In a mixing bowl, whisk together the flour, granulated sugar, baking powder, and salt until well combined.

In a separate bowl, mix the milk, egg, and vanilla extract until you achieve a smooth consistency.

Carefully fold the wet mixture into the dry ingredients, being cautious not to overmix.

In a deep fryer or heavy pot, heat vegetable oil to 350°F (175°C).

Drop spoonfuls of the batter into the hot oil, frying for 2-3 minutes or until they turn a lovely golden brown.

Use a slotted spoon to take the beignets out, allowing excess oil to drain onto paper towels.

Generously dust with powdered sugar before serving.
