- 1 package (2 1/2 teaspoons) active dry yeast or 2/3 ounce (18 grams) fresh cake yeast
- 2/3 cup (160 grams) milk, at room temperature
- 3 1/2 cups (490 grams) unbleached all-purpose flour
- 1 1/3 cups (270 grams) sugar
- 2 teaspoons kosher salt
- 3 eggs
- 7 tablespoons (3/4 stick/100 grams) butter, at room temperature, cut into 6 to 8 pieces
- Canola oil, for frying
- 6 tablespoons (90 grams) heavy cream
- Pastry Cream , chilled
- In a stand mixer fitted with the dough hook, combine the yeast and milk. Stir together briefly, then let sit for about 1 minute to dissolve the yeast. Add the flour, 1/3 cup (70 grams) of the sugar, the salt, and the eggs and mix on low speed for about 1 minute, or until the dough comes together. Then, still on low speed, mix for another 2 to 3 minutes to develop the dough further. Now, begin to add the butter, a few pieces at a time, and continue to mix for 5 to 6 minutes, or until the butter is fully incorporated and the dough is soft and cohesive.
- Remove the dough from the bowl, wrap tightly in plastic wrap, and refrigerate for at least 6 hours or up to 15 hours.
- Lightly flour a baking sheet. On a well-floured work surface, roll out the dough into a 12-inch square about 1/2 inch thick. Using a 3 1/2- to 4-inch round biscuit cutter, cut out 9 doughnuts. Arrange them on the prepared baking sheet, cover with plastic wrap, and place in a warm spot to proof for 2 to 3 hours, or until they are about doubled in height and feel poufy and pillowy.
- When ready to fry, line a tray or baking sheet large enough to hold the doughnuts with paper towels. Pour oil to a depth of about 3 inches into a large, heavy saucepan and heat over medium-high heat until hot. To test the oil, throw in a pinch of flour. If it sizzles on contact, the oil is ready. (It should be 350 degrees if you are using a thermometer.) Working in batches, place the doughnuts in the hot oil, being careful not to crowd them. Fry on the first side for 2 to 3 minutes, or until brown. Then gently flip them and fry for another 2 to 3 minutes, or until brown on the second side. Using a slotted spoon, transfer the doughnuts to the prepared tray and let cool for a few minutes, or until cool enough to handle.
- Place the remaining 1 cup (200 grams) sugar in a small bowl. One at a time, toss the warm doughnuts in the sugar to coat evenly. As each doughnut is coated, return it to the tray to cool completely. This will take 30 to 40 minutes.
- To make the vanilla cream filling: While the doughnuts are cooking, whip the heavy cream until it holds stiff peaks. Using a rubber spatula, fold it into the pastry cream . You should have about 3 cups.
- When doughnuts are completely cooled, poke a hole in the side of each doughnut, spacing it equidistant between the top and bottom. Fit a pastry bag with a small round tip and fill the bag with the filling. Squirt about 1/3 cup filling into each doughnut. Serve immediately.
