In a large mixing bowl, combine flour, sugar, baking powder, and salt.

Add the cold butter to the dry ingredients and use your fingers or a pastry cutter to work it into the mixture until it resembles coarse crumbs.

In a separate bowl, lightly beat together the milk/cream and egg.

Pour the wet ingredients into the dry mixture and gently mix until just combined.

If adding any optional add-ins, fold them in now.

On a floured surface, shape the dough into a circle about 1 inch thick.

Cut the circle into 4 equal triangles to form scones.

Place the scones on a plate or tray lined with parchment paper and chill in the fridge for at least 15 minutes.

Preheat your air fryer to 375°F while the scones are chilling.

Once chilled, place the scones in the air fryer basket, leaving space between them for air circulation.

Cook for 8 minutes, or until golden brown and cooked through.

Remove from the air fryer and let them cool for a few minutes before serving.
