Preheat your oven to 400 degrees Fahrenheit.
In a large bowl, combine the flour, salt, sugar, baking soda and baking powder.
Add the ice cold butter and cut it in using a pastry blender or knife. Blend in the butter until you get pea sized pieces. This will take a couple of minutes.
Create a well in the center of the flour mixture and add the butter milk. Fold in the flour to incorporate the mixture. You can use a spatula or your hands. I prefer using my hands.
Once the dough has come together, pour it out onto a floured surface. Roll out the dough into a uniform height, about 3/4 inch tall. Then using a floured biscuit cutter cut into 12 biscuits. You will have to re-roll the dough to get all 12 biscuits.
Place the biscuits onto a parchment lined cookie sheet and bake for 18-22 minutes or until golden brown. Let the biscuits cool on the sheet for 1 minute before removing to a cooling rack.
These biscuits are great slathered in butter or even as a breakfast sandwich.
