In a small bowl, mix together the milk and vinegar and set aside to “sour”.
Preheat the oven to 400˚F.
In a medium bowl, mix together the flours, baking powder, sugar, oats and raisins.
In a separate bowl, beat together the butter, egg and soured milk. Slowly mix in the flour mixture until fully incorporated.
Pour the batter onto a lightly sprayed 8-inch circular pan. Bake for around 15 minutes, or until the scones are golden brown.
