01 - Preheat the oven to 425°F. Line a baking sheet with parchment paper.
02 - Whisk together the flour, baking powder, baking soda, salt, dried herbs, and black pepper in a large bowl.
03 - Add the cold butter cubes and use a pastry cutter or fingertips to blend into the flour mixture until pea-sized crumbs form.
04 - Stir in the grated cheddar and chopped fresh herbs evenly.
05 - Make a well in the center, pour in the cold buttermilk, and gently mix until just combined without overworking the dough.
06 - Transfer dough to a lightly floured surface. Pat into a 1-inch thick rectangle, fold in half, turn, and repeat twice to create flaky layers.
07 - Cut out biscuits using a 2.5-inch round cutter. Arrange on the baking sheet touching for soft sides or spaced for crisp edges.
08 - Brush the biscuit tops with a beaten egg for a golden finish if desired.
09 - Bake for 13 to 15 minutes until golden brown. Allow to cool slightly before serving.
