Preheat air fryer to 375 degrees.

Lay one sheet of puff pastry on a floured surface.

Using a pizza cutter, cut the puff pastry sheet in half lengthwise. Then cut 1/2 inch strips for a total of 18 strips.

Twist each strip and place in the air fryer basket in a single layer.

Air fry for about 8 minutes or until golden brown.

While churros are air frying, melt 1/4 cup of butter in the microwave for 20 seconds.

Once churros are done air frying, using a silicone pastry brush, brush melted butter over each churro and sprinkle with cinnamon sugar.

Enjoy with warm chocolate syrup!
