01 - In a large bowl, whisk together flour, granulated sugar, baking powder, and salt until evenly combined.
02 - In a separate bowl, whisk milk, egg, melted butter, and vanilla extract until well blended and smooth.
03 - Pour the wet ingredients into the dry ingredients. Mix thoroughly until a soft, pliable dough forms.
04 - Turn the dough onto a lightly floured surface. Roll out to approximately 1/4-inch thickness. Cut into strips about 1/2 inch wide and 3 inches long to resemble fries.
05 - Heat vegetable oil in a deep fryer or heavy-bottomed pot to 350°F.
06 - Fry the dough strips in batches, turning occasionally, until golden brown and puffed, about 2-3 minutes per batch.
07 - Remove with a slotted spoon and drain on paper towels to remove excess oil.
08 - While still warm, dust generously with powdered sugar, coating all sides evenly.
09 - Serve immediately while warm for optimal taste and texture.
