Making crispy air fryer churro bites is straightforward if you follow these easy steps:

1. Prepare the Air Fryer: Preheat your air fryer to 375°F (190°C) while you prepare the churro dough.
2. Combine Dry Ingredients: In a mixing bowl, whisk together the flour, granulated sugar, salt, and baking powder until well combined.
3. Cook the Mixture: In a saucepan, bring the water and butter to a boil over medium heat. Once boiling, remove from heat and quickly stir in the dry ingredients until a dough forms.
4. Incorporate Eggs: Let the dough cool for a couple of minutes, then add the eggs and vanilla extract to the mixture, stirring until smooth.
5. Shape the Churro Bites: Transfer the dough to a piping bag fitted with a star tip. Pipe small bite-sized pieces (about 1-2 inches long) onto a piece of parchment paper.
6. Coat with Cinnamon Sugar: In a separate shallow dish, mix 1/4 cup sugar with the cinnamon. Once you’ve piped the churro dough, coat the bites generously in the cinnamon sugar mixture.
7. Air Fry the Bites: Spray your air fryer basket with cooking spray. Place the churro bites in a single layer (you may need to do this in batches) and air fry for about 10-12 minutes, or until they are golden and crispy.
8. Cool Slightly: Carefully remove the churro bites from the air fryer and let them cool for a few minutes.
9. Serve: Once slightly cooled, consider giving them an additional sprinkle of cinnamon sugar for an extra layer of flavor.

By following these straightforward steps, you’ll have a delightful batch of crispy air fryer churro bites ready to enjoy!
