Ingredients

Scale

Dough

½ cup heavy cream
½ cup whole milk
¼ cup granulated sugar
¼ cup unsalted butter
3 ¼ cups all-purpose flour
2 packets rapid rise yeast (about 4 ½ teaspoons)
1 teaspoon salt
2 egg yolks
Vegetable oil for frying (about 4 cups or enough for deep frying)

Cream Filling

¼ cup granulated sugar
1 ½ tablespoons cornstarch
1 pinch salt
1 ¼ cups whole milk
1 large egg yolk
1 tablespoon unsalted butter
1 teaspoon vanilla extract

Chocolate Ganache

4 ounces semi-sweet chocolate chips
⅓ cup heavy whipping cream

Instructions

Prepare the liquid ingredients: Combine the heavy cream, whole milk, granulated sugar, and unsalted butter in a heat-proof bowl or measuring cup. Heat in the microwave in 20-second intervals, stirring if needed, until the mixture reaches 130°F to properly activate the yeast.
Mix dry ingredients: In the bowl of a stand mixer fitted with a dough hook, combine the all-purpose flour, rapid rise yeast, and salt. Add the warm liquid mixture and mix until just combined. Then add the two egg yolks and continue mixing to incorporate.
Knead the dough: Knead the dough on low speed for 5 minutes using the stand mixer. Remove the dough and transfer to a lightly floured surface. Knead by hand for an additional 5-8 minutes until the dough is smooth and elastic, and springs back when poked.
First rest: Shape the dough into a ball and place it in a large greased bowl. Cover with a towel or plastic wrap and let it rest for 20 minutes to relax the gluten and start rising.
Shape and proof: Punch down the rested dough to release air. Roll it out to approximately ½ inch thickness. Use a 3-inch round cookie cutter to cut out donut shapes and transfer them to a parchment-lined baking sheet. Cover with a clean kitchen towel and allow to rise for about 1 hour, or until nearly doubled in size.
Heat the oil: Begin heating vegetable oil in a heavy-bottomed large pot or deep fryer to 360°F, monitoring with a candy or deep-fry thermometer. Maintain the oil temperature between 350°F and 375°F during frying for optimum results.
Fry the donuts: Carefully place donuts in the hot oil and fry for 2 to 3 minutes per side until they turn golden brown. Avoid overcrowding the pan to keep the temperature steady.
Drain and cool: Remove fried donuts with a slotted spoon or spider and place on a cooling rack set over paper towels to drain excess oil. Allow them to cool enough to handle safely.
Prepare cream filling: For the custard filling, whisk together granulated sugar, cornstarch, and salt in a heavy-bottomed saucepan. Add whole milk and egg yolk, whisking until smooth.
Cook custard: Heat the mixture over medium heat, whisking constantly until it thickens and begins to bubble, about 5 to 8 minutes. Continue cooking and whisking for another 1 to 2 minutes for full thickening.
Finish custard: Remove from heat and whisk in the butter and vanilla extract until smooth. Pour into a heat-proof container and press plastic wrap directly on the surface to prevent skin from forming. Chill in the refrigerator for at least 4 hours or overnight.
Make chocolate ganache: Heat heavy whipping cream in the microwave for about 45 seconds until hot but not boiling. Pour it over the semi-sweet chocolate chips and let sit for 2 to 3 minutes, then stir until the mixture is smooth and glossy.
Fill donuts and glaze: Once donuts are cool, fill them with the chilled cream filling using a piping bag or spoon. Dip the tops of the filled donuts into the chocolate ganache to coat evenly. Allow the ganache to set slightly before serving.

Notes

Maintaining the oil temperature around 360°F is key to cooking donuts fully without absorbing excess oil.
Ensure the dough is kneaded well for a light, fluffy texture.
Pressing plastic wrap directly on custard helps avoid an undesirable skin.
Use a candy or deep-fry thermometer to monitor oil temperature precisely.
For best flavor, chill the cream filling overnight before assembling.
Donuts are best enjoyed fresh but can be stored covered at room temperature for 1 day or refrigerated for 2-3 days.
