You just need a deep fryer and a tube of buttermilk biscuits to make these delicious, foolproof biscuit donuts! Pre-cut biscuit dough is the best secret weapon for perfectly round and perfect easy donuts. We love sprinkling our donuts with cinnamon, sugar, and powdered sugar, but you could also use store-bought frosting or glaze for an especially decadent twist. If you don’t have a deep fryer, you can also heat about 2 inches of oil over your stove in a large-bottomed pot over medium heat. Biscuit donuts are a great snack to make with kids on the weekend; they’ll love getting to cut out the donut shapes as much as they’ll love eating them!
