In a medium bowl, combine boiling water, lime jell-o powder & lime juice; mix & let partially set. In a large bowl, cream cheese & sugar together; set aside. Using package directions, make Dream Whip (place in fridge until ready to use). Once jell-o is partially set, pour into cream cheese/sugar mixture (if using 1/2 & 1/2 cream add at this point) & beat to combine. If using Dream Whip, with a rubber spatula, fold into jell-o, cream cheese/sugar mixture. Evenly divide among the 12 mini cheesecake pan cups. Cover with plastic wrap & refrigerate for at least 2-3 hours before topping with glaze.
