Preheat oven to 400 degrees F. Lightly coat a baking sheet with nonstick spray.

In a small bowl, whisk together butter, Parmesan, garlic powder, parsley and salt; set aside.

Cut each biscuit in half, making 16 pieces. Roll each piece into a 5-inch rope, that are about 1/2-inch thick, and tie into a knot, tucking the ends.

Place knots onto the prepared baking sheet and brush each knot butter mixture, reserving half for after baking.

Place into oven and bake until golden brown, about 8-10 minutes.

Serve immediately, brushed with remaining butter mixture.
