Corn on the cob is a ZeroPoint Food on Weight Watchers. So is salt. So all you're getting your points from is the butter. One tablespoon (three teaspoons) of stick butter is 5 points. So, measure your butter and use about half a teaspoon of butter per corn on the cob half and each piece is only 1 Weight Watchers Freestyle Point. If you're on the myWW Blue, Green, or Purple plans, be sure to consult your WW app and double check the points before adding this to your day.
