• Using a food chopper or knife, chop the butter. Place butter in the refrigerator until ready to use.
• Preheat oven to 350 degrees. Place bacon in a heavy-duty casserole dish and bake for 30 minutes, or until crispy. Drain bacon and chop into pieces. Raise oven temperature to 450 degrees and preheat for the biscuits.
• In a large bowl, stir together flour, brown sugar, baking powder, and salt until fully incorporated.
• Using CLEAN hands, quickly mix the cold butter into the dough. DO NOT OVER BLEND or it will soften the butter (COLD is KEY). Add in cooled bacon pieces.
• Add buttermilk, slowly, and stir dough until uniformly moistened. You may need to add more buttermilk if dough is too dry. DO NOT USE TOO MUCH. Dough should be a tad crumbly.
• On a lightly floured surface, bring the dough and crumbs together and roll (or pat with your hands) to approximately 3/4-inch thickness.
• Cut out biscuits and place in a cast iron skillet or baking sheet lined with parchment. Bake for 11 to 15 minutes, or until tops are a light golden brown.

Optional Topping:

• Brush finished biscuits with 2 tablespoons melted butter heated with 1 tablespoon brown sugar.
