-
Pour the caramel sauce into the bottom of the frozen crust and spread it out gently; it doesn’t have to reach the edge. Sprinkle the peanuts over that, then return the pan to the freezer.
-
Pour the sweetened condensed milk into a medium mixing bowl, add the vanilla, and stir to combine. Set aside.
-
Remove the large bowl and beaters from the fridge and beat the heavy cream on high speed until it holds stiff peaks. (You’re done beating when you can lift the beaters out of the whipped cream and the peaks don’t fold back in on themselves.)
-
Fold about a half cup of the whipped cream into the sweetened condensed milk to lighten, then gently fold in the rest of the whipped cream.
-
Fold in the chopped snickers and pour the filling into the frozen crust. Cover with plastic wrap and return to the freezer for at least 8 hours.
-
When you’re ready to serve, let the cake sit at room temp for a few minutes so it’s easier to slice.
-
Slice and serve with drizzles of caramel, chocolate, and sprinkles of chopped peanuts. Uneaten ice cream cake can be stored, tightly wrapped, for 3 months.
