Preheat your oven to 350°F (175°C) and line your baking pan with parchment paper, leaving some overhang for easy lifting.
In a small saucepan over low heat, melt the ghee and baker's chocolate, stirring occasionally until smooth. Remove from heat and let it cool slightly.
In a large mixing bowl, whisk together the melted chocolate mixture, vanilla extract, and eggs until well combined.
In another bowl, combine almond flour, cacao powder, monk fruit sweetener, cinnamon, baking powder, and sea salt. Mix until there are no clumps.
Gradually add the dry ingredients to the wet mixture, stirring until a thick batter forms. If desired, fold in sugar-free chocolate chips.
Pour the brownie batter into the prepared pan and spread it evenly. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Allow the brownies to cool in the pan for about 10 minutes before lifting them out using the parchment paper. Let them cool completely on a wire rack before slicing.
