Well, I figured this would happen when I posted about it back in May – Chocolate Mint is no more. We ran out of weeks and days this week, we have 40 of the samples left and then that’s it. I’ve already removed it from the “Sample all the things” (though we have a couple with it already in there so they’re getting a free bonus flavor). I’ve seen people try adding mint extract to Rich Chocolate but I haven’t personally tried it myself.
I personally use Torani Sugar Free Peppermint Syrup. “Torani Sugar Free Syrups are made with the finest ingredients including all-natural flavor, purified water and Splenda Brand Sweetener.” Pretty cheap on Amazon. Works great with Rich Chocolate!
