Preparation Steps

• Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper.
• In a large bowl, whisk together the flour, baking powder, baking soda, salt, and sugar.
• Cut the cold butter into the flour mixture using a pastry cutter or your fingers until it resembles coarse crumbs.
• Stir in the mashed sweet potato until evenly combined.
• Slowly pour in the cold buttermilk and stir just until the dough comes together; do not overmix.
• Turn the dough out onto a floured surface and gently pat into a 1-inch thick rectangle. Fold the dough over itself 2-3 times to create layers.
• Pat dough back to about 1 inch thick and cut into 8 biscuits using a round cutter.
• Place biscuits on prepared baking sheet and bake for 15-20 minutes or until golden brown.
• Remove from oven and allow to cool slightly before serving warm.
