How to Make Mashed Potato Biscuits
These biscuits are super easy to make with only a few simple ingredients. Using a box grater, grate half of a stick of butter. Place grated butter into the freezer to keep it super cold. In a large bowl, whisk together flour, salt, and baking powder. Add the chilled butter and toss to coat. Add leftover mashed potatoes and gently toss with a fork until the mashed potatoes are pea-sized. Gently stir in grated cheese. Make a well in the center of the mixture. Pour buttermilk into the well and stir just until a dough forms.
Place the dough on a lightly floured surface. Gently pat, knead, and roll the dough to about a 10-inch circle. Cut the dough with a 3-inch biscuit cutter. Rerolling dough scraps as needed. Place biscuits on a baking sheet lined with parchment paper. Brush the tops of the biscuits with buttermilk and sprinkle with fresh cracked black pepper. Sprinkle with more grated cheese. Bake in a preheated oven until golden brown.
