Jelly-Filled Donut is a type of donut, with jelly inside.
- 2 tablespoons active dry yeast
- 1/2 cup milk (100 degrees to 110 degrees)
- 1/3 cup + 1 teaspoon sugar
- 2 1/4 cups all-purpose flour
- 3 large egg yolks
- 2 tablespoons unsalted butter, room temperature
- 2 teaspoons salt
- 3 cups vegetable oil
- 1 cup seedless raspberry jam
Place yeast, warm milk, and 1 teaspoon sugar in a small bowl. Set aside until foamy and doubled in size, about 15 minutes.
Place flour in a large bowl. Create a well in the center and add eggs, yeast mixture, 1/4 cup sugar, butter, and salt. Using a wooden spoon, stir dough starts to come together and is sticky. Flour a work surface and knead until dough is smooth, soft, and bounces back when poked with a finger, about 8 minutes (add more flour if necessary). Place in a lightly oiled bowl; cover with plastic wrap. Set in a warm place to rise until doubled, 1 to 1 1/2 hours.
Lightly flour a work surface, roll dough to 1/4-inch thickness. Using a 2 1/2-inch-round cutter, cut 20 rounds. Cover with plastic wrap; let rise 15 minutes.
In medium saucepan over medium heat, heat oil until a deep-frying thermometer registers 370 degrees. Using a slotted spoon, carefully slip 2 rounds into oil. Fry until golden, about 40 seconds. Turn doughnuts over; fry until golden on other side, another 40 seconds. Using a slotted spoon, transfer to a paper-towel-lined baking sheet. Roll in sugar while warm. Fry all dough, and roll in sugar.
Fill a pastry bag fitted with a #4 tip with jam. Using a wooden skewer or toothpick, make a hole in the side of each doughnut. Fit the pastry tip into a hole, pipe about 2 teaspoons jam into doughnut. Repeat with remaining doughnuts.
