Slice the avocados in half and scrape out all of the flesh. Place in a food processor and blend.
Melt the chocolate chips. I melt them in the microwave for about 1 ½ minutes.
Add the melted chocolate chips and all other ingredients to the food processor.
Blend until everything is evenly mixed and smooth.
Notes
You can refrigerate this chocolate mousse to firm it up. It will get quite thick like an icing. This is how I prefer it because I find that after firming it up in the fridge, the taste of the avocado is less prominent.
