Copy Cat Cheddar Bay Biscuits

2 cups all-purpose flour
1 tablespoon sugar
1 tablespoon baking powder
2 teaspoons garlic powder
1/2 teaspoon kosher salt
1/4 teaspoon cayenne pepper, optional
1 cup buttermilk
1/2 cup unsalted butter, melted
1 1/2 cups shredded sharp cheddar cheese

FOR THE TOPPING
3 tablespoons unsalted butter, melted
1 tablespoon chopped fresh parsley leaves
1/2 teaspoon garlic powder

Preheat oven to 450 degrees F. Line a baking sheet with parchment paper or a silicone baking mat; set aside. In a large bowl, combine flour, sugar, baking powder, garlic powder, salt and cayenne pepper, if using. In a large glass measuring cup or another bowl, whisk together buttermilk and butter. Pour mixture over dry ingredients and stir using a rubber spatula just until moist. Gently fold in cheese. Using a 1/4-cup measuring cup, scoop the batter evenly onto the prepared baking sheet. Place into oven and bake for 10-12 minutes, or until golden brown. For the topping, whisk together butter, parsley and garlic powder in a small bowl. Working one at a time, brush the tops of the biscuits with the butter mixture. Serve immediately.
