Prepare the Dough

In a medium saucepan, combine the water, butter, salt, and sugar.

Bring the mixture to a rolling boil over high heat.

Once boiling, reduce the heat to low and stir in the flour all at once.

Continue stirring vigorously until the dough pulls away from the sides of the pan and forms a smooth ball.

Remove the pan from heat and let it sit for 4–5 minutes to cool slightly.

Add the Egg and Flavoring

Transfer the warm dough to a mixing bowl.

Add the vanilla essence and egg.

Using a hand mixer (or stand mixer), beat until the egg is fully incorporated and the dough becomes smooth and pipeable.

Pipe the Churros

Spoon the dough into a piping bag fitted with a large star tip.

Preheat your air fryer to 375°F (190°C).

Lightly spray the air fryer basket with nonstick cooking spray.

Pipe small 1- to 2-inch sections directly into the basket, leaving room between each bite for airflow.

Alternatively, you can use a spoon to drop dough portions into the basket.

Air Fry

Lightly brush the tops of the piped churros with melted butter (optional) for extra crispness.

Air fry for 10–12 minutes, or until golden brown and crispy.

Work in batches as needed—avoid overcrowding.

Coat in Cinnamon Sugar

While the churros are still warm (but not hot), mix together the white sugar and cinnamon powder in a shallow bowl.

Toss each churro bite in the cinnamon-sugar mixture until evenly coated.

If needed, lightly mist the churros with spray oil or melted butter so the coating sticks better.

Serve

Serve the churro bites warm with chocolate sauce, dulce de leche, Nutella, or even whipped cream.

Enjoy immediately for the best texture and flavor!
