Why It Works

  • Sweet potato purée provides hydration while keeping the dough thick and easy to handle, and the biscuits light and moist.
  • Folding the dough creates layers and structure, for pull-apart biscuits sturdy enough for a breakfast sandwich.
  • Baking on cast iron ensures the biscuits are crisp along the bottom.

Thick and mellow sweet potato purée makes these colorful biscuits tender, moist, and light. Despite their vibrant color, sweet potato biscuits have a buttery flavor that's as classic as they come—perfect to serve alongside hearty soups and stews, or with a simple spoonful of blueberry jam.

Ingredients

  • 9 ounces all-purpose flour, such as Gold Medal (about 2 cups, spooned; 255g)
  • 1 tablespoon baking powder
  • 2 teaspoons (8g) Diamond Crystal kosher salt; for table salt, use about half as much by volume or the same weight Diamond Crystal kosher salt
  • 1/2 teaspoon baking soda
  • 4 ounces cold, unsalted butter, cut into 1/2" cubes (about 8 tablespoons; 110g)
  • 9 ounces sweet potato purée, from one large sweet potato, see note (about 1 heaping cup; 255g)
  • 3 ounces milk, any percentage will do (about 1/3 cup plus 1 tablespoon; 85g)

Directions

  1. Adjust oven rack to lower-middle position and preheat to 400°F. Should your kitchen be warmer than 75°F, please see our guide to baking in a hot kitchen before getting started; the specifics are focused on pie dough, but the overall principles are true of biscuits as well.

  2. Sift flour, baking powder, baking soda, and salt into a medium bowl, then whisk until well combined (this may take up to 1 minute). Add the butter, toss to break up the pieces, and smash each cube flat. Continue smashing and rubbing until the butter has mostly disappeared into a floury mix, although a few larger, Cheerio-sized pieces may remain. This can also be done with 4 or 5 pulses in a food processor, just take care not to overdo it. The prepared mix can be refrigerated up to 3 weeks in an airtight container, then used as directed below.

  3. Mash the sweet potato purée and milk together with a fork, or combine with an immersion blender until perfectly smooth. Add to the dry mix in a large bowl, and fold with a flexible spatula until fully absorbed. The dough will seem rather crumbly and dry at first, but keep mixing until it finally comes together. Once the dough forms a rough ball, turn out onto a lightly floured surface.

  4. With your bare hands, gently pat the dough into a squarish shape about 1/2-inch thick, then fold in half; repeat twice more for a total of 3 folds, using only enough flour to keep your hands from sticking. Finish by patting the dough to a thickness of 3/4 inch. If needed, dust away any excess flour, then cut into 1 3/4-inch rounds and arrange in a 10-inch cast iron skillet. Gather scraps into a ball, pat and fold a single time, then cut as many more biscuits as you can. The final round of scraps can be gathered and shaped into a single biscuit by hand.

  5. Bake until the biscuits are well-risen and golden brown, about 25 minutes (or longer if cut thicker than 3/4-inch). Let the biscuits cool about 5 minutes to help set their crumb, then serve as desired, whether alongside soups and stews or split for shortcake or breakfast sandwiches. Leftovers can be stored up to a week in an airtight container; to serve, split the stale biscuits in half, brush with melted butter, arrange on a baking sheet, and broil until golden brown, then serve with jam.

Special equipment

1 3/4-inch round cutter (or similar), 10-inch cast iron skillet

Notes

Prepare the purée by roasting or microwaving a large sweet potato until fork tender; discard the peel and mash the interior until smooth.
