In a food processor, blend the chickpeas, bananas, peanut butter, vanilla, and a splash of water or milk until smooth. Alternatively, mash everything with a fork for a chunkier texture.
In a bowl, combine the blended or mashed mixture with oats and shredded coconut. Stir well.
Gradually add water or milk until you reach your desired consistency. The oats will absorb liquid overnight, so leave it slightly runny.
Chop the dark chocolate into small chunks and mix it into the oats.
Top with shredded coconut and your favorite seeds.
Transfer the mixture into an airtight container and refrigerate overnight (or at least 4 hours).
