When a chocolate chip cookie say I need semi sweet chocolate chips , does it specificly need to say..?

You can use whatever kind of chips you want, be it semi-sweet, milk chocolate, peanut butter, etc. Just remember, if you use milk chocolate or dark chocolate it will not taste exactly the same as semi-sweet. The differences are sugar and milk fat. Most chocolate chip cookie recipes use semi-sweet.

If the recipe calls for semi-sweet chips and you want to use white chocolate or milk chocolate chips, that's fine. You don't have to use the semi-sweet chocolate chips. If you wanted to use semi-sweet chocolate chips, then of course the words "Semi-sweet" would HAVE to be on the package. How else could people find semi-sweet chocolate chips?

Only get the ones that say semi-sweet if you want to use semi-sweet chips.

Usually you can use any kind or flavor of chips in chocolate chip cookies. I almost always use the semi sweet because they are the kind I like.'

It doesn't matter at all infact, you could even mix different chips!
