In a large bowl, stir together the self-rising flour and baking powder. Pour in melted lard and mix until blended. Stir in buttermilk and milk just until the dough comes together.
Pat dough out on a lightly floured surface and roll to ¾-inch thickness. Cut into biscuits using a biscuit cutter or round cookie cutter. Place on baking sheets, spacing about 1 inch apart. Brush the tops with bacon drippings.
Bake for 10 to 12 minutes in preheated oven, until the bottoms and tops are lightly browned.
