About Magnum Billionaire

Magnum Billionaire matches the rest of the Magnum range at £2.75 in city and London stores, the same price as Magnum Classic and Magnum White. No calorie or nutrition figures have been recorded for it here, which is fairly common for the ice cream section compared with the baked treats around it, where fuller breakdowns tend to be available. Allergen data isn't listed either, so it's worth checking the wrapper or asking in-store if that matters to you. At this price, it sits well above most of the doughnuts, cakes and biscuits on the wider menu, reflecting the premium that ice cream treats generally carry over baked ones here.
