The classic Twix bar contains no gelatin and uses vegetable fats, so it is halal by its ingredients. However, like other Mars candy bars, it is not halal-certified in the United States. It also contains an emulsifier called E471, or mono- and diglycerides, and Mars does not say whether this comes from plants or animals. That unknown is why Twix cannot be certified. Mars does make halal-certified Twix for some Muslim-majority countries.

The short answer
Twix has no gelatin and uses vegetable fats. However, the source of one ingredient, called E471, is unknown, and the bar has no halal certificate in the United States. So Twix is halal by its ingredients with one caveat, but it is not certified.
Does Twix contain gelatin?
No. The classic Twix bar is made of a cookie, caramel and chocolate. It contains no gelatin, and it uses vegetable fats instead of animal fat. The gelatin problem that affects many gummy candies does not apply to Twix.
What is the problem with E471?
The one question is an emulsifier called E471, also known as mono- and diglycerides. An emulsifier is an ingredient that helps oil and water stay mixed. E471 can come from either plants or animals.
Mars does not say publicly whether the E471 in its US and UK Twix bars comes from plants or animals. Without that information, nobody can independently confirm that the bar is halal. This is the same issue that affects Snickers, and it is why we mark Twix as "depends."
Is Twix halal-certified anywhere?
Yes. Mars makes halal-certified Twix for some Muslim-majority countries. The standard bars sold in the United States and the UK are not certified.
