Whisk together the flour, sugar, instant yeast, and salt in a large bowl.

Mix in the warm buttermilk, eggs, melted butter, and vanilla extract until a soft dough forms.

Transfer your dough to a floured surface and knead for about 5 minutes until it’s smooth and elastic.

If it’s sticky, sprinkle a little more flour as you go.

Place kneaded dough in a greased bowl, cover with a clean towel, and let it rise in a warm place until doubled in size—about 1 hour.

Punch the dough down gently and roll it out to about 1/2-inch thick.

Use a round cutter or a glass to cut your doughnuts and a smaller cutter for the holes.

Heat about 2 inches of oil to 350°F (175°C) in a deep pot.

Drop the doughnuts in a few at a time, frying for about 1-2 minutes on each side until golden brown.

Use a slotted spoon to transfer them to a paper towel-lined plate.

Whisk together the powdered sugar, milk, and vanilla extract in a bowl for the glaze.

Dunk each warm doughnut into the glaze, swirling until well-coated.

Set aside on wire racks to let the glaze set.

Serve the Homemade Krispy Kremes fresh and warm.
