Sieve the flour, baking powder and caster sugar into mixing bowl.
Add the wheat bran.
Add the butter cubes to the mixing bowl and using your fingertips rub the butter into the flour mixture to form a breadcrumb mixture.
Gradually add the milk, mixing into the flour mixture to form a light elastic dough.
Roll out the dough on a lightly floured surface to about 1cm thick and then using a round 2"-3"/5cm - 7.5cm pastry cutter, cut out the scones one by one.
Place the scones on a lightly greased baking tray and brush the tops lightly with milk,
Bake in the oven for approximately 10 - 15 minutes. Check they are cooked before removing by inserting a skewer / toothpick into the middle of a scone, which should come out clean if they are ready.
Notes
*If you don't have self-raising flour mix together 225g plain flour and 1 tbsp. baking powder as a substitute.To make gluten free scones, substitute the plain flour here for gluten free flour.
