Dietary & Allergen
Traditional toffee is made from sugar and butter, so it is naturally gluten-free but not dairy-free or vegan, and plain versions are usually nut-free unless nuts are added. The most common allergen concerns are dairy from butter, nuts as toppings or cross-contact, and soy from some chocolate coatings, so labels should always be checked for added ingredients.
Gluten, Dairy, and Nuts
Classic toffee contains no wheat, so it is generally gluten-free, but butter makes standard toffee unsuitable for dairy-free or vegan diets. Dairy-free versions can be made with plant-based butters or oils, though flavor and texture will differ.
Reading Labels
Chocolate coatings may contain milk and soy lecithin, and shared equipment can introduce nut or gluten cross-contact. Anyone with a serious allergy should look for clear allergen statements and, where needed, dedicated allergen-free production.
