Are Kit Kats gluten-free? No, the wafer is wheat

No. The wafer in a standard Kit Kat is made with wheat flour.

What the maker’s pages say

• US (Hershey): contains wheat, and Hershey’s own FAQ says Kit Kat is not gluten-free.
• UK (Nestlé): Nestlé’s UK FAQ says KitKats aren’t gluten-free. The one exception it names is the seasonal KitKat Bunny, which it calls gluten-free: look for the gluten-free wording on the pack. The UK KitKat Advent Calendar (85 g) has no page on Nestlé’s own site; on Morrisons’ product page, which carries Nestlé UK’s product data, its ingredients list rice flour and corn flour and no gluten cereal, but the page does not call it gluten-free (read 2 November 2026). See the advent calendars whose maker or shop says gluten free.
• Germany, Austria and Italy (Nestlé): the 208 g KitKat advent calendar is called gluten-free on the product pages of REWE, BILLA, BIPA and Esselunga, and their ingredient lists name rice flour and maize instead of wheat (read 2 November 2026). That is the calendar, not the KitKat bar: read the box you buy.
