Make the mousse:
Melt chocolate in a double-boiler, being careful not to overheat or burn.
Scrape into a blender with all other ingredients. Blend until very smooth--a few pulses at the end will help get it all in there. Scrape down mousse as needed to ensure a perfectly smooth texture.
Crush two Oreos by placing in a Ziploc bag and beating gently with a rolling pin--you want crushed Oreos, not Oreo dust! Layer mousse and Oreos in individual serving bowls, the amount of Oreos is up to you! We used about 2 per serving. Top with crushed Oreos.
Refrigerate for two hours.
