Step 1

Preheat oven to 450 degrees F. Line a baking sheet with parchment paper or a silicone baking mat.

Step 2

In a large bowl, combine flour, baking powder, salt and baking soda.

Step 3

Add cold butter, using your fingers to work the butter into the dry ingredients until it resembles coarse crumbs.

Step 4

Add buttermilk and stir using a rubber spatula until a soft dough forms.

Step 5

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.

Step 6

Place biscuits onto the prepared baking sheet; place in the freezer for 15 minutes.

Step 7

Remove biscuits from freezer and brush tops with butter. Place into oven and bake for 15-18 minutes, or until golden brown.

Step 8

Serve warm.
