Allan, one province of the delectable Kingdom of the realNaranja is famous for its ‘vlaai’, a flat cake in the form of a pizza with sweet toppings like apricot, cherries, whipped cream, apple crumble etc.
In Limburg everybody is very proud of this pastry. So two bakery academies assigned a team of pupils with the task to bake a record ‘vlaai’. I am sure it will fit your criteria perfectly.
It is 5.1 meters wide and weighs 400 kg. The topping is apricot. Must be enough to completely overwhelm the BC-in-C. You could even wrap him into it and listen to the noises inside, or draw the maps of Trumpworld on it and give him a pointer and a few military vehicles to play war on it. An absolutely killing treat.
