Grease a loaf pan and line with parchment. Preheat oven to 350ºF.
In a large bowl, whip eggs and sugars until lighter in color and mixture thickens slightly. This should only take a couple minutes whisking my hand.
While whisking, slowly stream in olive oil. Mix in vanilla and grated zucchini.
In a medium bowl sift flour, baking powder, baking soda, cinnamon, and salt. Stir in pine nuts and chocolate chips to coat in the flour mixture.
Gently stir dry ingredients into the wet until just combined. Be careful no to over mix.
Transfer batter to the prepared loaf pan. Sprinkle with Demerara sugar, if using.
Bake for 45-60 minutes until a toothpick inserted in the center comes out clan.
Let loaf cool in the pan for 15 minutes, then transfer to a wire rack to cool completely.*
Notes
*You can also eat it warm if you aren’t too concerned with getting a perfect slice! It’s also great toasted in a bit of butter the next day! Even better served warm with some vanilla ice cream as a fun dessert :)
