A Belgian chocolate tea cake

Broken version. Costa at Wetherby services offer these - chocolate covered marshmallow with a jam centre. A bit rich. The bloke in front got this one. I tried to persuade him to seek a reduction using the logic that as he was in Yorkshire then he should do as the locals do and get a bargain due to its broken shell. Living in Yorkshire for 30 years does this to you.

Unfortunately he was from Sussex.
