Preheat the oven to 350 degrees and grease a 9 by 13 inch baking dish.
In a large bowl, stir together the eggs, coconut oil, coconut milk, and maple syrup.
Add the flour and coconut to the wet ingredients. Stir to combine.
Pour the mixture into a 9 x 13 inch glass baking dish. Bake for 20 minutes, or until it's set. Remove the baking dish from the oven and pour the chocolate chips on top. Return the dish to the oven for a minute, until the chocolate chips melt. Then remove the dish from the oven and spread the chocolate evenly over the coconut base.
Let it cool for 5 minutes, then cut it into 16 bars while it’s still warm (before the chocolate has a chance to solidify). After they’re cut, let the bars cool in the pan before removing them
Store at room temperature for up to 3 days, or freeze for up to 3 months.
