In a medium saucepan over medium-high heat, bring the water, butter, sugar, and salt to a boil.
Reduce heat to low and stir in the flour, mixing continuously until a smooth dough forms.
Transfer the dough to a mixing bowl and let it cool for 5 minutes.
Add the vanilla extract and eggs to the cooled dough, then blend with an electric mixer until fully combined and smooth.
Transfer the dough to a piping bag fitted with a small star tip and pipe 4-inch lengths onto a parchment-lined tray.
Freeze the piped churros for a couple of hours until firm.
Lightly coat the air fryer basket with oil spray and arrange the frozen churros in a single layer.
Air fry at 375°F (190°C) for 10–12 minutes or until golden brown, flipping halfway through.
In a shallow dish, whisk together the sugar and cinnamon for the coating.
While warm, toss the churros in the cinnamon-sugar mixture until fully coated.
Serve immediately with chocolate ganache or warmed nutella for dipping.
