Preheat the oven to 425 degrees F. Line a cookie sheet with parchment paper and set aside.
In a large bowl combine flour, baking powder, sugar and salt. Mix until combined and set aside.
Remove butter from the freezer. Cut butter into flour mixture using a pastry cutter. A box grater can also be used to shred the butter into small pieces and then add to the flour mixture. Cut in butter until the mixture resembles coarse crumbs that are about pea size.
Add milk to the flour mixture. Stir the mixture with a wooden spoon or spatula until just combined.
Generously flour a surface and transfer the biscuit dough to the floured surface. Using your hands gently work the dough together and knead 10-15 times. Add more flour if the dough is too sticky until you can easily work with the dough.
Fold dough over itself and gently flatten layers together using your hands. Rotate 90 degrees and repeat folding about 5-6 times. Be careful not to overwork dough.
After folding 5-6 times pat the dough to ¾’’ - 1’’ thickness. Lightly dust a 2 ¾’’ round biscuit cutter with flour.
Gently press the biscuit cutter straight into dough and drop the biscuit on the prepared baking sheet. Repeat until all the dough is used, making close cuts.
With the leftover dough gently rework into ¾’’ - 1’’ thickness and cut more biscuits out. You should have at least 6 biscuits at the end.
Place biscuits in a preheated oven at 425 degrees F. Bake for 12 minutes or until the tops are beginning to turn golden brown.
Brush with salted butter immediately after removing from the oven if desired.
