Melt the butter and 5 oz of chocolate together in a double boiler.
Stir in the coffee and sugar. Remove from the stove and add the eggs, one after another. Mix in the vanilla extract, salt, and cocoa. Stir in the flour.
Line a baking form with baking parchment and pour in your batter. Bake for 30 to 35 minutes at 350° F.
Put the coconut flakes into a bowl and mix them together with the condensed milk.
In a separate bowl microwave 3.5 oz of chocolate with the whipping cream for 1 minute.
Spread the coconut cream over the baked brownie cake, then pour the chocolate sauce on top. Refrigerate for an hour. Carefully remove from the baking form and cut into pieces to serve.
