Preheat oven to 425 degrees F.
In a large bowl, whisk together dry ingredients: flour, salt, baking powder.
Cut up or grate butter into small pieces and cut into flour using hands, fork, or pastry cutter. Butter pieces should be the size of peas.
Add milk and stir until a rough dough forms. Take care not to overmix.
Scrape biscuit dough onto countertop and use hands to form into a large rectangle.
Fold dough in half and smash four to five times. This creates the flaky layers.
Using hands, press dough out until it is about ¾ inch thick.
Using a round biscuit cutter or glass cut out 9 biscuits. Do not twist cutter. Cut straight down and bring straight back up.
Place cut biscuits on a parchment lined baking sheet and bake for 15 minutes or until beginning to get golden brown. If you over bake they may be dry so keep an eye on them.
