Preheat the oven to 400 degrees F. Line a large baking sheet with parchment paper.
In a large bowl whisk together the flour, baking powder, salt and black pepper.
Use a pastry blender or 2 knives used scissor fashion to cut in the butter until small pea-sized crumbs form.
Mix in the Parmesan.
Add the buttermilk and heavy cream. Stir until just combined - don't overmix - it will be thick.
Scoop up the batter with ⅓ cup measure and pat it into a round about 1 + ¼ -inch thick. Place on the baking sheet an inch or two apart.
Bake 20 - 22 minutes until lightly golden.
In a small bowl combine the melted butter with the black pepper and brush it over the hot biscuits. Repeat until it's all used up.
They're best served warm.
