Preheat oven to 350 degrees.Line a 9 x 9 or 8 x 8 pan with aluminum foil or parchment paper. Lightly spray with cooking spray or grease with butter. Set aside.
Add butter to a medium saucepan and cook over medium heat until light brown / caramel in color. 5-10 minutes. Make sure to keep and eye on it so butter does not burn. It also helps to use a light colored saucepan for this.
Pour browned butter into a large bowl along with sugar, cocoa powder, salt, instant coffee granules and baking powder. Stir until combined and allow to rest for 5 minutes or until the mixture has cooled down.
Stir in the eggs and vanilla and mix until batter has a nice sheen to it.
Fold in the flour, shredded zucchini and chocolate chips just until combined. (Do not over mix)
Pour the batter into the prepared pan and bake for 25 minutes or until the top is set and a toothpick comes out slightly clean. (I like to underbake mine for extra fudgey brownies)
Cool completely and lift out the aluminum foil or parchment paper.
Frost with chocolate ganache cut into 9 brownies and serve!
Chocolate Ganache
Add chocolate chips and heavy cream to a medium microwave safe bowl. Heat in 15 second intervals until fully melted.Allow the ganache to cool for about 2-3 minutes. Pour and spread ontop of the cooled brownies.
Place back into the fridge to allow the ganache to set.
