The initial appeal of this recipe was its simplicity and the fact that it called for low-fat margarine and skim milk. In addition, as my husband is a diabetic, I substitued granular Splenda for the sugar - just followed the online Splenda info source (www.splenda.com) to add 1/2 tsp. of extra baking powder for every cup of Splenda used instead of sugar, and checked for earlier cooking time. It turned out really well, except that the outcome was a little "paler' than it would have been with real sugar. I suppose I can always sprinkle some sugar on top to add some color.
Also I added a tsp. of ground cinammon and vanilla as suggested by earlier reviewers. I will definitely make it again.
