Slice the avocados in half, remove the pits, and scoop the flesh into a blender or food processor.

Add cocoa powder, maple syrup, almond milk, vanilla extract, and salt to the blender.

Blend until the mixture is smooth and creamy, scraping down the sides as necessary.

Taste and adjust sweetness if needed, blending again briefly.

Transfer the mousse into serving glasses or bowls, and chill in the refrigerator for at least 1 hour before serving.
