1. Prepare the Dough:
   • In a large bowl, whisk together flour, salt, and sugar.
   • In a separate bowl, combine warm milk, yeast, egg, and melted butter.
   • Gradually add the wet mixture to the dry ingredients, stirring until a shaggy dough forms.
   • Turn the dough onto a lightly floured surface and knead for 2-3 minutes until smooth and elastic.
2. Proof the Dough:
   • Place the dough in a lightly greased bowl, cover with a damp towel, and let it rise in a warm place for 1-2 hours, or until doubled in size.
3. Shape the Beignets:
   • Roll out the dough to 1/4-inch thickness on a floured surface.
   • Cut into 2-inch squares (or desired shape).
   • Place shapes on a parchment-lined baking sheet and let them rest for 30 minutes.
4. Fry the Beignets:
   • Heat oil to 360°F in a deep fryer or heavy-bottomed pot.
   • Fry the beignets in small batches for 3-5 minutes, turning once, until golden brown.
   • Drain on paper towels.
5. Finish and Serve:
   • While still warm, dust the beignets generously with powdered sugar.

Serve immediately and enjoy with a café au lait or your favorite drink.
