Ingredients
Scale
Dough
- 3 cups all-purpose flour
- 1/4 cup granulated sugar
- 2 1/4 tsp active dry yeast
- 1 cup whole milk (warm)
- 1/4 cup unsalted butter (melted)
- 2 large eggs
- 1 tsp vanilla extract
- 1/2 tsp salt
Custard Filling
- 2 cups whole milk
- 4 egg yolks
- 1/4 cup cornstarch
- 1/2 cup sugar
- 1 tsp vanilla extract
Chocolate Ganache
- 1/2 cup heavy cream
- 1 cup semisweet chocolate chips
Frying
- Vegetable oil (enough for frying, about 4 cups)
Instructions
- Prepare the Dough: In a small bowl, combine warm milk, sugar, and active dry yeast. Stir gently and let it sit for about 5-10 minutes until frothy, indicating the yeast is active. In a large mixing bowl, combine flour, salt, eggs, melted butter, vanilla extract, and the yeast mixture. Mix until you form a sticky dough.
- Knead the Dough: Turn the dough out onto a floured surface and knead for approximately 5 minutes until it becomes smooth and elastic. Form a ball and place it into a greased bowl. Cover with a clean kitchen towel or plastic wrap and let it rise in a warm place until doubled in size, about 1 hour.
- Shape and Second Rise: Once risen, roll out the dough to about 1/2-inch thickness. Use a round cutter (3 inches diameter) to cut the dough into circles. Place the rounds on a floured surface or parchment-lined tray, cover, and let rise again for about 30 minutes until puffed.
- Fry the Donuts: Heat vegetable oil in a deep pot or deep fryer to 350°F (175°C). Carefully fry the donuts in batches, cooking each side for about 2 minutes or until golden brown. Use a slotted spoon to remove and place them on paper towels to drain excess oil. Let them cool completely before filling.
- Make the Custard Filling: In a saucepan, whisk together egg yolks, sugar, and cornstarch until smooth. Gradually add the milk while whisking. Cook over medium heat, stirring constantly, until the mixture thickens and comes to a gentle boil. Remove from heat and stir in vanilla extract. Transfer to a bowl, cover with plastic wrap directly on the surface to prevent a skin, and chill until set.
- Fill the Donuts: Using a small knife or a piping tip, carefully cut a hole or make a slit in the side of each donut. Fill a piping bag with the chilled custard and inject it into the center of each donut until filled.
- Prepare the Chocolate Ganache: In a small saucepan, warm the heavy cream until it just starts to simmer. Remove from heat and add the semisweet chocolate chips. Let sit for 1-2 minutes, then stir until smooth and glossy.
- Glaze the Donuts: Dip the top of each filled donut into the warm ganache or drizzle the ganache over the donuts using a spoon. Allow the ganache to set before serving.
Notes
- Ensure the oil maintains a consistent temperature (350°F) to avoid greasy or undercooked donuts.
- Use room temperature ingredients for better dough consistency and rise.
- To store, keep donuts refrigerated in an airtight container for up to 2 days; best eaten fresh.
- Allow the custard to fully cool before filling to prevent melting the dough.
- For a dairy-free alternative, substitute milk and cream with plant-based options.
