Sweet Potato and Black Pepper Biscuits

2 cups all-purpose flour

2 teaspoons baking powder

1 teaspoon white sugar

½ teaspoon ground black pepper

½ teaspoon baking soda

¼ teaspoon salt

¾ cup butter

1 cup cold mashed sweet potatoes

2 tablespoons heavy cream

Preheat oven to 425 degrees F (220 degrees C).

Whisk flour, baking powder, sugar, pepper, baking soda, and salt together in a large mixing bowl. Cut butter into the flour mixture with a pastry cutter or fork until the mixture resembles coarse crumbs. Stir sweet potatoes and cream into the flour mixture until the dough is soft.

Turn the dough out onto a lightly floured work surface; knead the dough, turning over about 5 times. Roll to about 1/2-inch thick. Cut 2-inch circles out of dough and arrange on a baking sheet.

Bake in preheated oven until lightly browned, 12 to 15 minutes.
