1. Activate the Yeast:
- In a large mixing bowl, combine the lukewarm milk and granulated sugar. Sprinkle the active dry yeast over the milk and let it sit for about 5-10 minutes until it becomes frothy, indicating the yeast is active.
2. Mix the Dough:
- To the yeast mixture, add the eggs, melted butter, and vanilla extract. Mix well to combine.
- Gradually add the flour and salt to the wet ingredients, stirring until a soft dough forms. You may not need to use all the flour, or you may need a little extra, depending on the humidity and temperature of your kitchen.
3. Knead the Dough:
- Turn the dough out onto a floured surface and knead for about 8-10 minutes until it’s smooth and elastic. Alternatively, you can use a stand mixer fitted with a dough hook attachment on medium speed.
4. First Rise:
- Place the dough in a greased bowl, turning it once to coat all sides with oil. Cover the bowl with a clean kitchen towel or plastic wrap and let the dough rise in a warm, draft-free place for about 1-1.5 hours, or until it has doubled in size.
5. Shape the Donuts:
- Once the dough has risen, punch it down gently to release any air bubbles. Turn it out onto a lightly floured surface and roll it out to about 1/2 inch thickness.
- Use a donut cutter or two differently sized round cutters to cut out the donuts and their holes. Transfer the cut donuts and holes to parchment-lined baking sheets, leaving space between each for the second rise.
6. Second Rise:
- Cover the shaped donuts loosely with a kitchen towel and let them rise again for about 30 minutes, or until they are puffy and have nearly doubled in size.
7. Fry the Donuts:
- Heat about 2 inches of vegetable oil in a deep fryer or large heavy-bottomed pot to 350°F (175°C). Fry the donuts in batches, being careful not to overcrowd the pot, for about 1 minute per side or until golden brown.
- Use a slotted spoon to transfer the fried donuts to a wire rack set over paper towels to drain excess oil.
8. Glaze or Decorate:
- While the donuts are still warm, you can glaze them, dip them in powdered sugar, or cover them with chocolate glaze. If you prefer filled donuts, you can also inject them with jam, custard, or cream using a piping bag and a narrow nozzle.
Enjoy your homemade donuts as a special treat for breakfast, dessert, or any time you crave something sweet and indulgent. The possibilities for toppings and fillings are endless, so have fun experimenting with your favorites!
