Preheat oven to 450°F.
In a medium bowl, add flour, baking powder, sugar, and salt. Whisk ingredients to combine.
Pour in 2 cups cold buttermilk. Stir just until combined. Be careful not to over mix it.
Pour the melted butter into an 8x8 inch baking pan. Pour the dough on top of the butter. Evenly spread the batter into the pan.
Using a knife, pre-cut 9 squares into the unbaked batter.
Bake for 25 minutes, or until the tops are golden and the biscuits are baked through.
Allow the biscuits to cool for a few minutes before serving. Enjoy!
