Preheat your air fryer to 300 degrees F (150°C) for about 5 minutes.
In a large bowl, combine the oats, nuts, seeds, and coconut flakes. Add the cinnamon or nutmeg and mix well.
Drizzle the honey or maple syrup and vanilla extract over the oat mixture. Stir until all the ingredients are evenly coated.
Spread the mixture in an even layer in the air fryer basket or tray. Make sure not to overcrowd the basket; you may need to cook in batches depending on the size of your air fryer.
Air fry at 300°F (150°C) for 10-15 minutes, stirring every 5 minutes to ensure even cooking. Keep an eye on it to prevent burning.
Once the muesli is golden and crispy, remove it from the air fryer and let it cool completely. After it has cooled, mix in the dried fruits.
Store your homemade muesli in an airtight container. Enjoy it with milk, yogurt, or as a topping for smoothie bowls.
