Preheat oven to 450 degrees F. Line a baking sheet with parchment paper or a silicone baking mat.

In a large bowl, combine flour, Parmesan, baking powder, pepper, salt and baking soda.

Grate butter using the large holes of a box grater. Stir into the flour mixture.

Add buttermilk and stir using a rubber spatula until a soft dough forms.

Working on a lightly floured surface, knead the dough 3-4 times until it comes together. Using a rolling pin, roll the dough into a 1 1/4-inch thick rectangle. Using a sharp knife, cut 2-inch square biscuits, or use a 2-inch biscuit or cookie cutter. Place biscuits onto the prepared baking sheet; place in the freezer for 15 minutes.

Remove biscuits from freezer. Place into oven and bake for 15-18 minutes, or until golden brown.

Serve warm.
