Beat the heavy cream until it holds soft peaks, not stiff ones. Set it aside.
In another bowl, beat the softened cream cheese by itself until it's really fluffy. Scrape down the sides of the bowl.
Beat the confectioners sugar into the cream cheese until it's smooth.
Add the whipped cream and mix well until it's one smooth mixture.
Gently fold in the cranberry sauce with a spatula. Spoon the dip into a bowl and serve it with fruit.
Notes
Make ahead: make it up to 1 day ahead and keep it covered in the fridge. If it settles, whip it for a few seconds to fluff it up again.Leftovers: keep covered in the fridge and eat within 1 day. Don't leave it out for more than 2 hours.Freezing: not recommended.Cranberry sauce: homemade is best. If you buy it, use whole berry cranberry sauce, not jellied.
