Splenda = 24g per cup, so 2 cups would be 48g ... Divided by 12, that adds another 4g per serving.

More carbs for any icing of course ... Most commercial cream cheeses, such as Philadelphia, have 1 g per Tbsp (½ oz)

This sounds really yummy, and suitably rich .... but definitely an infrequent treat. Would be good for Maintenance.
