You can increase or decrease the sugar to your liking. You can go as much as 1 1/3 cups of sugar or decrease if you would like. Just try the mixture and add as you wish. You can also substitute a sweetener like Truvia(TM), Stevia, or Splenda(TM). I would go about half because they are much sweeter than sugar. So, start with half and add gradually until you get a flavor you like.
