Cake is SO many calories and so not worth it, maybe have a freddo or curly wurly, or plan to have one, that way you know you're going to get a treat. And make sure you don't sniff the cake.
Sniffing the cake leads to eating the cake (I know from experience
)
It looks lovely, but I had some cake last week and a normal slice for me was about 350-400 calories, and that was just plain sponge, wouldn't want to see the content of that cake..
