Buuuut … there's a catch.

Attention, McDonald's lovers! The Twix McFlurry is BACK.

This news brings to mind an old saying: If you love something, let it go. If it comes back, it was meant to be. And this, my friends, was clearly meant to be.

There is one teensy tiny little thing getting in the way of our reunion: It's only returning in the U.K., according to Delish.

The flavor was only available to American customers for a limited time in 2015, but that hasn't stopped it from making a lasting impact.

McDonald's describes it as "soft dairy ice cream swirled with Twix chocolate-coated biscuit pieces and chocolate caramel sauce."

Needless to say, people like them. They like them a lot.

It's available in two sizes—mini and regular—and costs 99p or £1.39 (about $1.30 to $1.82 USD).

Here's one more catch: They won't be around forever. So if you find yourself in the U.K. before March 19, be sure to snag one of these little cups of heaven.
