You will need a small loaf pan (8×4) and parchment paper.
Line the loaf pan with parchment paper, and pre-heat the oven to 350F.
Chop up the chocolate and combine half of it with the coconut oil. Set the rest aside.
Microwave the chocolate and coconut oil for 30 seconds to melt. Stir until smooth.
Crack the eggs into a medium bowl, slowly pour in the melted chocolate mix while you whisk the eggs until thick and combined. Doesn’t have to be totally smooth. Use a spatula to scrape any left-over chocolate in there.
Whisk together the dry ingredients into a separate bowl then add in the wet mix and use a spatula to fold it all together until the batter is thick and dark brown. Fold in the rest of the chopped chocolate.
Use the spatula to scrape all of the batter into the loaf pan and smooth it out.
Chop up the nuts and mix in a small bowl with the cinnamon, sweetener and peppermint. Then spoon it over the brownie batter.
Place in the center rack and bake for 30 minutes or until a toothpick comes out almost clean when inserted in the center.
Remove from the oven and let it cool. Lift up the brownie by the parchment paper and place on a cutting board. Cut in to 8 even squares.
