In a saucepan, combine water, butter, sugar, and salt. Bring to a boil over high heat.

Reduce heat and add flour gradually, stirring continuously until a smooth dough forms. Remove from heat.

Let the dough cool for 4–5 minutes, then transfer to a mixing bowl.

Add the egg and vanilla essence, and mix using a hand mixer until smooth.

Transfer the dough into a piping bag.

Preheat the air fryer to 375°F (190°C) and lightly grease the basket.

Pipe small portions of dough into the basket without overcrowding.

Lightly brush with butter and cook for 10–12 minutes until golden brown. This Sweet Air Fryer Churro Bites Recipe ensures even crispiness.

Mix sugar and cinnamon in a bowl.

Toss warm churro bites in the cinnamon sugar until evenly coated.

Serve immediately with your favorite dips.
