Preheat oven to 425° Fahrenheit. Line baking sheet with parchment paper and set aside.
In large bowl, combine flour, baking powder and salt in a large bowl. Mix well, then set aside.
Remove chilled butter from freezer. Grate into small pieces, then mix into flour mixture.
Add milk to flour mixture. Stir until just combined, being careful not to over-mix.
Transfer biscuit dough to a floured surface. Using your hands, work mixture into a dough. If dough is too sticky, add small amounts of flour until workable, but try to add as little as possible.
Once dough is formed, gently fold dough into itself and knead approximately 10 times. Form into a soft ball.
Using your hands, flatten dough to 1" thick. Use a 2" biscuit cutter to cut dough into discs. Place discs on baking sheet, approximately ½" apart.
Repeat until out of dough, kneading and flatting as needed until all dough has been formed into discs.
Bake for 12 minutes, then remove from oven.
