Step 1

Preheat the air fryer to 200°C (400F).

Step 2

Place the flour, baking powder, and cold cubed butter into a large mixing bowl and rub in with your hands until you get a breadcrumb consistency.

Step 3

Mix in the caster sugar.

Step 4

Heat the milk in the microwave for 30 seconds then add a squeeze of lemon juice and the vanilla extract. Leave to stand for 2 minutes then using a cutlery knife, mix the soured milk into the flour.

Step 5

Bring the dough together with your hands. The dough will be quite sticky and soft at this stage.

Step 6

Lightly flour your work surface then shape the scone dough into a round disc (roughly 3cm thick) using your hands. Using a 5cm fluted cookie cutter, stamp out 5 scones. You'll need to keep reforming the dough into a disc with your hands until you have used it all up.

Step 7

Glaze the tops of the scones with a little milk, and then air fry for 7-8 minutes until golden brown and well risen.

Step 8

Remove the scones from the air fryer basket and cool them on a wire rack for 10 minutes before serving.
