Warm the chocolate chips in a small glass dish in the microwave for 20-30 seconds at 50% power. Stir until smooth. Place the popcorn in a single layer on a piece of wax paper or parchment paper on a plate. Drizzle with the melted chocolate. Place in the refrigerator until firm, at least 20-30 minutes.
Scoop the vanilla ice cream into a serving bowl.
Top the ice cream with the chocolate-drizzled caramel popcorn.
Drizzle with hot fudge and caramel sauce if using.
Finish with whipped topping and serve immediately.
Notes
For a fun twist, you can mix crushed chocolate-drizzled popcorn directly into the ice cream before scooping. Recipe can be multiplied to serve more guests.
