Let cool completely before topping.
To make the topping, in a large bowl, combine pudding mix, milk, heavy cream, and vanilla. Whisk until the mixture just begins to thicken.
Spread pudding mixture over the cooled cake and refrigerate for at least 1 hour and up to 4 hours until cold or until ready to bake.
Heat broiler.
Sprinkle sugar all over the surface of the pudding layer as evenly as possible.
Broil for about 2 minutes the cake until the sugar starts to turn golden. Watch very carefully as this can happen fast. Serve immediately
