Preheat your oven to 450°F. Line the bottom of an 8 or 9-inch pan with parchment paper.
Place the flour, baking powder, and salt into a food processor and pulse to combine.
2 cups all-purpose flour, 1 tablespoon baking powder, ½ teaspoon salt
Add the cubed butter and pulse just until the flour mixture resembles coarse cornmeal.
8 tablespoons unsalted butter
With the food processor still running, slowly drizzle in just enough buttermilk to make the dough come together.
½ cup buttermilk
Transfer the dough to a lightly floured surface, and pat it into a 1-inch thick rectangle. Sprinkle ¼ of the shredded cheddar cheese over the dough.
¾ cup shredded cheddar cheese
Fold the dough in half so the cheese is on the inside. Pat it down again so it's about 1-inch thick. Sprinkle another ¼ of the cheese over the dough and repeat the process. Continue until all the cheese has been used.
Use a 3-inch biscuit cutter to cut biscuits out of the dough. Do not twist as you cut. Gather any scraps, pat them down, and cut out more biscuits.
Place the biscuits on the prepared pan and bake for 12-14 minutes or until the biscuits are golden brown.
