In a small bowl, combine 2 tablespoons of the coconut cream with the gelatin and set aside.
Slice a banana in half: saving one half of it for blending, and chopping the other half into small pieces.
To a blender or food processor, add the remaining coconut cream, maple syrup or honey, vanilla, sea salt, and 1/2 of the banana. Pulse until smooth.
Transfer the smooth mixture to a medium saucepan over medium heat, and stir in the cocoa powder. Bring the mixture to a low boil, then remove it from the heat.
Whisk in the gelatin mixture. Let it cool to room temperature, then stir in the chopped banana, chopped walnuts, and chocolate chips.
Cover the bowl and transfer to the fridge, chilling until thick and creamy. Give it a stir every 30 minutes or so to keep it smooth without a "skin" forming on top. Top with extra banana, walnuts, and chocolate chips if you're feeling fancy.
Serve chilled, sitting out at room temperature for a few minutes to soften if you'd like. Enjoy!
