Toast the pecans: In a dry skillet over medium heat, toast chopped pecans for 3–4 minutes, stirring, until fragrant. Let cool completely.
Cream the butter and sugars: In a mixing bowl, beat butter, granulated sugar, and brown sugar for 2–3 minutes until light and creamy.
Add wet ingredients: Beat in the egg, orange zest, orange juice, and vanilla until smooth.
Scrape the bowl.
Mix dry ingredients: In a separate bowl, whisk flour, baking soda, baking powder, salt, and cinnamon (if using).
Combine: Add dry ingredients to the wet mixture. Mix on low just until no streaks remain. Fold in cooled pecans.
Chill the dough: Cover and chill for at least 30 minutes.
This helps the cookies hold their shape in the air fryer.
Preheat the air fryer: If your model allows, preheat to 320°F (160°C) for 3 minutes. Line the basket with a perforated parchment liner or lightly mist with oil.
Portion the dough: Scoop 1 1/2-tablespoon balls (about 30–35 g each). Place in the basket with 2 inches of space between cookies.
Gently press to a thick disk. Sprinkle with coarse sugar if you like.
Air fry: Cook at 320°F (160°C) for 6–8 minutes until edges are golden and centers look just set. Every air fryer runs a bit different, so check at 6 minutes.
Rest: Let the cookies sit in the basket for 3–4 minutes to firm up, then transfer to a rack to cool.
Repeat with remaining dough.
