1. Grease a bundt pan with butter or nonstick spray. Line with plastic wrap if desired for easier removal.

2. In a large saucepan over medium heat, melt the unsalted butter. Add mini marshmallows and stir until smooth.

3. Stir in the vanilla extract once the marshmallows are fully melted.

4. Place the popcorn in a large bowl. Pour the melted mixture over the popcorn and toss gently until coated.

5. Quickly mix in M&M’s, peanut butter cups, and sprinkles. Stir carefully to avoid melting the candies.

6. Press the mixture into the prepared bundt pan using buttered hands or a spoon.

7. Let set for 1 hour at room temp or 30 minutes chilled. Invert onto a plate to release.

8. Drizzle melted white chocolate over the top and decorate with more candies or sprinkles.
