  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.
