Preheat your air fryer to 320°F (160°C) for about 5 minutes while you prepare the cookie dough.
In a mixing bowl, sift together the flour, baking soda, baking powder, salt, and ground cinnamon. Set aside.
In another large bowl, use an electric mixer to cream together the softened butter, brown sugar, and granulated sugar until light and fluffy (about 2-3 minutes).
Beat in the egg and vanilla extract until fully incorporated.
Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. If desired, fold in the chopped nuts and chocolate chips.
Using a cookie scoop or a tablespoon, drop heaping spoonfuls of dough onto a piece of parchment paper, making sure to leave space between each cookie.
Carefully place the parchment paper with cookie drops into the air fryer basket. Depending on the size of your air fryer, you may need to cook in batches.
Cook the cookies in the air fryer for about 8-10 minutes or until the edges are golden brown. Keep an eye on them because cooking times may vary based on your air fryer model.
Remove the cookies from the air fryer and let them cool on a cooling rack for about 5 minutes before serving.
Serve warm and enjoy the delightful sweet cinnamon aroma that fills the kitchen!
Notes
Optional nuts and chocolate chips can be added for extra flavor.
