Bake in the preheated oven for 20 to 22 minutes, or until a few crumbs are attached when a toothpick is inserted into the center, but it’s not too wet. Place on a wire rack to let it cool completely.
Place the chocolate chips or chopped chocolate in a small bowl. Heat the coconut milk for 20 to 30 seconds until the microwave until bubbling. Pour over the dark chocolate and let sit for 1 minute before stirring until smooth. Spread evenly over the cooled brownies and sprinkle with crushed candy canes and cacao nibs.
