Preheat the oven to 350 degrees F and line an 8X* baking pan with parchment paper or spray with cooking spray.
In the bowl of a stand mixer add the brown sugar.
In another microwave safe bowl, combine the chocolate and coconut oil. Microwave in 15-20 second increments until the chocolate is just melted.
With the mixer on low add in the chocolate mixture and continue mixing until mostly combined with the brown sugar.
Add eggs in one at a time and the vanilla extract. After the last egg, beat until just combined and then stop.
Using a wooden spoon, mix in the red wine, almond flour, coconut flour, cocoa power, and salt until just combined.
Pour into the prepared pan and bake for 38-40 minutes until the edges slightly pull away from the pan and the center is set. Let cool and cut into 9 pieces. Top with extra melted chocolate and flakey sea salt and enjoy!
