If using fresh pineapple, remove the core, dice into chunks, and freeze until solid.
Add frozen pineapple, pineapple juice, lemon juice, vanilla, and ice cream to a blender.
Blend until smooth and creamy, stopping to stir if needed.
Scoop into cups or pipe through a decorating bag for the classic swirl look.
Serve immediately and enjoy! 🍍🍦
