6 slices bacon, diced
4 cups all-purpose flour
4 ounces shredded extra-sharp cheddar cheese
1/4 cup chopped fresh chives
4 teaspoons baking powder
1 1/2 teaspoons kosher salt
1 teaspoon baking soda
3/4 cup unsalted butter, frozen
1 3/4 cups buttermilk
Preheat oven to 450 degrees F. Line a baking sheet with parchment paper or a silicone baking mat.
Heat a large skillet over medium high heat. Add bacon and cook until brown and crispy, about 6-8 minutes. Drain excess fat; transfer bacon to a paper towel-lined plate.
In a large bowl, combine bacon, flour, cheese, chives, baking powder, salt and baking soda.
Grate butter using the large holes of a box grater. Stir into the flour mixture.
Add buttermilk and stir using a rubber spatula until a soft dough forms.
Working on a lightly floured surface, knead the dough 3-4 times until it comes together.
Using a rolling pin, roll the dough into a 1 1/4-inch thick rectangle. Cut out 10-12 rounds using a 2 1/2-inch biscuit or cookie cutter.
Place biscuits onto the prepared baking sheet; place in the freezer for 15 minutes.
Remove biscuits from freezer. Place into oven and bake for 15-18 minutes, or until golden brown.
