Heat oven to 300° F
Beat the cream cheese and 1 cup brown sugar on medium speed until smooth.
Add eggs, one at a time, just until blended.
Add 3/4 cup heavy cream until blended. Pour this over the cold crust.
Bake at 300°F 70-80 minutes until edge of cheesecake is set at least 2 inches from edge of pan. Middle will still wiggle a bit.
Turn off the oven and open the door a bit. Let cheesecake sit there for 30 minutes.
Cool on a rack for another 30 minutes.
Chill in fridge a few hours.
