Ready to make it? Here is the full step-by-step recipe:

This zucchini bread cake mix recipe turns a box of chocolate cake mix and fresh garden zucchini into the moistest, fudgiest quick bread you'll ever bake, in just one bowl.
Preheat the oven to 350 degrees F (175 degrees C). Grease and lightly flour a 9x5 inch loaf pan, or line with parchment paper.
Grate the zucchini on the large holes of a box grater. Place the grated zucchini in a clean kitchen towel or paper towels and squeeze out as much excess liquid as possible.
In a large mixing bowl, whisk together the cake mix, eggs, oil, water, vanilla extract, and cinnamon (if using) until smooth and no dry streaks remain.
Fold in the grated zucchini until evenly distributed through the batter.
Gently fold in the chocolate chips, reserving a small handful to sprinkle on top.
Pour the batter into the prepared loaf pan and smooth the top with a spatula. Sprinkle the reserved chocolate chips over the surface.
Bake for 45 to 55 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
Cool the bread in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing.
This bread is delicious slightly warm, straight from the cooling rack, but it slices more cleanly once fully cooled. Store leftovers wrapped tightly at room temperature for up to 3 days, or refrigerate for up to a week if your kitchen runs warm.
For longer storage, this loaf freezes wonderfully. Wrap individual slices in plastic wrap, then place them in a freezer bag for up to 3 months. Thaw at room temperature or microwave for a quick treat.
If you're working through a big garden harvest, this same method works beautifully as a batch of easy zucchini muffins recipes too. Simply divide the batter into a lined muffin tin and reduce the bake time to 18 to 22 minutes. It's one of the most versatile ways to use up large zucchini recipes baking projects tend to call for, and it turns a simple vegetable into a treat everyone will ask for again.
