In a small bowl, combine the warm milk and yeast. Let it sit for 5-10 minutes until it’s foamy and smells like something’s happening.
In a large bowl, mix the flour, sugar, and salt. Make a well in the center and add the egg, vanilla, and melted butter.
Pour in the milk-yeast mixture. Stir until a sticky dough forms. If it's too dry, splash in a bit more milk. Too wet? Add a spoonful of flour.
Turn it onto a floured surface and knead until smooth—about 5 minutes. It’s a mini workout. Reward pending.
Place the dough in a greased bowl, cover with a kitchen towel, and let it rise in a warm place until doubled—about 1 hour. Take a coffee break.
Roll out the dough to about ½-inch thick. Cut into 2-inch squares (or circles—live your truth).
Heat oil in a deep pot to 350°F. Fry 2-3 at a time until golden on both sides, about 2 minutes each.
Drain on paper towels and while still warm, dust with as much powdered sugar as your sweet tooth desires.
