1 can refrigerated buttermilk biscuits
3 tablespoons melted butter
1/3 cup sugar

Preheat oven to 375 degrees. Separate the dough into 10 biscuits and flatten each into 2 ½-inch rounds. With a 1-inch biscuit cutter, cut a hole in the center of each biscuit round. Dip all surfaces of doughnuts (and holes) in melted butter, then in sugar. Bake 10-to-14 minutes until golden brown.
