Mix dry ingredients and cut in cold butter cubes. Pinching with fingertips until the mixture resembled course breadcrumbs.
Slowly add in milk, incorporating until you have a soft dough, that is not too sticky.
On floured surface, roll dough out to approximately 1" thick. With the edge of a glass, cut 4 circles out and place them on parchment in the air fryer.
Bake at 390deg for 12 minutes or until lightly golden (or bake at 400 for 15-20 min, checking often)
Enjoy with a dollop of your favourite jam and yogurt!
