Preheat the oven to 200°C, gas mark 6. Mix the flour, salt and baking powder in a bowl. Mix the butter with the garlic.
Rub the garlic butter into the dry mix to resemble breadcrumbs. Stir in the chives and cheese.
Gradually blend in the milk to give a soft dough. Roll out on a floured surface to 2cm thick. Using a 6cm round cutter, cut out 8 buns and place on a baking tray. Brush with milk and bake for 10 minutes until risen and golden.
