1. Combine half-and-half, popcorn, and vanilla bean in a large pot over medium heat and heat until starting to bubble. Reduce heat to low and simmer, stirring occasionally, 5 minutes. Remove from heat and allow to cool.
2. Once cool, remove vanilla bean and discard. Pour mixture into blender container and pulse until well combined. Pour through a fine mesh strainer, pressing to extract liquid from popcorn pieces. Discard solids. Cover and chill popcorn milk in fridge 8 hours, or overnight.
3. Add popcorn milk and ice cream to blender container and blend until smooth. Pour buttery popcorn milkshake into serving glasses and top with whipped cream and popcorn, if desired.
