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
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
- Heat Liquid Mixture: Combine the heavy cream, whole milk, granulated sugar, and unsalted butter in a heat-proof bowl or measuring cup. Microwave in 20-second intervals, stirring between until the mixture reaches 130°F, ensuring the butter melts but the mixture doesn’t overheat.
- Prepare the Dough: In the bowl of a stand mixer, whisk together the flour, rapid rise yeast, and salt. Add the warm liquid mixture and mix with a dough hook until just combined. Then add the egg yolks and continue mixing until fully incorporated.
- Knead the Dough: Knead the dough on low speed for 5 minutes in the mixer. Transfer it to a lightly floured surface and knead by hand for 5 to 8 minutes until the dough is smooth, elastic, and springs back when gently pressed.
- First Rise: Shape the dough into a ball and place it in a large greased bowl. Cover the bowl and let the dough rest for 20 minutes to begin fermentation.
- Shape Donuts and Second Rise: Punch down the rested dough and roll it out to ½ inch thickness. Use a 3-inch round cookie cutter to cut out donut shapes. Place the donuts on a parchment-lined baking sheet, cover with a clean kitchen towel, and let them rise for about one hour or until nearly doubled in size.
- Heat Oil for Frying: While the donuts rise, heat vegetable oil in a large, heavy-bottomed pot to 360°F, using a candy thermometer to monitor the temperature. Maintain the oil temperature between 350°F and 375°F during frying for best results.
- Fry the Donuts: Carefully slide the risen donuts into the hot oil and fry each side for 2 to 3 minutes or until golden brown and cooked through. Avoid overcrowding the pot to keep the temperature consistent.
- Drain and Cool: Remove fried donuts with a spider or slotted spoon and place them on a cooling rack lined with paper towels to drain excess oil. Let them cool completely before filling.
- Make the Cream Filling: In a heavy-bottomed saucepan, whisk together sugar, cornstarch, and salt. Gradually whisk in milk and egg yolks until smooth. Heat over medium heat, whisking constantly, until the mixture thickens and boils, around 5 to 8 minutes, then continue cooking for another 1 to 2 minutes to fully cook the starch and eggs. Remove from heat, stir in butter and vanilla extract.
- Chill Cream Filling: Pour the custard into a heat-proof container and press plastic wrap directly on the surface to prevent a skin from forming. Refrigerate for at least 4 hours or overnight to chill and set the filling.
- Prepare Chocolate Ganache: Heat the heavy cream in the microwave for about 45 seconds, then pour over the chocolate chips in a bowl. Let sit for 2 to 3 minutes before stirring until the ganache is smooth and glossy.
- Fill Donuts: Using a piping bag, fill each cooled donut with the chilled cream filling.
- Dip Donuts in Ganache: Dip the tops of the filled donuts into the warm chocolate ganache, allowing the excess to drip off. Place on a wire rack until the chocolate sets.
Notes
- Maintaining correct oil temperature is crucial for evenly fried, non-greasy donuts.
- Use rapid rise yeast for faster rising times; traditional yeast will require longer fermentation.
- Press plastic wrap directly on the custard surface to prevent skin formation.
- Donuts should be completely cooled before filling to avoid melting the cream filling.
- If preferred, the donuts can be dusted with powdered sugar as an alternative topping.
