Start by placing the unsalted butter in the Ziplock bag with the unpeeled bananas.
Transfer to a large skillet over medium heat with boiling water and cook for 5 minutes.
After this time has passed, remove from the heat and peel the bananas.
Transfer them to a plastic container and mash them very well until smooth.
Next, chop the chocolate into smaller pieces and transfer to a medium bowl.
Microwave it at maximum power in 30-second intervals, always stirring after each interval until completely melted.
Add the melted chocolate to the container with the bananas and mix to incorporate.
Next, add the juice of one lemon, the ground cinnamon, the vanilla extract, mix again and arrange evenly.
