Preheat your oven to 350°F. Grease a 9-by-5-inch loaf pan with nonstick cooking spray and set aside. (possibly butter and flour might work better)
In a medium bowl, whisk together the flour, cocoa powder, baking soda, and sea salt. Set aside.
In a large bowl, add the eggs, melted butter, oil, vanilla extract, and brown sugar.
Stir until smooth. You might have a few small brown sugar clumps and that is fine.
Stir the dry ingredients into the wet ingredients, don’t overmix.
Stir in the shredded zucchini until just combined.
Stir in 3/4 cup of the chocolate chips.
Pour batter into prepared pan.
Sprinkle an additional 1/4 cup of chocolate chips over the top of the bread.
Bake for 45-50 minutes, or until a toothpick inserted into the center of the bread comes out mostly clean, you might have some melted chocolate chips on the toothpick and that is fine. You just don’t want a lot of gooey batter.
Remove the pan from the oven and set on a wire cooling rack.
Let the bread cool in the pan for 15 minutes. Run a knife around the edges of the bread and carefully remove from the pan.
Let the bread cool on the wire cooling rack until slightly warm.
Cut into slices and serve.
