Creating Crispy Air Fryer Churro Bites is an effortless process that follows these straightforward steps:

1. Prepare the Batter: In a medium saucepan, bring the water, butter, sugar, and salt to a simmer over medium heat.
2. Add Flour: Once simmering, add the flour all at once. Stir continuously until the mixture forms a ball and pulls away from the sides of the pan. Remove from heat.
3. Incorporate Eggs: Let the mixture cool for about 5 minutes. Then, add the eggs one at a time, mixing well after each addition until fully incorporated. Stir in the vanilla extract and baking powder until smooth.
4. Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C).
5. Prepare the Air Fryer Basket: Lightly spray the air fryer basket with cooking spray to prevent sticking.
6. Pipe the Bites: Transfer the churro dough to a piping bag fitted with a large star tip. Pipe the dough into bite-sized pieces directly into the air fryer basket, leaving space between each for even cooking.
7. Air Fry: Cook the churro bites for approximately 10-12 minutes, or until they are golden brown and crispy.
8. Make Cinnamon Sugar: While the churro bites cook, combine the granulated sugar and cinnamon in a small bowl.
9. Coat the Bites: Once cooked, remove the churro bites from the air fryer and immediately toss them in the cinnamon sugar mixture until well coated.

With these steps, you will have perfectly crispy churro bites ready in no time!
