In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt.
In a separate bowl, whisk together the eggs and milk until combined and slightly frothy.
Pour the wet ingredients into the dry ingredients and mix gently until smooth.
Pour batter into a glass measuring cup or squeeze bottle for easier pouring.
Heat the oil to 375°F (190°C) in a heavy-bottomed deep skillet or Dutch oven.
Swirl the batter into the hot oil starting from the center and moving outward to form a round shape.
Fry for 1-2 minutes on each side until golden brown.
Drain on paper towels and dust with powdered sugar while warm.
Repeat with the remaining batter and serve immediately.
