There is no mainstream gluten-free Kit Kat, so the brand should be avoided. The wafer is the gluten source, not the chocolate.
For a gluten-free crispy chocolate option, look at brands that make GF wafer or crisped-rice chocolate bars, or stick to plain gluten-free chocolate.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
