Ingredients You’ll Need
Dry ingredients
- 1 cup white whole wheat flour
- You can use regular whole wheat pastry flour or a 50/50 mix of all purpose and whole wheat if that is what you have.
- 1 cup all purpose flour
- I like King Arthur or Bob’s Red Mill because they measure consistently.
- 1/2 cup unsweetened cocoa powder
- Use natural cocoa, not hot cocoa mix. Dutch process also works and gives deeper color.
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1/2 teaspoon fine sea salt
- 1 teaspoon ground cinnamon
- Optional, but it rounds out the chocolate flavor nicely.
Wet ingredients
- 2 large eggs, room temperature
- 1/3 cup avocado oil or light olive oil
- Melted coconut oil also works; cool it slightly before mixing.
- 1/3 cup plain Greek yogurt (2% or 5%)
- This adds protein and moisture. Regular yogurt works; strain it a bit if it seems very thin.
- 1/3 cup pure maple syrup or honey
- 1/3 cup coconut sugar or light brown sugar
- You can use all maple syrup, though the loaf turns slightly more dense.
- 2 teaspoons pure vanilla extract
Zucchini and chocolate
- 2 cups finely grated zucchini, lightly packed
- Do not peel; the green flecks look pretty and stay very subtle.
- Gently squeeze out only excess dripping liquid with your hands; keep some moisture so the bread stays soft.
- 1/2 cup dark chocolate chips or chunks
- I like 60 to 70 percent cacao; mini chips distribute more evenly.
- 1/4 cup chopped walnuts or pecans (optional)
Pantry shortcuts and notes
- Use pre-shredded zucchini from the store in a pinch, but check for added salt and pat it dry.
- Use one-to-one gluten free baking flour to make this gluten free; I tested with Bob’s Red Mill 1:1 and it rose nicely.
- Swap zucchini with half grated zucchini and half grated carrot if you want a slightly sweeter loaf.
Equipment list
- 9 x 5 inch loaf pan
- Large mixing bowl
- Medium mixing bowl
- Whisk
- Spatula
- Box grater or food processor with shredding disc
- Cooling rack
- Parchment paper (helps lift the loaf out cleanly)
Tips & Tricks
- Grate zucchini on the small or medium holes so it melts into the batter and keeps the crumb tender.
- Squeeze zucchini gently; if you wring it dry, the bread turns out dense and crumbly.
- Use room temperature eggs and yogurt so the batter mixes smoothly and bakes evenly.
- Measure flour by spooning it into the cup and leveling with a knife to avoid a dry loaf.
- Stir the batter until the flour just disappears; overmixing makes tough bread.
- Line the pan with a parchment sling and lightly oil the sides so the loaf pops out easily.
- Sprinkle a few extra chocolate chips on top before baking for a bakery-style look.
- Let the bread cool at least 20 to 30 minutes before slicing so it holds its shape.
How to Make Healthy Chocolate Zucchini Bread Recipe
Step 1: Prep the pan and oven
Preheat your oven to 350°F. Lightly grease a 9 x 5 inch loaf pan and line it with a strip of parchment that hangs over the long sides. This makes lifting the bread out very simple.
Step 2: Grate and prep the zucchini
Wash and dry the zucchini. Grate it on the small or medium holes of a box grater. Scoop the grated zucchini into your hands and give it a gentle squeeze over the sink to remove drips, then fluff it and set it aside.
Step 3: Mix the dry ingredients
In a large bowl, whisk together the white whole wheat flour, all purpose flour, cocoa powder, baking soda, baking powder, salt, and cinnamon. Break up any cocoa lumps with the whisk. Set the bowl aside.
Step 4: Mix the wet ingredients
In a medium bowl, whisk the eggs until smooth. Add the oil, Greek yogurt, maple syrup, coconut sugar, and vanilla. Whisk until the mixture looks glossy and fully combined.
Step 5: Combine wet and dry
Pour the wet mixture into the bowl with the dry ingredients. Stir with a spatula until the flour almost disappears. The batter will look thick and a bit sticky, which works well here.
Step 6: Fold in zucchini and chocolate
Add the grated zucchini, chocolate chips, and nuts if you use them. Gently fold everything together until the zucchini distributes evenly and no dry pockets remain. The batter will loosen as the zucchini moisture blends in.
Step 7: Fill the pan and bake
Scrape the batter into the prepared loaf pan and smooth the top. Sprinkle a few extra chocolate chips on top if you want a pretty finish. Bake on the middle rack for 45 to 55 minutes, until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.
Step 8: Cool and slice
Place the pan on a cooling rack and let the bread cool in the pan for about 15 minutes. Use the parchment sling to lift the loaf out and set it directly on the rack. Cool another 15 to 20 minutes, then slice with a sharp serrated knife.
What to Serve with Healthy Chocolate Zucchini Bread Recipe
Serve a warm slice of Healthy Chocolate Zucchini Bread Recipe with a spoonful of Greek yogurt and fresh berries for a breakfast that feels like dessert. Pair it with a hot cup of coffee, cold brew, or a latte-style drink made with oat milk or almond milk. Kids love it with a glass of cold milk or chocolate oat milk for an after school snack. You can also pack slices in lunch boxes with a side of apple slices or orange segments.
Storage Success
- Keep the bread at room temperature in an airtight container for up to 3 days; place a paper towel under the loaf to catch extra moisture.
- Store slices in the fridge for up to 6 days; let them sit at room temp for 10 minutes before eating for the best texture.
- Freeze individual slices wrapped in parchment and tucked into a freezer bag for up to 3 months.
- Reheat slices in the microwave for 10 to 15 seconds or in a toaster oven at 300°F for 5 to 7 minutes until just warm and soft.
