01 - In a large bowl, whisk together flour, granulated sugar, baking powder, and salt until evenly distributed.
02 - In a separate bowl, whisk milk, egg, melted butter, and vanilla extract until fully incorporated and smooth.
03 - Pour the wet mixture into the dry ingredients and stir until a soft, cohesive dough forms. Avoid overmixing.
04 - Turn dough onto a lightly floured surface and roll to 1/4-inch thickness. Cut strips approximately 1/2 inch wide and 3 inches long, resembling fry shapes.
05 - Heat vegetable oil in a deep fryer or heavy-bottomed pot to 350°F. Use a kitchen thermometer to verify temperature.
06 - Fry dough strips in small batches, turning occasionally, until golden brown and puffed throughout, about 2-3 minutes per batch. Maintain oil temperature between batches.
07 - Remove with a slotted spoon and transfer to paper towels to drain excess oil.
08 - While still warm, generously dust the beignet fries with powdered sugar, coating all sides evenly.
09 - Serve right away while warm and crispy for optimal texture and flavor.
