I would not buy mini snickers because snickers are available all over Europe, so they would be nothing particular. I have never seen 3 Musketeers and I am not exactly sure what it is.
I think in Europe a product that is sold as chocolate has to have a certain percentage of cocoa butter, which is more expensive in production. Probably that is why the taste of chocolate is different.
What about peanut butter cups, or something else based on peanut butter? That is something not easily available there.
Anyway, I do not think you have to worry about customs.
