In a bowl, whisk together flour, baking powder, salt, and sugar.

In another bowl, beat the egg, then mix in milk and vanilla.

Combine the wet ingredients with the dry and stir until just combined. Batter should be thick and scoopable.

Preheat your air fryer to 375°F for 3 minutes. Line the basket with parchment or silicone liners.

Drop tablespoon-sized scoops of batter into the air fryer basket. Leave space between each scoop.

Air fry for 5–7 minutes until golden and puffed. Flip halfway through if needed.

Let cool slightly, then dust generously with powdered sugar. Serve warm.
