Chocolate Cake (with bananas, optional)

I made this cake for my birthday last week, and my raw friends found it really delicious. I like it too, because I love the combination of bananas and chocolate. If you do not like bananas, you do not have to include them.

While making the cake, you can enjoy the "leftovers" as delicious raw drinks: The water from the 2 young coconuts, as well as the soaking water from the dates which is nice and sweet.

BTW, what is the difference between a blender and a food processor?
