A physicist has used the power of artificial intelligence (AI) to solve the age-old debate about whether Jaffa Cakes are biscuits or cakes. Dr. Héloïse Stevance, an astrophysicist at the University of Auckland in New Zealand, trained algorithms with nearly 100 recipes of traditional cakes and biscuits. She then ran two Jaffa Cakes recipes through the algorithms, which recognised them unambiguously as cakes'without a doubt'. Jaffa Cakes, which are made by Edinburgh-based manufacturer McVitie's, consist of a disc of orange-flavoured jelly, milk chocolate and a mysterious spongy base. But fans of the popular British snack have passionately debated whether they're biscuits or cakes due to their unique texture and appearance.

Before Brexit, one of the greatest causes of arguments amongst British families was the question of the nature of Jaffa Cakes. Some argue that their size and host environment (the biscuit aisle) should make them a biscuit in their own right. Others consider that their physical properties (e.g. they harden rather than soften on becoming stale) suggest that they are in fact cake. In order to finally put this debate to rest, we re-purpose technologies used to classify transient events. We train two classifiers (a Random Forest and a Support Vector Machine) on 100 recipes of traditional cakes and biscuits. Our classifiers have 95 percent and 91 percent accuracy respectively. Finally we feed two Jaffa Cake recipes to the algorithms and find that Jaffa Cakes are, without a doubt, cakes. Finally, we suggest a new theory as to why some believe Jaffa Cakes are biscuits.
