Is it possible to have chocolate chunks in ice cream that aren't waxy? My wife loves mint / chocolate chip ice cream. It hasn't been my favorite because of how waxy the cocoa butter in the chocolate becomes when it is cold.

Is there a type of chocolate that won't become waxy when it is frozen?

Alternatively is there a good intensely chocolatey, chunky, ingredient that can be mixed into ice cream? And in particular, mint ice cream.

I'm wondering about solid ingredients not syrups.
I use dark chocolate chips (Whole Foods brand, vegan) when I make my own ice cream, and have not encountered any waxy texture. I can vouch for that but you can probably experiment with your favorite chocolate chips.

Somewhat OT but making mint ice cream isn't too hard if you have an ice cream maker, just follow the instructions for vanilla but use mint extract instead. Then add the chips when the ice cream is about 5 minutes away from being finished in the ice cream maker.
