Preheat the oven to 350 degrees F and line a baking sheet with parchment paper.

Mash the bananas in a mixing bowl until most of the lumps are out. Stir in the pure maple syrup and shredded coconut until very well combined. This mixture will be thick and sticky, but should come together easily.

Form small disc shapes out of the mixture and place on the baking sheet. (Note: you can poke holes in the center of the cookies to make them look like original Girl Scout cookies). Bake for 20 to 25 minutes, until the cookies are golden-brown around the edges and feel firm when poked.

Add the chopped chocolate bar (or chocolate chips) and coconut oil to a bowl and heat in the microwave for 20-second intervals, stirring very well in between intervals, until the chocolate has melted, about 1 minute total.

Dip each cookie in chocolate, and place it chocolate side up on the baking sheet until they dry. Once the chocolate has hardened, use the rest of the chocolate to drizzle on top (you may need to re-melt the chocolate in the microwave).
