Preheat the oven to 425°F. Line a sheet pan with parchment paper or a sill pat.
In a large bowl, whisk together 2 cups of flour, 2 teaspoons of baking powder, 1/2 teaspoon of baking soda, 1/2 teaspoon of garlic powder, and 3/4 teaspoon of salt.
Add the 2 cups of cheese and toss to combine until the cheese is evenly coated with the flour mixture. Sometimes the easiest way is to just get in there with your hands!
Now add 1 cup of buttermilk and 6 tablespoons of melted butter. Stir just until combined. Remember not to over-mix. The batter is going to be a little lumpy, but it will all work out in the end I promise.
Use a 1/4-cup measure or an ice cream scoop, to loosely form the dough and drop it onto the prepared baking sheet. Space the unbaked biscuits about 1-2 inches apart.
Bake for 12-14 minutes until the biscuits are golden brown. Bake time can vary from oven to oven so just keep an eye on them and adjust baking time accordingly.
While the biscuits are baking, combine 4 tablespoons of melted butter, 1/2 teaspoon of garlic powder, and 1/2 teaspoon crushed parsley flakes in a small bowl.
As soon as they come out of the oven, use a pastry brush, to evenly apply the butter mixture to the tops of the biscuits.
Serve warm!
