No, this cookie is not safe if you have a hazelnut allergy. The product description explicitly states it contains hazelnuts. The chocolate-hazelnut paste is a key component of the flavor profile.
Additionally, the product contains milk, soy, and egg, which are other common allergens. Even if hazelnuts are not listed as a primary ingredient in every layer, they are present in the recipe. It is also important to consider that products like these are often manufactured in facilities that handle other nuts and allergens, so cross-contamination is a possibility. Always read the ingredient list and allergen information on the physical packaging before consumption, as formulations can change. If you have severe allergies, it is safest to avoid this product entirely.
