Method
Preparation
In a medium saucepan, combine water, butter, sugar, and salt over medium heat until boiling.
Remove from heat and stir in flour until a dough forms.
Allow to cool slightly, then mix in eggs one at a time, followed by vanilla extract.
Preheat the air fryer to 375°F (190°C).
Using a piping bag, pipe small bites onto parchment paper.
Spray with cooking spray and air fry for 10-12 minutes until golden.
Coating and Serving
In a bowl, mix sugar and cinnamon.
Toss churro bites in the sugar mixture before serving.
Serve warm with dipping sauces like chocolate or caramel.
Notes
Do not overfill the air fryer basket. Cook in one layer. Let the dough cool a bit before adding eggs so the eggs do not cook. Shake the basket halfway through cooking for even browning.
