Buzzball still good?

Okay so I’m 23, I don’t ever drink so I’m kinda clueless on the topic of it but I’m STRESSED and going through it and I have one of those creamy chocolate buzzballs in my fridge but thing is, it’s been there for at least a year and a half, maybe more. so I’m just wondering if it’s still okay to drink? like do they go bad? It’s sealed still. I feel like this is a stupid question but yeah
