Line a baking sheet or a couple of plates with parchment paper. Set aside until needed.
Cut the dates in half lengthwise, being careful not to slice the date all the way in half, you want to be able to stuff the dates with your filling. Remove the pits.
In a large skillet, melt the butter and brown sugar over medium to medium high heat. Whisk together until the butter and sugar are well combined. Don't worry if the mixture looks grainy. Once the butter/sugar start to bubble, carefully add the banana's, flat size down. Cook the banana's for 3 minutes, then using 2 forks, gently flip the banana's and cook for another minute.
TURN OFF THE HEAT and add the rum. Once the rum is added, turn the heat back on. If you have a gas stove, you can gently tip your pan to one side until the rum ignites. If you're working on an electric stove, get a long fire lighter (or match) and careful ignite the rum. Be careful, but don't panic, your pan will be aflame but will burn out in a minute or two, once the rum burns off.
Once the fire dies down, sprinkle in some cinnamon, and carefully stir everything together. Set aside and allow banana's to cool and cut into small chunks.
Once the banana's are cool, stuff the dates with some banana, then spoon over some brown sugar sauce left over in the pan. Repeat until all of the dates are stuffed with banana and sauce.
Put the dates into the freezer and chill while you melt the chocolate in a double boiler (or microwave).
Once the chocolate is completely melted, take the dates out of the freezer, and one by one, dunk the dates into the melted chocolate using a fork. Carefully lift the chocolate covered dates out of the chocolate, allowing the access chocolate to drip off.
Carefully placed the chocolate cover dates onto the parchment paper and top with shredded coconut or any topping you wish. After you topped the dates with whatever topping you enjoy, pop them into the fridge for an hour or until the chocolate firms up and sets.
Keep stored in an airtight container in the fridge. Enjoy!
