Sprinkle the packet of gelatin on top of ½ cup cold milk. Set aside for 5 minutes.
In a small saucepan, heat up cream and sugar (do not boil). Add cocoa a little bit at a time and stir thoroughly. Once sugar dissolves, pour over the bloomed gelatin. Stir until gelatin dissolves, and add ¼ cup of amaretto. Strain mixture to remove cocoa powder clumps – there will be clumps! Pour into mold(s) and refrigerate for 4 hours.
