Step 7. Heat Oil:
- Pour 2–3 inches of oil into a heavy pot and heat to 350°F (175 °C). Use a thermometer for accuracy.
Step 8. Fry the Donuts:
- Carefully fry 2–3 donuts at a time until golden brown—about 1 minute per side. Fry holes for 30 seconds on each side.
- Use a slotted spoon to transfer to a wire rack lined with paper towels.
Step 9. Make the Glaze:
- Whisk powdered sugar, milk, and vanilla until smooth and slightly thick but pourable.
Step 10. Glaze the Donuts:
- Dip warm donuts into the glaze, coating fully. Place back on wire rack (with parchment underneath to catch drips). Let the glaze set.
Step 11. Serve:
- Enjoy immediately for the softest texture! Store in an airtight container for up to 2 days (glaze may soften).
Tips for Pillowy Perfection:
- Use a thermometer to keep oil at a steady 350°F—too hot browns outside too fast, too cool leads to greasy donuts.
- Let the first rise complete to avoid a dense texture.
- Warm milk slightly for maximum yeast activation—but not too hot (hot = kills yeast!).
- Glaze while donuts are warm for that perfect shiny coat and melt-in-your-mouth softness.
