Preheat oven to 450 degrees Fahrenheit.

In a medium bowl, whisk together the flour, baking powder, sugar, and salt.

Add the buttermilk and stir until the batter is mixed. Be careful not to over-mix. The batter will be thick, and it is OK if it has a few small lumps.

Melt the butter in a microwave safe dish and pour the melted butter into an 8 x 8 baking dish.

Pour the dough gently into the baking dish on top of the butter. Using a spatula, spread the dough out to the corners of the baking dish.

Again, using the spatula, deeply score the dough making 9 equal-sized squares (in a 3 x 3 pattern).

Bake in a preheated oven for 25 to 28 minutes. The tops of the biscuits should be golden brown.

Remove from oven and allow the biscuits to rest for 5 to 7 minutes to allow the butter to be absorbed.

Cut and serve warm. (No butter required for these biscuits!)
