Begin by creaming the butter and granulated sugar until light and fluffy.

Gradually mix in the all-purpose flour, baking powder, cream of tartar, baking powder, kosher salt, egg, and vanilla extract until a smooth dough forms.

Fold half of the sprinkles into the cookie dough by hand, then pour the remaining sprinkles into a small bowl for topping.

Lightly spray the air fryer basket or tray with olive oil spray, or line with parchment paper.

Shape the dough into small rounds, dip each one into the remaining sprinkles, and place them onto the prepared basket or tray.

Set air fryer temperature to 320 degrees F and set cook time for 4-6 minutes.

Allow them to firm up as they cool, plate the finished cookies, and continue air frying the remaining dough.
