick paste. Thin out the paste with milk, one tablespoon at a time, until the mixture is about as thick as school glue.
