I have seen people make a cake out of watermelon, then add other fruits. Maybe an icing made with dates and carob powder??
Freelee has a video on youtube of a Banana Torte that was super yummy, you could easily add cacao powder to it if you choose as well ^~^
If it doesn't has to be raw, there are tons of high carbs low fat recipes out there (just google). I bet if you would google "low fat raw desserts" you could also find something. However I have never tried one.
Freelee once made a "banana apple date strudel". I made it and it was super delicious!
I saw a chocolate cake made with nut and chocolate powder and avocadoes. It was raw, let me try to find it. It was made with agave, walnuts, raw cocoa, and avocadoes....
Well I found THESE
Can't find it ._.
HOLD ON NOW!
Let it load.... stupid internet -_-
Did you want raw or cooked vegan?
