Sweet Potato Biscuits

Steps

• Prep: Heat the oven to 200°C (400°F) and line a baking sheet.
• Dough: Whisk the flour, baking powder, salt, and cinnamon together, then cut in the cold butter until it looks like coarse crumbs.
• Dough: Whisk the cooled sweet potato purée and buttermilk together, then stir into the flour mixture just until it comes together.

  Tip: The purée must be fully cooled — warm purée will melt the cold butter you just worked in, and this dough depends on that butter staying solid.

• Shape: Turn onto a floured surface, pat to 3/4 inch thick, and cut rounds, pressing straight down without twisting.
• Bake: Arrange on the sheet and bake until golden — check a couple of minutes early, since the sugar in the sweet potato browns faster than a plain biscuit.
