To make these delectable treats, you will need the following ingredients:

– 2 1/4 cups of all-purpose flour
– 1/4 cup of granulated sugar
– 1/2 teaspoon of salt
– 1 package of active dry yeast
– 1/2 cup of milk
– 1/4 cup of water
– 3 tablespoons of butter, melted
– 1 egg
– 1 teaspoon of vanilla extract
– Vegetable oil, for frying

For the filling, you will need:
– 1 cup of milk
– 1/4 cup of sugar
– 2 tablespoons of cornstarch
– 1/4 teaspoon of salt
– 1 egg
– 1 teaspoon of vanilla extract

Start by mixing the flour, sugar, salt, and yeast in a large bowl. In a separate bowl, heat the milk, water, and butter until warm. Add the wet ingredients to the dry ingredients and mix until a dough forms. Knead the dough for about 5 minutes, then cover and let it rise for 1 hour.

While the dough is rising, prepare the custard filling. In a saucepan, heat the milk, sugar, cornstarch, and salt over medium heat. In a separate bowl, whisk the egg and vanilla extract. Slowly pour the hot milk mixture into the egg mixture, whisking constantly. Return the mixture to the saucepan and cook until thickened. Remove from heat and let cool.

Once the dough has risen, roll it out on a floured surface to 1/2 inch thick. Cut the dough into long rectangles, then let them rise for another 30 minutes. Heat the vegetable oil in a deep fryer or large pot to 375°F. Fry the donuts for 2-3 minutes on each side, until golden brown. Remove from the oil and let them cool on a wire rack.

To fill the donuts, make a small slit on one side and pipe the custard filling inside. Sprinkle powdered sugar on top for an extra touch of sweetness.
