Preheat the oven for 180 degrees Celsius.
Soak chia seeds in 1 cup of water until all water is absorbed.
While they are soaking, blend the cacao melts till fine, then add the banana to be blended as well (or you can mash the banana by hand). If you have a large blender, you can keep adding all the ingredients into the blender, or transfer the ingredients into a large bowl.
Combine all ingredients and blend or hand mix until well combined.
Line the cake tin with extra coconut oil or butter to prevent it from sticking, and pour the mix in. Bake in the oven for 35-45 minutes.
Take out of the oven and let it sit for about 5-10 minutes, smother with the icing/mousse and enjoy like this, or serve with seasonal fruit and dusted with extra cinnamon.
