Whisk flour, baking powder, salt, and sugar together. Cut in cold butter until the mixture resembles coarse meal.
Add warm water and stir until a soft dough forms. Knead briefly on a floured surface until smooth.
Roll dough to ¼-inch thickness and cut into 3-inch squares or triangles.
Lightly spray both sides with cooking spray and arrange in a single layer in the air fryer basket.
Air fry at 370°F for 8–10 minutes, flipping halfway, until puffed and golden brown.
Drizzle immediately with honey and sprinkle with cinnamon sugar.
Tip: The dough needs to be rolled thin enough to puff up dramatically in the air fryer. Make sure the air fryer is fully preheated.
