One of my favourite desserts, and I eat it often, is just with sugar free jello and whipped cream. (LIME is the best!!!!)
Make one package of sugar free jello as normal and let it set in a bowl. Mix another package of the same flavour with only 1 cup of boiling water. Put it in the fridge until it is cold and just setting. Whip one cup of whipping cream till firm, then add the partially set jello into it. Then put the cream mixture on top of the already set jello, nad put it int he dridge for ½ hour. Presto!!!! Great dessert!!!
