Blend all ingredients until they form a solid mass in the food processor (it should be very fine with the occasional chunk).
Place mass on a plate and shape into a cake shape. You can use a mold if you want to. Have fun with the shape! You can use the end of a spoon or a chopstick to make nice fluted edges if you want. Wet the spoon if it starts to stick.
If the dates are very firm or dry, let them soak in a little purified water for about 15 minutes to soften. Discard any excess water.
Blend all ingredients until smooth and creamy, then frost the cake.
Decorate with lemon zest, nuts, fresh berries or passionfruit pulp.
