Ingredients
Dry Ingredients
- 4 cups all-purpose flour
- 4 teaspoons baking powder
- 1 1/4 teaspoons kosher salt
- 1 teaspoon baking soda
Wet Ingredients
- 3/4 cup unsalted butter (frozen)
- 1 3/4 cups buttermilk
Instructions
- Preheat Oven: Preheat your oven to 450 degrees F and lightly oil a 10 1/2-inch square cast iron skillet or coat it with nonstick spray to prevent sticking.
- Combine Dry Ingredients: In a large bowl, stir together the all-purpose flour, baking powder, kosher salt, and baking soda until well mixed.
- Grate Butter: Using the large holes of a box grater, grate the frozen unsalted butter directly into the flour mixture. Stir to distribute the butter evenly through the dry ingredients.
- Add Buttermilk: Pour in the buttermilk and stir with a rubber spatula until a soft dough forms, being careful not to overmix.
- Knead and Roll Dough: Transfer the dough to a lightly floured surface and knead just 3-4 times until it comes together. Roll the dough into a 9-inch square, trim edges to form an 8-inch square, then cut into 9 or 12 equally sized square biscuits using a sharp knife.
- Arrange in Skillet: Place the cut biscuits evenly into the prepared cast iron skillet, leaving a little space between them so they can expand while baking.
- Bake Biscuits: Bake in the preheated oven for 16-19 minutes until the biscuits are golden brown on top and cooked through.
- Serve Warm: Remove the skillet from the oven and serve the biscuits warm for best flavor and texture.
Notes
- Using frozen butter grated into the flour helps create flakier layers in the biscuits.
- Do not over-knead the dough to keep the biscuits tender.
- Cast iron skillet helps achieve a crispy bottom crust and even baking.
- You can adjust baking time depending on your oven – start checking at 16 minutes.
- Serve these biscuits with butter, honey, or your favorite jam.
