The greatest McFlurry of all time is BACK on the McDonald's menu.

When you know, you know. And if you don't know, get yourself informed ASAP. Because the greatest McFlurry of all time is back on the McDonald's menu in both the mini and standard size and it calls for a celebration. like, I'll be honest, I'd never really pick up a Twix chocolate bar but... there's something about those crunchy chocolate balls with Twix's signature caramel sauce all blended into McDonald's ice-cream that sends me to heaven on the first bite.
