01 - Place chopped vegan dark chocolate in a heatproof bowl set over a saucepan of gently simmering water. Stir occasionally until completely melted and smooth. Remove from heat and cool slightly.
02 - In a blender or food processor, combine drained silken tofu, melted chocolate, maple syrup, vanilla extract, and plant-based milk. Blend mixture until silky and homogeneous, scraping down the sides to ensure an even texture.
03 - Spoon the chocolate mousse evenly into 6 small serving cups or jars. Tap each vessel gently to settle and level the mousse.
04 - Cover cups and refrigerate for a minimum of 2 hours. Allow mixture to set thoroughly before garnishing.
05 - Just prior to presentation, sprinkle a generous layer of crushed vegan chocolate sandwich cookies over the surface of each mousse cup to resemble soil.
06 - Pipe or write spooky messages, such as “RIP,” on each rectangular vegan cookie with icing or melted chocolate. Insert one decorated tombstone cookie vertically into each cup.
07 - Finish each cup with vegan gummy worms, edible flowers, or fresh herbs, according to preference.
