Preheat oven to 350 degrees and grease two 8x4 bread pans well.
In a bowl, mix vegetable oil and greek yogurt together.
Add in brown sugar and granulated sugar, and mix until well combined.
Add in the eggs, one at a time, and mix until combined.
Sift in flour, cocoa powder, baking soda, and baking powder, and stir until combined.
Mix in salt, cinnamon, espresso powder.
Add in brewed coffee, shredded zucchini, and vanilla extract.
Stir in chocolate chips.
Divide batter evenly between both bread pans.
Mix cinnamon and sugar together and sprinkle on top of batter.
Bake for 50-55 minutes, or until a cake tester comes out clean.
Allow to cool 10 minutes before removing from the bread pans, and continue cooling on a wire rack.
Slice and enjoy!
