Pre-heat oven to 350 degrees F
In a food processor blend together the dates, chia seeds (or eggs), honey and coconut oil. Add this mixture to all of the other ingredients and stir gently. Pour into a round cake pan that has been oiled and lined with grease proof paper.
Bake for 30-45 minutes until a skewer inserted into the centre comes out clean. Leave in the pan for 10 minutes, then turn out onto a cooling rack. This is a very dense cake which will not rise a lot.
Decorate with pineapple slices and shredded coconut, and icing if desired.
