Freeze 12 tablespoons unsalted butter until solid (at least 2 hours, ideally overnight). Preheat the oven to 400°F and line a baking sheet with parchment paper or a silicone mat.

In a large bowl, whisk together 3 cups of all-purpose flour, 2 1/2 teaspoons of baking powder, 2 teaspoons of sugar, 1 1/4 teaspoons of kosher salt, and 1/2 teaspoon of baking soda.

Grate the frozen butter on the large holes of a box grater directly into the flour mixture. Chop the remaining piece evenly and combine using a fork, breaking up any clusters of butter.

Gradually pour in 1 cup of buttermilk, tossing the mixture gently with a fork. Knead briefly to form a shaggy dough and transfer to a lightly floured surface. Pat into a 6-inch square, pressing any loose bits into the dough.

Cut the dough into 4 squares, stack, and roll into a 5x7-inch rectangle about 1-inch thick. Trim edges (optional) and cut into 6 squares. Place on prepared baking sheet, at least 2 inches apart. Freeze for 10 minutes.
