01 - Combine warm water and yeast in a large bowl. Let stand for 5 minutes until foamy.
02 - Add sugar, melted butter, milk, egg, vanilla, and salt to the yeast mixture. Whisk until well combined.

04 - Place dough in a lightly greased bowl, cover, and let rise in a warm area for 1 to 1.5 hours until doubled in size.
05 - Punch down the risen dough. Roll out on a floured surface to 1/2-inch thickness. Cut into strips approximately 1/2 inch wide by 4 inches long.
06 - Heat oil in a deep pot or fryer to 350°F.
07 - Fry dough strips in batches, turning occasionally, for 2 to 3 minutes until golden brown and puffed. Do not overcrowd the pot.
08 - Remove with a slotted spoon and drain on paper towels.
09 - Dust generously with powdered sugar while warm. Serve immediately.
