This is a childhood favorite reinvented for grown-up tastes. You've got the texture of a Fudgsicle but with the flavor of rich dark chocolate, salty peanuts, and sweet caramel, all combined in a dessert pretty enough to make people think it came out of a professional kitchen.
It's important that the Fudgsicle bars soften at room temperature for 5 minutes before serving, otherwise they'll be too hard to cut into. The flavor comes forward when the dessert warms a little. Don't forgo the ice-water bath. You need to cool the custard quickly to keep it from overcooking.
