Combine the chia, flax, cocoa powder, sweetener, and salt in a bowl.

Add the coconut milk along with 1 cup of water to a pan and bring to a simmer. Add the chia seed mixture and reduce the heat to low-moderate, stirring continuously.

Cook for about 4-5 minutes until the mixture thickens and the liquid has cooked out. Stir in the chocolate extract and serve warm.

Sprinkle on a little more sweetener and a dollop of butter.
