In a bowl, mix the self-raising flour, sugar and baking powder together.

Using your hands, rub in the chilled butter until it turns into breadcrumbs.

Add the raisins to the breadcrumb mixture and mix until they are evenly dispersed.

In a separate bowl mix the egg, milk and vanilla essence.

Add the wet ingredients and mix until a wet dough forms. It will be sticky so use a spoon.

Line the air fryer basket with baking paper.

Use two spoons and scoop dollops onto the baking paper. Scoop a large spoonful with one spoon and use the second spoon to help scrape it all off.

Air fry for 160°C 12 to 15 minutes. You may need to air fry in batches. The first batch I made took 15 minutes and the second batch took 12 minutes as the air fryer was already hot. As with all air fryer recipes keep an eye on the rock cakes when you air fry them for the first time and adjust your cooking time if needed.
