Preheat your oven to 400°F. Line a large baking pan with parchment paper and set it aside. In a large bowl, whisk together the flour, baking powder, parsley, salt and garlic powder. Then use a fork or pastry cutter to cut in the frozen, grated butter until it resembles small peas.

Fold in the buttermilk, then the shredded cheese until just combined. Careful not to overmix the batter or your biscuits will be dense. Use either a medium sized cookie scoop or two large spoons to drop the batter onto the baking pan, keeping an inch or two of space between them, as they will expand a bit in the oven.
