FIRST, set your oven to 450 degrees.
You can always melt your butter on the stove top or microwave. I just put it in my 9 inch cake pan and melt it on the stove on low. Keep an eye on it so it doesn't burn or brown.
While the oven is preheating and the butter is melting, combine your dry ingredients in a large mixing bowl.
Next, add the buttermilk and mix all of the ingredients together until a moist dough is formed.
Check on your butter occasionally. It's probably melted by now.
Spread dough right on top of the melted butter and use an offset spatula to spread it evenly across the pan making sure the dough touches the sides.
Cut the unbaked buttery dough into wedges. This dough is very wet, just do the best you can, and let the butter seep into the crevices.
Place in oven and bake for 20-25 minutes or until golden brown.
Remove from oven and let cool slightly. Serve biscuits nice and hot.
