Preheat the oven to 450°F. Line a baking sheet with parchment paper.
In a medium bowl use a whisk to sift together biscuit mix, garlic powder, parsley flakes and onion powder.
Make a well in the center and add the buttermilk and 1/2 of the melted butter. Mix with a fork just until moistened. Stir in the shredded cheddar cheese.
Use a 4 ounce ice cream scoop to divide the dough into rounds. Place approximately 2 inches apart to allow for spreading while baking.
Mix 1/4 teaspoon of garlic powder and 1/4 teaspoon dried parsley flakes with the remaining butter. Brush the tops of the biscuits. Reserve a small amount to brush the tops after baking.
Bake for 12-15 minutes or until golden.
Brush the tops with garlic butter. Serve immediately.
