It’s unclear where the new Mac & Cheese Popcorn from Conagra Brands’ Act II will fall, but we’re willing to try it out as soon as humanly possible. How will the mac and cheese flavor differ from just cheese? There’s no indication of when we can expect to see the Mac & Cheese Popcorn in stores, but we’re keeping our fingers crossed that it’s this year, and soon. Believe it or not, this isn’t the first time Act II has added mac and cheese flavor to its popcorn. A few years ago, the brand released a ready-to-eat bagged Bacon Mac & Cheese Popcorn.
