• 3 quarts vegetable oil for frying

Combine flour, yogurt, eggs, sugar, vanilla sugar, and salt in a large bowl; mix well. Set the dough aside for 30 minutes. Form dough into 2-inch balls. Heat vegetable oil to 365 degrees F (190 degrees C) in a large pot or deep fryer over high heat. Deep-fry sufganiyot, in batches, in hot oil until golden brown, about 3 minutes, turning them halfway through. Use a slotted spoon to transfer donuts to a paper towel-lined plate; repeat with remaining dough.
