Sift flour, sugar, baking powder, baking soda, salt, and cinnamon in a medium mixing bowl.
Cut cold butter into small chunks (½ tablespoon-size pieces) and add to the dry ingredients.
Use a pastry blender or two forks to cut the butter into the flour mixture until the butter is broken down into pea-size pieces.
Add buttermilk and stir to combine into a rough mixture.
Add the raisins into the scone mixture and stir or knead very lightly to distribute the raisins throughout the mixture.
Turn dough out onto a lightly floured surface and divide in half.
Form each dough half into a circle and pat out until it is only ¾” thick.
Score the dough lightly into wedges and lift carefully into the greased basket of the air fryer.
Cook in the air fryer at 350°F for 15 minutes or until the scone is cooked all the way through.
Whisk together glaze ingredients, adjusting the amount of cream until desired consistency is reached.
Drizzle glaze over scones and allow to set.
Plate, serve, and enjoy!
