Preheat air fryer to 300°F. Spray the bottom of your air fryer basket with nonstick baking spray.
In a small mixing bowl, whisk together egg whites and vanilla extract. In a large bowl, add almonds and pour over egg white mixture. Toss nuts to evenly coat.
In a small bowl, stir together sugars, salt and cinnamon. Sprinkle over nuts and use two spoons to evenly coat the nuts in the cinnamon-sugar mixture.
Spread out nuts evenly in a single layer in the air fryer basket.
Air fry the almonds for 8-10 minutes, tossing halfway.
Notes
To roast cinnamon almonds in the oven, bake at 250 degrees F on a rimmed baking sheet (in a single layer) for 60 minutes.
