Preheat oven to 450 degrees F. Line a baking sheet with parchment paper - set aside.
In a large bowl, combine flour, sugar, baking powder, garlic powder, salt & chili powder.
In a large glass measuring cup, combine buttermilk & butter - whisk to combine.
Pour into dry mixture & stir using a rubber spatula just until moist.
Fold in cheese.
Scoop the batter evenly onto the prepared baking sheet. (You can use a 1/4-cup measuring cup for even distribution)
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 & then brush over the tops of the baked biscuits.
