Add 1 cup water to medium saucepan and bring to simmer over low heat. Place double-boiler or glass bowl on top of saucepan, making sure bottom of bowl doesn't touch water. Add chocolate to bowl and stir occasionally until chocolate is completely melted.
Transfer melted chocolate to blender and add remaining mousse ingredients. Blend until mixture is very smooth, scraping down sides of blender as needed to ensure smooth texture.
Transfer mixture to serving cups or bowls. Serve immediately as avocado chocolate pudding, or refrigerate at least 2 hours to allow mixture to thicken to mousse consistency. When ready to serve, garnish with dark chocolate, sprigs of mint, crushed raspberries, or whipped coconut cream.
Recipe Notes
You can also melt the chocolate in the microwave in 30 second bursts at 50% power, stirring well between each burst. Be very careful not to overheat or burn the chocolate, regardless of your melting method.
Chocolate: I HIGHLY recommend using melted chocolate. I haven't tried this recipe with chocolate powder and can't say for sure what adjustments would need to be made.
Maple Syrup: Use slightly less than ½ cup maple syrup if you're using coconut aminos instead of soy sauce. Coconut aminos are sweeter than soy sauce so you don't want to make the mousse too sweet.
Balsamic Vinegar:Don't sub any other vinegar here! And I highly encourage you to use a good, high-quality balsamic.
