Moist Chocolate Chip Zucchini Bread (One Bowl)

This chocolate chip zucchini bread is the type of recipe you’ll pull out every summer when zucchini piles up on the counter. It takes one bowl, zero fuss, and turns a humble vegetable into a loaf that feels like dessert.

The crumb is soft and tender, studded with melted puddles of chocolate, and the zucchini disappears into the batter so well that even picky eaters won’t suspect a thing. You get a whole cup of grated zucchini in every slice without any green flavor, just moisture that keeps the bread fresh for days.

What Makes This Bread a Keeper

This is the zucchini bread I keep coming back to. It’s built for real life. You don’t need a mixer, you don’t need to squeeze the zucchini dry, and everything comes together in about 15 minutes before the loaf hits the oven.

The zucchini does the heavy lifting here. Instead of adding extra oil or applesauce, the natural water in the squash steams inside the batter, creating that soft, almost fudgy crumb. And the chocolate chips sink into the loaf and melt into little pockets that make each slice taste indulgent, even though you’re eating a vegetable.

Most zucchini breads ask you to wring out the moisture. I skip that step on purpose. It’s the one thing that makes this version more tender than the rest, and it means less work for you.

Ingredients

• 1 1/2 cups grated zucchini (about 1 medium): do not squeeze dry; the moisture is what makes this bread tender.
• 1/2 cup neutral oil (vegetable, canola, or melted coconut oil): keeps the loaf soft for days.
• 3/4 cup granulated sugar: sweetens without weighing down the crumb.
• 1/4 cup packed light brown sugar: adds a hint of caramel and helps the top bake deeply golden.
• 2 large eggs: bind the batter and add structure.
• 1 tsp vanilla extract: rounds out the sweetness.
• 1 1/2 cups all-purpose flour: spoon and level it for a light crumb, not a dense loaf.
• 1 tsp baking soda: gives the bread its lift.
• 1/2 tsp baking powder: works with the soda for an even rise.
• 1/2 tsp salt: balances the sugar and brings out the chocolate.
• 1 tsp ground cinnamon: the warm note that pulls it all together; you can bump it to 1 1/2 tsp if you love cinnamon.
• 1 cup semisweet chocolate chips, divided: half goes into the batter, the rest gets scattered on top for a bakery look.

Variations / Substitutions

• Use dark or white chocolate: dark chocolate chunks give a more bittersweet loaf; white chocolate chips make it sweeter and creamier.
• Add nuts: fold in 1/2 cup chopped walnuts or pecans for crunch.
• Swap in whole wheat flour: replace up to half the all-purpose flour with whole wheat pastry flour for a heartier crumb; the texture will be a bit denser.
• Make it dairy free: use a neutral oil and dairy free chocolate chips; the recipe is otherwise dairy free.
• Try a different spice: a pinch of nutmeg or cardamom adds a cozy twist.

How to Make Chocolate Chip Zucchini Bread

Step 1: Mix the Wet Ingredients

Preheat your oven to 350°F (175°C) and grease a 9×5 inch loaf pan, then line it with parchment paper for easy lifting. In a large bowl, whisk together the 1/2 cup oil, 3/4 cup granulated sugar, 1/4 cup brown sugar, 2 eggs, and 1 tsp vanilla until smooth and slightly lighter in color.

Stir in the 1 1/2 cups grated zucchini. The mixture will look thin and a little speckled from the peel, which is exactly what you want. Do not drain it; the liquid from the zucchini will blend with the flour to keep the bread moist.

Step 2: Combine the Dry Ingredients and Fold

Add the 1 1/2 cups flour, 1 tsp baking soda, 1/2 tsp baking powder, 1/2 tsp salt, and 1 tsp cinnamon directly into the wet bowl. Switch to a spatula and fold everything together just until you no longer see streaks of flour.

The batter will be thick and a bit lumpy. Stop as soon as the flour disappears; overmixing develops gluten and can make the bread tough instead of tender.

Step 3: Fold in the Chocolate Chips

Pour in about 3/4 cup of the chocolate chips and fold a few times to distribute them. Reserve the remaining 1/4 cup for the top.

The chips will be suspended throughout the batter, and a few pieces of zucchini might still be visible. That’s fine; they’ll soften in the oven.

Step 4: Bake the Loaf

Scrape the batter into the prepared pan and smooth the top. Sprinkle the reserved chocolate chips evenly over the surface and press a few gently into the batter so they stick.

Bake for 50 to 60 minutes, until the top is deeply golden and a toothpick inserted into the center comes out with just a few moist crumbs. Melted chocolate on the toothpick is okay. If the top browns too quickly, tent the pan with foil after 40 minutes.

Step 5: Slice and Serve

Let the bread cool in the pan for 10 minutes, then lift it out using the parchment sling and transfer it to a wire rack. Cool for at least 30 minutes before slicing; cutting while it’s hot can make the crumb gummy.

Slice thick pieces while the bread is still a little warm, and watch the chocolate chip pockets stretch as you pull the knife through. Any leftovers keep beautifully in the fridge.

Tips for the Best Zucchini Bread

• Use a coarse grate: A box grater with the large holes gives the right texture; fine grating releases too much liquid and can make the bread dense.
• No need to peel: The green flecks of peel add color and a whisper of earthy flavor, but you can peel if you prefer a uniform look.
• Measure flour carefully: Spoon flour into the measuring cup and level it off with a knife. Scooping directly from the bag packs in extra flour and yields a dry loaf.
• Check for doneness early: Ovens vary; start checking at 50 minutes and go by the toothpick, not the clock.
• Let it rest: The flavor deepens as the bread cools. It tastes even better the next day, and the chocolate chips stay melty even at room temperature.

Bake times by pan:

Keeping Leftover Zucchini Bread

• Refrigerate: Store in an airtight container in the fridge for up to 5 days. The bread stays soft and the chocolate chips keep their sheen.
• Freeze: Wrap the whole loaf or individual slices tightly in plastic wrap, then place in a freezer bag. Freeze for up to 3 months. Thaw at room temperature or pop a frozen slice in the toaster.
• Reheating: Warm a slice in the microwave for 15-20 seconds to bring back that just-baked meltiness.

Frequently Asked Questions

Can I reduce the sugar?

Yes, you can cut the granulated sugar to 1/2 cup and keep the brown sugar. The bread will be less sweet but still very moist; the chocolate chips carry a lot of the sweetness.

Can I use a gluten-free flour blend?

A 1:1 gluten-free baking blend works well here. Choose one that contains xanthan gum, and expect the crumb to be a little more crumbly than the original.

Why did my bread sink in the middle?

It’s usually a sign of underbaking. Make sure the toothpick test comes out with just a few moist crumbs, not wet batter. Opening the oven door too early can also cause a sink, so wait until at least 40 minutes before peeking.

Can I leave out the chocolate chips?

Absolutely. The recipe makes a lovely plain zucchini bread. You can add up to 1/2 cup chopped nuts or raisins instead, or skip the mix-ins entirely and dust the top with cinnamon sugar before baking.

Notes

The bread tastes even better the next day; store it in the fridge and let slices come to room temperature or warm briefly before serving. If your loaf browns too fast, tent it loosely with foil at the 40-minute mark.
