Chop the chocolate into small chunks and put it in a bowl. Melt in microwave or using double boiler. Set aside.

Add sugar, applesauce, egg, vanilla extract into a bowl and whisk just to combine. Then sift in the flour, salt, baking soda and cocoa powder. Mix just to combine again, don't over mix. Then add in grated zucchini and mix to combine.

Now add in the melted chocolate and mix everything together for one last time. Pour the batter into a buttered 8x8 inch (20x20 cm) pan and spread it evenly.

Bake in a preheated oven at 350ºF (175ºC) for 40 minutes or until when you insert a skewer stick it comes out slightly crumbly wet. If it comes out clean, it means that you've over baked it.

Remove from the oven and set aside to cool completely.

Chop the chocolate and place it in a bowl. Heat cream until it's about to simmer and then pour it into the bowl with chocolate. Leave untouched for 3 minutes.

Gently whisk until the mixture comes together. Pour onto the cooled brownies and spread evenly. Place in the fridge for 30 minutes or until the chocolate sets. Then simply slice and enjoy!
