Chocolate Chip Zucchini Bread
Warm, tender, and studded with melty chocolate, this zucchini bread is an easy way to use up summer squash and get a sneaky veggie into breakfast or snack time. The crumb stays moist without being heavy, and chocolate chips add a familiar, crowd-pleasing finish—perfect for weeknight baking, school lunches, or a weekend coffee cake.
Why you’ll love this loaf
- Uses grated zucchini to add moisture (and extra veg) without a strong vegetable flavor.
- One-bowl wet mix keeps the process quick and low-mess.
- Kid-friendly, freezer-friendly, and flexible—swap chips for nuts or dried fruit.
“I made this on a whim with a zucchini mountain from the garden. It disappeared before dinner—moist, chocolaty, and perfectly sweet.” — home baker review
Step-by-step overview
- Preheat the oven and prepare a loaf pan.
- Grate zucchini and combine with the sugars, oil, eggs, and vanilla.
- Whisk dry ingredients separately (flour, leaveners, salt, cinnamon).
- Fold dry ingredients into the wet just until combined.
- Stir in chocolate chips, then bake in a greased 9×5-inch loaf pan.
- Cool briefly in the pan, then transfer to a rack to finish cooling before slicing.
Ingredients
- 2 cups grated zucchini (about 1 medium-large zucchini; medium grate; peel optional)
- 1 cup granulated sugar (can reduce to 3/4 cup for less sweetness)
- 1/2 cup brown sugar, packed (light or dark)
- 1/2 cup vegetable oil (substitute: mild-flavored olive oil, melted coconut oil, or 1/2 cup melted butter)
- 2 large eggs, at room temperature (for vegan: use 2 flax eggs — 2 tbsp ground flax + 6 tbsp water, mixed and rested)
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour (about 250 g; spoon into the cup and level — for denser loaf, try 1 cup white + 1 cup whole wheat)
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon (optional: 1/2 tsp nutmeg or pumpkin pie spice)
- 1 cup chocolate chips (semisweet, milk, or dark; mini chips distribute more evenly)
Notes: For gluten-free, swap in a 1:1 gluten-free baking flour blend and add 1/4–1/2 tsp xanthan gum if your blend doesn’t contain it. If your zucchini is very watery, see tips below about squeezing.
Directions
- Preheat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line it with parchment, leaving an overhang for easy removal.
- Grate the zucchini on a medium grater. No need to peel unless the skin is thick or waxed. Gently pat with a paper towel if extremely wet (see tips).
- In a large bowl, whisk together the grated zucchini, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla until smooth and evenly combined.
- In a separate bowl, whisk the flour, baking soda, baking powder, salt, and cinnamon to aerate and mix leaveners.
- Add the dry ingredients to the wet. Stir with a spatula just until you no longer see streaks of flour. Do not overmix; a few small lumps are fine.
- Fold in the chocolate chips gently so they’re evenly distributed. If you’re worried about chips sinking, toss them in 1–2 teaspoons of flour first.
- Pour the batter into the prepared pan and smooth the top with a spatula.
- Bake for about 55–65 minutes, or until the top is golden and a toothpick inserted into the center comes out clean or with a few moist crumbs (no wet batter). If the top browns too quickly, tent with foil after 35–40 minutes.
- Remove from the oven and let cool in the pan on a wire rack for 10–15 minutes. Run a knife around the edges, then lift the bread out using the parchment overhang (or invert onto the rack) and cool completely before slicing.
Baking notes: For convection ovens, reduce the temperature by 20°F (about 10–15 minutes shorter baking time); start checking at 45 minutes.
How to serve Chocolate Chip Zucchini Bread
- Slice thick and serve warm with butter or cream cheese.
- Toast briefly in a toaster oven for a lightly crisp edge and melty chips.
- For dessert, serve a slice with vanilla ice cream and a drizzle of chocolate sauce.
- Make mini slices for brunch platters or pack whole slices for lunchboxes.
- Garnish with a dusting of powdered sugar or a smear of whipped mascarpone for a fancier presentation.
How to store
- Room temperature: Once completely cool, wrap the loaf tightly in plastic wrap or store in an airtight container for up to 48 hours. Keep in a cool, dry place away from direct sun.
- Refrigerator: To extend freshness, refrigerate up to 5–7 days. Bring to room temperature before serving, or warm briefly.
- Freezer: Wrap the cooled loaf tightly in plastic and then foil, or slice and freeze individual slices in freezer bags. Freeze up to 3 months. Thaw overnight in the fridge or on the counter for a few hours.
- Food safety: Discard if you see mold or an off smell. Because this bread contains eggs and moist vegetables, refrigeration after 2 days helps slow spoilage in warm climates.
Reheating: Microwave a slice 10–20 seconds to warm. For a crisper exterior, heat at 325°F (160°C) in the oven for 8–12 minutes.
Helpful cooking tips
- Grating: Use a medium grater for best texture. Very finely shredded zucchini can make the loaf gummy; very large shreds give a chunkier crumb.
- Moisture control: Zucchini varies in water content. If it seems watery, squeeze lightly in a towel or handful of paper towels until most excess moisture is gone. Don’t dry it completely—some moisture keeps the bread tender.
- Measuring flour: Spoon flour into the measuring cup and level with a knife; don’t scoop directly with the cup (that can pack too much flour and make the loaf dense).
- Don’t overmix: Overworking the batter develops gluten and yields a tougher bread. Stir until just combined.
- Even chip distribution: Toss chocolate chips in a tablespoon of flour before folding in to reduce sinking.
- Pan prep: Lining with parchment that overhangs makes removal clean and easier. Greasing alone works fine but parchment is forgiving.
- Check doneness: Start checking at 50 minutes. A clean toothpick or internal temperature of 205–210°F (96–99°C) means the crumb has set.
- Flavor boost: Toast nuts or brown the butter for a richer, nuttier profile.
Variations
- Walnut Chocolate Chip: Add 1/2–3/4 cup chopped walnuts or pecans. Toast them first for more flavor.
- Orange-Chocolate: Add 1 tsp orange zest and use dark chocolate chips.
- Banana-Zucchini: Replace 1/2 cup oil with 1/2 cup mashed banana for extra flavor.
- Whole Wheat: Substitute half or all the flour with whole wheat pastry flour for nuttier taste and more fiber.
- Gluten-Free: Use a commercial 1:1 gluten-free flour blend; add 1/4–1/2 tsp xanthan if needed.
- Lower-sugar: Reduce the granulated sugar to 3/4 cup and use 3/4 cup brown sugar, or replace part of the sugar with a brown sugar substitute designed for baking (results will vary).
- Muffins: Spoon batter into a lined muffin tin and bake at 350°F (175°C) for 18–22 minutes for muffins.
FAQs
Q: Do I need to squeeze the zucchini before adding it to the batter?
A: Not always. If your zucchini is young and not very watery, you can add it as-is. If it feels soggy or releases a lot of liquid when grated, gently squeeze out excess moisture with a towel—removing some water prevents a soggy loaf while still keeping it tender.
Q: Can I make this into muffins instead of a loaf?
A: Yes. Fill a prepared 12-cup muffin tin about 2/3 full and bake at 350°F (175°C) for 18–22 minutes. Baking time will be shorter, so start checking at 16 minutes.
Q: How long does the bread keep, and can I freeze it?
A: At room temperature, it’s best eaten within 48 hours. Refrigerate for up to 5–7 days. Freeze wrapped well for up to 3 months. Thaw in the fridge or at room temperature and reheat if desired.
Q: Can I replace the eggs to make this vegan?
A: Yes—use two flax eggs (2 tbsp ground flax + 6 tbsp water, mixed and rested 5–10 minutes) or commercial egg replacer. Texture will be slightly different but still tender.
Q: Why did my bread come out dense or gummy?
A: Common causes: too much flour (measure incorrectly), overmixing the batter, or too much moisture from un-squeezed zucchini. Also check your leavening: old baking soda/powder can reduce rise.
Q: Can I use other mix-ins instead of chocolate chips?
A: Absolutely. Chopped nuts, dried cranberries, raisins, or white chocolate chips all work. Reduce the quantity of very wet add-ins (like fresh fruit) since they add moisture.
