• Freeze the butter for at least 20 minutes to create a flaky texture.
• Preheat the oven to 425°F and line a baking sheet with parchment paper.
• In a large bowl, whisk together the flour, baking powder, sugar, and salt.
• Grate the frozen butter and mix it into the dry ingredients with a fork.
• Pour the milk or buttermilk into the mixture and stir until a dough forms.

Folding and Cutting

• Turn the dough onto a floured surface and pat into a 1½-inch thick rectangle, then fold in half.
• Repeat the folding process 4 to 6 times to create layers.
• Press the dough to a 1-inch thickness and cut out biscuits without twisting.

Baking

• Place the biscuits on the prepared baking sheet and optionally brush the tops with milk or melted butter.
• Bake for 13 to 16 minutes until lightly golden brown.
