Step 1

Place the flour in a large bowl. Use your fingertips to rub the butter into the flour until it resembles fine breadcrumbs. Make a well in the centre and pour in the milk. Use a flat-bladed knife to stir until the dough just comes together.

Step 2

Turn the dough out onto a lightly floured surface. Bring the dough together and gently knead until just smooth. Press dough out to a 2cm-thick disc. Use a 6.5cm round cutter to cut 9 rounds from the dough, cutting the scones as close together as possible (see note).

Step 3

Line the base of an air fryer basket with baking paper, trimming to just fit. Use a small knife to cut a few holes in the paper so the air can circulate. Place the scones, just touching, on the paper and brush tops lightly with extra milk.

Step 4

Cook on 180C for 10 minutes or until scones have risen and turned golden brown. Stop the air fryer and open the drawer. Combine the cheese and bacon and sprinkle over the scones.

Step 5

Cook for a further 5 minutes or until the cheese has melted and bacon is crispy.
