To a saucepan over medium heat bring the milk to a gentle simmer, but do not boil.
In a mixing bowl whisk together the egg yolks & sugar. Slowly temper in the milk to the egg yolks. Add the mixture back to the saucepan & continue cooking until the milk slightly thickens, about 4 minutes.
Transfer the mixing back to the mixing bowl. Whisk in the cream cheese, heavy cream, vanilla & salt until fully incorporated. Run mixture through a fine mesh strainer & chill overnight.
Once the mixture has been fully chilled, transfer to an ice cream maker & churn for 30 minutes.
Add half the churned ice cream to a loaf & half the raspberry sauce. Swirl raspberry sauce into the ice cream using an offset spatula & repeat.
Finish with a sprinkle of graham cracker crumbs if desired. Transfer to the freezer & let chill for a minimum of 4 hours.
