Step 1: Prepare Your Workspace Start by lining a large rimmed baking sheet with parchment paper or a silicone baking mat. This ensures the chocolate does not stick to the pan and makes cleanup a breeze. Spread your popped popcorn and broken mini pretzels evenly across the prepared sheet, removing any unpopped kernels as you go.
Step 2: Melt the White Chocolate In a microwave-safe bowl, heat the white chocolate chips in 30-second intervals, stirring well between each session. Once the chocolate is mostly melted and smooth, stir in the alcohol-free vanilla extract and the sea salt. Be careful not to overheat the chocolate, as white chocolate can seize easily if it gets too hot.
Step 3: Coat the Popcorn Using a spoon or a whisk, drizzle the melted white chocolate mixture back and forth over the popcorn and pretzels on the baking sheet. Use a rubber spatula to gently toss the mixture until everything is lightly and evenly coated with the sweet chocolate.
Step 4: Add the Festive Sprinkles While the chocolate is still wet, immediately shower the tray with the red and green festive sprinkles. You want to do this quickly so the sprinkles adhere to the chocolate before it sets. Feel free to add more or less depending on how colorful you want your Christmas Funfetti Popcorn to look.
Step 5: Let it Set Allow the popcorn to sit at room temperature for about 20 to 30 minutes until the chocolate has hardened completely. If you are in a hurry, you can pop the baking sheet into the refrigerator for 5 to 10 minutes. Once set, gently break the popcorn into clumps and serve.
