Peel the bananas and cut into pieces. Put the banana pieces together with the desiccated coconut in a suitable container and puree the mixture. Season with vanilla if you like.
Line a baking sheet with parchment paper and spread the dough on it in portions. An ice cream scoop or tablespoon is suitable for this. Flatten the dough portions a little and shape them evenly with a spoon. Alternatively, the dough can be formed between the palms of the hands.
Bake the cookies (12-15 pieces) at 190 ° C (fan oven 180 ° C) for 20 to 25 minutes until the edge is lightly browned.
After they have cooled down a bit, the cookies can be decorated with chocolate or Nutella (normal or low carb / vegan) as desired.
