Chocolate cake is so good.
Oh that sounds amazing!  I love chocolate.  Do you know much about it's origins?
It was first made in 1886 by American cooks who added chocolate to their cake batter
So it was initiall a sweet treat from the beginning?
Yes. In the late 1800s, chocolate recipes were mostly for chocolate drinks, and in cakes it was only used in fillings and glazes.
Where is it grown, do you know?
The earliest evidence of chocolate (or cacao) is in Mexico
Interesting indeed  - I would have thought Cuba
