CAKE For the cake: combine the sugars and the cinnamon in a plastic bag. Break the biscuits into quarters and add 10 or 12 pieces at a time to the bag and shake to coat. Place in a greased tube or bundt pan. For the sauce: Melt the butter and sugars in a small saucepan. Cook until thick. Pour over the biscuits and bake at 350 degrees for 30 minutes.
