In a medium bowl, stir together the biscuit mix, milk, and Cheddar cheese; don’t overmix.
Drop by large spoonfuls onto an ungreased cookie sheet, or a cookie sheet lined with a silicone baking mat.
Bake for about 10 minutes, or until the biscuits are golden on top and baked completely.
In the meantime, in a small saucepan over low heat, melt the butter; add the garlic powder, parsley, salt, and pepper, and gently stir to mix.
Remove the biscuits from the oven, and while they are still on the baking sheet, immediately brush the tops of the biscuits generously with the melted butter mixture.
