Begin by preheating your air fryer to 325°F (165°C). While it's warming up, you can prepare the crescent rolls.

In a microwave-safe bowl, melt the butter. This usually takes about 20-30 seconds in the microwave. Set aside.

In a separate bowl, combine the granulated sugar and ground cinnamon. Mix them thoroughly until you have a uniform cinnamon-sugar blend.

Carefully unroll the crescent roll dough on a clean, flat surface. Separate it into the triangular sections.

Brush each triangle lightly with the melted butter. After that, sprinkle a generous amount of the cinnamon-sugar mix on top.

Start from the wider end of the triangle and roll the dough towards the pointed end. This will give you the classic crescent shape.

Gently place the prepared crescent rolls in the air fryer basket. Ensure they are spaced out and not touching, as they'll expand a bit during the cooking process.

Cook the crescent rolls in the air fryer for about 8-10 minutes or until they are golden brown and fully cooked through. Check halfway through and turn them if necessary to ensure even cooking.

Once done, remove the crescent rolls from the air fryer and let them cool on a wire rack for a few minutes. If you've prepared icing, drizzle it over the top while the rolls are still warm.

Serve your Cinnamon Crescent Rolls warm and enjoy the delightful combination of buttery, flaky pastry with the aromatic warmth of cinnamon.
