Preheat oven to 425°F.

In a large mixing bowl, whisk together flour, baking powder, and salt.

Add butter and cut in with a pastry blender until pea-size clumps form.

Create a well in the center of the mixture by pushing the mixture toward the sides of the bowl. Pour buttermilk into the well. Mix gently with a fork until JUST combined. (Over mixing will make tough biscuits!)

Turn the dough out onto a floured surface and create a rectangle using your hands.

Fold the dough into thirds (like folding a letter). (Fold left side over center, then right side, so it's still in a rectangular shape.) Then roll back out to 1-inch thick. Repeat the folding and rolling process twice more, Rolling the dough out to ½" thick on the final time.

Cut out about 12 biscuits with a 2 ½"-3" cutter. Re-roll any scraps until there's about 10-12 biscuits.

Transfer biscuits to a baking sheet so that the biscuits are touching each other and the edge.

Bake at 425° for about 13-15 minutes until cooked through and golden brown on top.
