Heat a heavy-bottomed pan or a cast iron pan. Add butter and let it melt.
Add Maple syrup to the pan.
Next, add brown sugar.
Also, add Salt.
Combine everything and let the sugar melt. The caramel slowly starts to bubble up. Next, add cinnamon powder.
Mix everything. Stir and cook as the caramel bubbles up.
Next, add the pecans. Combine and let the caramel coat over all the pecans.
Cook on a low flame for 3 mins and switch off the flame.
Preheat an air fryer to 200 C / 400 F for 5 mins. Spread parchment paper in the air fryer basket. Transfer the pecans to the air fryer. Spread well and make sure the pecans don't touch each other.
Airfry at 356 F / 180 C for 7 mins. After 5 mins open the air fryer and shake the basket once.
Let the pecans cool completely. Break if there are any lumps. Cinnamon glazed Pecans are now ready.
