Preheat air fryer to 300°F and spray a baking pan with nonstick spray.
Whisk flour, remaining 2 tsp sugar, baking powder, baking soda and salt and in a bowl; add butter and using clean hands or a pastry cutter mix, break butter into small pieces.
Slowly pour in buttermilk and mix until dough comes together; it will be sticky!
Transfer to prepared baking pan; spread out and press down in an even layer.
Cook for 15 minutes or until golden brown on top and cooked through.
Allow to cool for 10 minutes, then serve with strawberries and a dollop of whipped cream.
