Once the butter, sugar, and salt are fully incorporated mix in flour and remove from heat
Let the mixture rest for 5-10 minutes or until it is room temperature
Add vanilla and eggs to the flour, butter, salt, and sugar mixture
Mix with your hands until it is smooth
How To Pipe The Churros
Carefully cut a hole in the tip of the piping bag just large enough for the piping tip to stick through, without being able to push the entire tip through the end.
Use a silicone spatula to place the churro batter into the piping bag.
Place parchment paper the same size as your air fryer basket on a baking sheet.
Carefully pipe 3-4 inch churros onto the parchment paper.
Let the piped churros chill in the refrigerator for 45 minutes to an hour (check out the trick for faster chilling below).
How To Air Fry The Churro Batter
Carefully lift and place the parchment paper with the batter inside your air fryer basket.
Lightly spray the churros with oil
Air Fry at 375F for 4-5 minutes
Half way through the cooking cycle, flip the churros over, spray the other side with cooking oil and cook for an additional 4-5 minutes
When the air fryer churros are done cooking, spray them again with oil and toss in the cinnamon-sugar blend.
