In a large mixing bowl combine flour, baking powder, sugar, 2 teaspoons garlic powder and salt. Mix until combined. Add 1/2 cup cold butter and mix with pastry cutter or fork. You don't want to mix to thoroughly there should be small chunks of butter about the size of a pea in there. Add cheddar cheese and milk and mix just until combined.
Drop 1/4 cup size biscuits (I like to use an ice cream scoop) onto the baking sheet. Bake for 12-14 minutes or until golden brown.
Meanwhile melt the other 3 tablespoons butter in the microwave for 30 seconds add 1/2 teaspoon garlic powder, Old Bay seasoning and chopped parsley.
Remove biscuits from oven and brush with butter. Enjoy!
