Preheat oven to 350º F. Lightly grease an 8 1/2" x 4 1/2" loaf pan. Set aside.
In a large bowl or bowl of a stand mixer, beat the 2 large eggs, 1/3 cup honey, 1/2 cup olive oil, 1/2 cup brown sugar, and 1 tsp vanilla until smooth.
In a medium bowl, add 1 2/3 cups all purpose flour, 1/3 cup cocoa powder, 1 tsp salt, 1 tsp ground cinnamon, 1 tsp instant coffee, 1 tsp baking soda, 1/2 tsp baking powder and stir to combine. Add the dry ingredients to the egg mixture and mix just until combined.
Stir in 2 cups zucchini and 1 cup chocolate chips until just combined. Pour into the prepared pan.
Bake for 65-75 minutes, or until a toothpick inserted in the center comes out clean. Remove from the oven and cool for 10-15 minutes before turning out onto a wire rack to cool completely.
