Twix bars are NOT gluten free. They contain wheat flour as a primary ingredient in the cookie base, making them unsafe for people with celiac disease or gluten sensitivity. Mars, the manufacturer, also does not label Twix as gluten free, and the bars are produced in facilities that handle wheat.

Twix Ingredients Breakdown
The classic Twix bar contains the following key ingredients:
- Enriched wheat flour — the primary gluten source
- Sugar
- Palm oil
- Skim milk
- Cocoa butter
- Chocolate
- Corn syrup
- Dextrose
- Salt
- Soy lecithin
The first major ingredient after sugar is enriched wheat flour, which contains gluten. There is no version of a standard Twix bar that substitutes this for a gluten-free flour alternative.
Why Twix Is Not Gluten Free
Twix gets its signature crunch from a shortbread-style cookie base, and that cookie is made with wheat flour. Gluten is a protein found in wheat, barley, and rye — and it’s essential to how that biscuit layer holds together. Without wheat flour, Twix would lose its defining texture entirely.
Mars does not offer a certified gluten-free version of Twix in the United States. If you have celiac disease or non-celiac gluten sensitivity, Twix in any of its standard forms should be avoided.
What About Twix Varieties?
None of the main Twix product lines are gluten free:
| Variety | Gluten Free? | Reason |
|---|---|---|
| Twix Original | ❌ No | Wheat flour in cookie layer |
| Twix Dark Chocolate | ❌ No | Wheat flour in cookie layer |
| Twix White Chocolate | ❌ No | Wheat flour in cookie layer |
| Twix Peanut Butter | ❌ No | Wheat flour in cookie layer |
| Twix Ice Cream Bar | ❌ No | Contains cookie crumbles with gluten |
The cookie component is the same across all varieties — they all start with wheat flour, so none of them qualify as gluten free.
Gluten Free Chocolate Bar Alternatives
If you love the combination of chocolate, caramel, and crunch but need to stay gluten free, here are some options to explore:
- Snickers — Gluten free per Mars (no wheat-based components)
- Reese’s Peanut Butter Cups — Generally considered gluten free (check label)

Cross-Contamination Risk
Even if a product’s ingredient list doesn’t include wheat, cross-contamination can be a serious concern for people with celiac disease. Mars manufactures Twix in facilities that process wheat — meaning even trace amounts could end up in adjacent products on the same production line.
Always look for a certified gluten-free label if cross-contamination is a concern for you. A product that doesn’t list wheat as an ingredient but isn’t certified may still pose a risk.
