Step 1

Preheat oven to 450 degrees Fahrenheit (232 °C). Coat a 10-inch cast-iron skillet with about a tablespoon of butter and set aside.

Step 2

To a large mixing bowl, add flour, baking powder, baking soda, salt, sugar, black pepper, sun-dried tomatoes, basil, chives, and cheddar cheese. Mix with a wooden spoon to combine all the ingredients.

Step 3

Add butter and use fingers or a pastry cutter to cut the butter into the flour mixture until it resembles pea-sized crumbs. If using fingers, roll lumps of butter in between the thumb and index finger to break into smaller pieces.

Step 4

Add butter and use fingers or a pastry cutter to cut the butter into the flour mixture until it resembles pea-sized crumbs. If using fingers, roll lumps of butter in between the thumb and index finger to break into smaller pieces.

Step 5

Add buttermilk to the flour mixture and use a wooden spoon to mix the dough until all of the flour is moistened and the dough starts to hold together. Do not overmix the dough. Turn dough out onto a lightly floured surface and form into about a 3/4-inch thick disc.

Step 6

Use a biscuit cutter or the rim of a glass to cut out 8 biscuits. Reroll the dough as needed to get more biscuits. Place biscuits close together in the cast-iron skillet and brush the tops generously with melted butter.

Step 7

Bake biscuits in the preheated oven for 18-20 minutes, until the tops are golden brown. Brush the tops of the hot biscuits with more melted butter after removing them from the oven. Serve biscuits warm. Enjoy!
