I actually like these dairy free cornettos.
Tried them in NZ, can recommend.
"Water, sucrose, vegetable oil, glucose syrup, glucose-fructose syrup, corn flour, maize starch, roasted hazelnuts, soybean powder (1.4%), cocoa powder, emulsifiers (471, 322, 442), vegetable gums (410, 412, 407 (contains dextrose from wheat)), salt, flavour."
The wafer doesn't appear to be made of wheat, so there's small amounts of gluten in the cornettto. Depends how sensitive you are to wheat, but it isn't triggering an adverse reaction for me. YMMV.
