– **Granulated sugar**: 1/4 cup (50g)
– **Salt**: 1/2 teaspoon
– **Active dry yeast**: 2 1/4 teaspoons (1 packet)
– **Warm milk**: 1 cup (240ml)

For the Custard Filling:
– **Milk**: 2 cups (500ml)
– **Vanilla extract**: 1 teaspoon
– **Egg yolks**: 4 large
– **Granulated sugar**: 1/2 cup (100g)
– **Cornstarch**: 3 tablespoons
– **Unsalted butter**: 2 tablespoons

For the Sugar Glaze:
– **Granulated sugar**: 1 cup (200g)
– **Water**: 1/4 cup (60ml)
– **Vanilla extract**: 1 teaspoon (optional)

 Instructions:

Make the Donuts:
1. **Prepare the Dough:**
– In a large mixing bowl, combine 2 cups of flour, sugar, salt, and yeast.
– Add the warm milk, melted butter, and eggs. Mix until well combined.
– Gradually add the remaining flour, 1/2 cup at a time, until the dough is soft but not sticky.
– Knead the dough on a lightly floured surface for about 5-7 minutes, until smooth and elastic.

2. **Let the Dough Rise:**
– Place the dough in a greased bowl, cover it with a clean kitchen towel, and let it rise in a warm place for about 1 hour, or until doubled in size.

3. **Shape the Donuts:**
– Once the dough has risen, punch it down and roll it out to about 1/2 inch thick on a floured surface.
– Use a donut cutter or two round cutters (one larger, one smaller) to cut out the donuts.
– Place the donuts on a floured baking sheet, cover them, and let them rise again for about 30 minutes.

4. **Fry the Donuts:**
– Heat vegetable oil in a deep fryer or large, heavy-bottomed pot to 350°F (175°C).
– Fry the donuts in batches for about 1-2 minutes on each side, until golden brown.
– Use a slotted spoon to remove the donuts from the oil, and place them on a wire rack to drain.

Make the Custard Filling:
5. **Prepare the Custard:**
– In a medium saucepan, heat the milk and vanilla extract over medium heat until it just begins to simmer.
– In a separate bowl, whisk together the egg yolks, sugar, and cornstarch until smooth and pale.
– Gradually whisk the hot milk into the egg mixture to temper the eggs.
– Return the mixture to the saucepan and cook over medium heat, stirring constantly, until the custard thickens, about 3-5 minutes.
– Remove from heat and stir in the butter until smooth. Let the custard cool completely.

Fill the Donuts:
6. **Fill the Donuts:**
– Once the donuts are cool enough to handle, use a piping bag fitted with a long, narrow tip to fill each donut with the custard.
– Insert the tip into the side of each donut and squeeze the custard inside.

Make the Sugar Glaze:
7. **Prepare the Glaze:**
– In a small saucepan, combine the sugar and water. Heat over medium heat, stirring until the sugar dissolves.
– Remove from heat and stir in the vanilla extract, if using.

8. **Glaze the Donuts:**
– Dip the top of each filled donut into the sugar glaze, then return them to the wire rack to set.

9. **Serve:**
– Allow the glaze to set for a few minutes before serving. These donuts are best enjoyed fresh, with a soft and airy texture, creamy custard filling, and sweet glaze.
