Preheat your oven to 425°F and line a baking sheet with parchment paper.
In a large mixing bowl, whisk together the all-purpose flour, baking powder, garlic powder, and salt. Cut the cold butter into the dry ingredients using a pastry blender until the mixture resembles small crumbs. Gently fold in the shredded cheese.
Pour in the cold buttermilk, stirring just until everything is combined. Drop the dough onto the prepared baking sheet in roughly 1/4-cup portions.
Bake the biscuits for about 15 minutes, or until they turn golden brown.
As the biscuits bake, mix together the melted butter, parsley, and garlic powder. Once out of the oven, brush the tops of the warm biscuits with the garlic butter. Enjoy these cheesy delights while they’re still warm!
