Worlds healthiest cake

That is probably the healthiest cake that you can imagine...
This must not be baked and not a gram of sugar is added! :)

Ingredients:
1 watermelon, 250g lowfat curd, 100g Greek yogurt, 1 teaspoon vanilla, 1 small handful of roasted chopped almonds, various berries and fruits to decorate

Recipe:

There's no easier way to make a healthy cake :)
First you give time lowfat curd and yoghurt in a small bowl.
Add the vanilla extract and mix everything to a nice and smooth cream.

From the melon you cut off a thick piece from the upper and lower part.
So that the melon can stand upright.
Cut down the skin with a large sharp knife. Until the melon has a cylindrical shape.
Please do not throw away the cut off parts. Make a delicious smoothie out of it or just snack it!

Place the melon on a plate or an other dish with a flat underground.
Spread the yogurt cream on it and flatten it smooth with a knife.

So... Now you can be imaginative... Take everything on berries and fruits that you have and decorate the cake! :)
