The classic Twix bar contains no gelatin and uses vegetable fats, so it is halal by ingredient — but like other Mars bars it is not halal-certified in the US, and its emulsifier E471 (mono- and diglycerides) is from a source Mars does not disclose, which could be plant or animal. That undisclosed emulsifier is why certification is not available. Mars makes halal-certified Twix for some Muslim-majority markets.
HalalVouch presents evidence and does not issue religious rulings — you decide.
The short version
No gelatin and vegetable fats, but an undisclosed E471 source and no US certificate — so Twix is "halal by ingredient with a caveat," not certified.
Gelatin — not an issue
The classic Twix bar (biscuit, caramel and chocolate) contains no gelatin and uses vegetable fats rather than animal fat, so the gummy-candy gelatin concern does not apply here.
The E471 catch
As with Snickers, the sticking point is the emulsifier E471 (mono- and diglycerides). Mars does not publicly disclose whether its US and UK E471 is plant or animal-derived, and without that information the bar cannot be independently verified as halal — which keeps it at "depends."
Certified elsewhere
Mars produces halal-certified Twix for some Muslim-majority markets. The standard US and UK bars are uncertified.
