• Preheat your oven to 180°C/350℉ (fan forced).
• Grease a ring cake tin really well (with butter or coconut oil). In this pic I used a 25cm bundt tin. If your tin is old or not non-stick, you may want to add in baking paper tags to help to leaver it out of the tin.
• Bring a small pot of water to boil, turning it down to a low simmer. Place the chocolate, coconut milk and sweetener into a large stainless steel bowl and sit over the pot. Stir until the chocolate has melted and the ingredients are well combined. Remove from the heat and set aside, allow to cool to luke warm.
• Once it's cooled (enough so you can hold your finger in the mix (I know you want to lol), beat the eggs into the chocolate mixture and mix until well combined.
• Pour the mixture into your prepared, well greased ring tin. Place the tin in a deep roasting dish and pour hot water into the roasting dish until the water level is about half to two thirds the way up the sides of the ring tin. You are making a basic steam bath here and the moist air helps this cook through, whilst keeping it lovely and moist.
• If you happen to have a 'steam' oven, you can simply cook it in this (without the steam bath). 
• Bake for about 35-45 minutes or until the batter is set firm.
• Leave to cool at room temperature then store in the fridge overnight or until ready to serve.
• Once ready to serve, bring back to room temperature and remove from the tin by inverting onto a serving plate. If you have trouble removing, shake the tin and sit the tin in hot water for a minute to loosen it. I just jiggle/ tap it on the bench and sit in hot water until it releases (be patient, it can take a few tries). 
• Make a berry sauce by blending the fresh strawberries and/ or raspberries until smooth. You can strain the seeds from the coulis if you prefer a very smooth sauce (I personally don't bother). Put aside in a small serving jug (this can also be made ahead if you like). This sauce really helps cut through the richness of the cake.
• Now get creative and decorate the wreath with whipped cream, berries and mint. 
• Serve with the berry sauce in a side jug immediately (or return to the fridge again until ready to serve).
