1. Preheat oven to 450F / 230C.
2. Line a baking sheet with parchment paper, set aside.
3. In a large bowl, combine flour, sugar, baking powder, garlic powder, salt, and cayenne pepper, if using.
4. In a large glass measuring cup, whisk together buttermilk and melted butter.
5. Be quick, or the butter will set in the milk, if cold.
6. Pour mixture over dry ingredients and stir using a rubber spatula just until moist.
7. Gently fold in cheese.
8. Using a ¼-cup measuring cup, scoop the batter evenly onto the prepared baking sheet.
9. Place into oven and bake for 12-15 minutes or until golden brown.

Topping

1. Whisk together butter, parsley, and garlic powder in a small bowl.
2. Working one at a time, brush the tops of the biscuits with the butter mixture.
3. Serve immediately.

***Bakers note for a next time:

1. I will omit the cayenne pepper, as I am not a fan of it, but as this was an experiment, I used it.
2. I will use a little less cheese.
