01 - Melt the dark chocolate in a heatproof bowl set over a saucepan of simmering water (double boiler method), stirring until smooth. Remove from heat and let cool slightly.
02 - In a food processor or blender, combine the avocados, melted chocolate, cocoa powder, maple syrup, vanilla extract, and sea salt.
03 - Blend until completely smooth and creamy, scraping down the sides as needed. If the mousse is too thick, add almond milk one tablespoon at a time until desired consistency is reached.
04 - Taste and adjust sweetness if necessary by adding more maple syrup.
05 - Spoon the mousse into serving glasses or bowls. Refrigerate for at least 1 hour to chill and set.
06 - Before serving, top each mousse with fresh raspberries. Garnish with grated dark chocolate or mint leaves if desired.
