Preheat the oven to 425°F and line a cookie sheet with parchment paper.
Mix dry ingredients: In a small mixing bowl, stir together the flour, sugar, baking powder, and salt until well combined.
Shred butter: Remove the butter from the refrigerator and immediately shred the cold butter into the flour mixture. Stir to combine.
Form dough: Add the milk to the mixture and combine until a shaggy dough forms. Turn the dough out onto a floured surface and gently flatten it with a rolling pin until it's 3/4" thick.
Laminate the dough: Fold the dough in half over itself, then flatten to 3/4" thickness. Turn the dough 90 degrees, fold in half again, and flatten to 3/4" thickness. Repeat this step two more times.
Cut biscuits: Using a biscuit cutter, press straight down into the dough as close to the edge as possible and lift back up. Place the cut biscuits approximately 1/2" apart on the prepared baking sheet. Repeat this step until you've cut as many biscuits as you can.
Rework remaining dough: Gently rework the remaining dough, roll out to 3/4" thickness, and continue cutting biscuits until all the dough is used. This step should yield an additional two to three biscuits.
Bake: Bake the biscuits at 425°F for 12-15 minutes, or until the tops are golden brown.
