Preheat oven to 450 degrees F.
Line a large baking sheet with parchment paper.
In a large mixing bowl, whisk together the flour and other dry ingredients until well combined.
Cut in the cold butter cubes until the butter is only small pieces. If you do not have a pastry cutter a fork will work.
Pour the cold buttermilk into the mixture and gently stir it until a dough starts to form.
Place the dough onto a lightly floured surface and gently work together with your hands until all ingredients are mixed. You do not need to use a rolling pin. Pat the dough flat and fold it in thirds. Repeat this process two more times.
Pat the dough into a thick rectangle (about 1/2 inch thick). Using a floured 2 1/2 inch biscuit cutter, cut out the biscuits in the dough.
Continue gathering scraps and patting it back down and cutting until you have 8-12 biscuits. Try to cut as many as you can the first time so as not to overwork the dough.
Place biscuits on baking sheet so that they are touching each other. Brush a little buttermilk on the top of each biscuit.
Bake at 450 degrees for about 15 - 17 minutes or until lightly golden brown on top. Remove from the oven and allow to cool for 1 - 2 minutes. Enjoy!
