Slice 1/4 off the top and bottom of each soufganiyote to reveal the dry bread inside.
Mix the eggs, milk, sugar, vanilla and salt in a medium size bowl.
Heat a nonstick frying pan over medium heat and spray with cooking spray.
Submerge soufganiyote into the egg mixture, allow excess to drip off and fry 1-2 minutes on each side until brown and crispy. Stand up on the side and turn 3-4 times until browned entirely.
Sprinkle with powdered sugar. Serve warm.
