Prepare. Preheat your oven to 425. Also, prep a baking sheet with parchment paper.
Dry Ingredients. In a large mixing bowl, use a whisk to combine together your flour, parsley, baking powder and soda, chili powder, and garlic powder.
Butter. Next, use a pastry cutter to cut the cold butter into your dry ingredients. If you do not have a pastry cutter you can try using two forks or a food processor. When you are done cutting the butter into the dry ingredients there should be pea sized pieces of butter in the dough.
Wet Ingredients. Use a rubber spatula or similar item to mix in your buttermilk and then the beaten eggs until just about combined. Then use the spatula to fold in your cheddar cheese.
Biscuits. To form the biscuits first transfer your dough to a clean workspace that has been lightly dusted with flour. Then use a rolling pin to roll out the biscuits to about ¾ inch thick. Use a cookie cutter (2 ½ to 3") to cut out the biscuits and then place the biscuits about an inch apart on your baking sheet.
Topping. For the topping, use a fork or a whisk to combine together the melted butter with the parsley and garlic butter. Then use a pastry brush to brush it over your biscuits.
Bake. Bake the biscuits for 12-14 minutes or until the begin to brown. Then let them sit on the baking sheet for 10 minutes before transferring.
