Check process shots in the post for visual) Now divide into 8 biscuits. Place them to the baking sheet 1-inch apart.
Bake the biscuits. Brush biscuits with little milk, place pan in the oven and bake the biscuits. Tops should be golden brown once done. They'll need to bake for 15-20 minutes of time.
