In a mixer beat cream cheese on medium a few mins until smooth.
Add sour cream, heavy cream, vanilla, sugar , cornstarch and beat on low.
Once smooth, add eggs on low.
Pour into cooled crust. (I poured in half, added some jam and swirled it with a knife. Then I poured on the rest and swirled some more jam onto the top.)
Bake at 225 for 3 hours.
Shut oven off and leave cake inside 1 hour to cool.
Then, crack door open for another hour as it cools to room temp.
Remove and chill overnight.
