Ingredients You’ll Need

Dry ingredients

1 cup white whole wheat flour
- Use white whole wheat for a lighter texture than regular whole wheat.
¾ cup all-purpose flour
- This combo keeps the bread tender and still adds fiber.
½ cup unsweetened cocoa powder
- Use natural cocoa like Hershey’s or store brand; Dutch-process also works and gives deeper flavor.
1 teaspoon baking soda
½ teaspoon baking powder
½ teaspoon fine sea salt
1 teaspoon ground cinnamon
- Optional but adds warmth that pairs nicely with chocolate.

Wet ingredients

2 large eggs, room temperature
⅓ cup olive oil or avocado oil
- Use a neutral-tasting olive oil; extra virgin can taste strong in baked goods.
⅓ cup plain Greek yogurt (2% or 5%)
- Adds protein and moisture; regular yogurt also works, just drain off excess liquid.
½ cup maple syrup or honey
- Maple syrup gives a softer sweetness; honey tastes a bit stronger.
¼ cup coconut sugar or light brown sugar
- Keeps sweetness balanced without going overboard.
2 teaspoons pure vanilla extract

Zucchini and chocolate

1½ cups finely grated zucchini, lightly packed
- About 1 medium zucchini; do not peel.
½ cup dark chocolate chips or chunks
- I like 60–70 percent cacao; mini chips distribute more evenly.

Optional add-ins

¼ cup chopped walnuts or pecans
2 tablespoons mini chocolate chips for sprinkling on top

Equipment

9×5 inch loaf pan
Mixing bowls (one large, one medium)
Whisk and rubber spatula
Box grater for zucchini
Measuring cups and spoons
Parchment paper or nonstick spray
Wire rack for cooling

Tips & Tricks

Squeeze zucchini gently in a clean towel if it feels very wet, but keep some moisture so the bread stays soft.
Pack grated zucchini lightly in the cup; do not cram it or the batter turns too dense.
Use room temperature eggs and yogurt so the batter mixes smoothly and bakes evenly.
Stir the batter just until no dry streaks remain; overmixing makes the loaf tough.
Line the loaf pan with parchment and leave a little overhang so you lift the bread out easily.
Sprinkle a few chocolate chips on top before baking for a bakery-style look.
Check doneness with a toothpick in the center; a few moist crumbs and melted chocolate count as done.
Let the bread cool at least 20 to 30 minutes before slicing so it holds its shape.
Slice with a serrated knife to avoid squishing the loaf.
Double the recipe and bake two loaves if you want freezer snacks for busy weeks.

How to Make Healthy Chocolate Zucchini Bread Recipe

Mix the dry ingredients

Preheat your oven to 350°F and place a rack in the center.
Grease a 9×5 inch loaf pan and line it with a parchment sling.
In a medium bowl, whisk together white whole wheat flour, all-purpose flour, cocoa powder, baking soda, baking powder, salt, and cinnamon until the mixture looks uniform and no cocoa clumps remain.

Prep the zucchini and wet ingredients

Wash the zucchini, trim the ends, and grate it on the small holes of a box grater.
Lightly squeeze the grated zucchini over the sink or a bowl to remove excess water, then measure 1½ cups and set aside.
In a large bowl, whisk eggs, oil, Greek yogurt, maple syrup, coconut sugar, and vanilla until the mixture looks smooth and glossy.

Combine everything

Add the dry ingredients to the wet ingredients in two additions and fold gently with a spatula.
When a few flour streaks remain, fold in the grated zucchini and chocolate chips until just combined.
If you use nuts, fold them in now and stop mixing as soon as everything looks evenly distributed.

Bake the bread

Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Sprinkle extra mini chocolate chips on top if you want a pretty finish.
Bake for 45 to 55 minutes, until a toothpick inserted in the center comes out with moist crumbs and melted chocolate but no raw batter.

Cool and slice

Place the pan on a wire rack and let the bread cool in the pan for about 15 minutes.
Use the parchment sling to lift the loaf out of the pan and set it on the rack.
Let it cool another 15 to 20 minutes, then slice with a serrated knife and serve warm or at room temperature.
