Third time that week, my phone buzzed with texts — “Hey, can I get that recipe again?” Honestly, I wasn’t expecting such a fuss over zucchini bread, especially this double chocolate version with espresso glaze. It started kind of as an experiment—leftover zucchini from the garden, a craving for something chocolatey, and a random can of espresso in the pantry. But somehow, it turned into that quiet star of every gathering, the one that vanished in no time, leaving behind just crumbs and happy smiles.

What caught me off guard was how moist and rich the bread was, thanks to the zucchini’s secret magic.

What Ingredients You Will Need

This recipe keeps things straightforward with wholesome ingredients that work together to create a moist, flavorful bread with a rich chocolatey finish. The zucchini sneaks in moisture and subtle freshness, while the espresso glaze adds a sophisticated touch that’s surprisingly simple to whip up.

• For the bread:
• 1 ¾ cups (220g) all-purpose flour
• ¾ cup (65g) unsweetened cocoa powder (I like to use Dutch-processed for depth)
• 1 teaspoon baking soda
• ½ teaspoon baking powder
• ½ teaspoon salt
• 1 teaspoon ground cinnamon (optional, but adds warmth)
• 1 cup (200g) granulated sugar
• ½ cup (100g) packed brown sugar (adds moistness and caramel notes)
• 2 large eggs, room temperature
• ½ cup (120ml) vegetable oil or melted coconut oil
• 1 teaspoon pure vanilla extract
• 1 ½ cups (150g) grated zucchini (about 1 medium zucchini, squeezed to remove excess moisture)
• ¾ cup (130g) semi-sweet chocolate chips (feel free to swap for dark chocolate chips for a less sweet option)
• For the espresso glaze:
• 1 cup (120g) powdered sugar, sifted
• 1 tablespoon brewed espresso or strong coffee, cooled (instant espresso powder dissolved in water works well too)
• 1 teaspoon vanilla extract

If you’d rather keep it dairy-free, you can swap the oil for avocado oil or another neutral oil, and use dairy-free chocolate chips. For a gluten-free take, almond flour can work, but expect a denser texture. When zucchini is in season, fresh and firm zucchinis make the best bread, but frozen shredded zucchini (thawed and drained) can be a handy substitute.

Equipment Needed

• Loaf pan (9×5-inch / 23×13 cm) – standard size works perfectly for this recipe
• Mixing bowls – one large for wet ingredients, one for dry
• Box grater or food processor – for shredding zucchini finely
• Whisk and spatula – for combining ingredients thoroughly
• Measuring cups and spoons – accuracy helps with consistent results
• Cooling rack – important for letting the bread cool evenly
• Small bowl and spoon – to whisk together the espresso glaze

If you don’t have a box grater handy, a food processor with a shredding blade makes quick work of the zucchini. I’ve used standard loaf pans and silicone ones, but the metal pan tends to give a slightly crisper crust. Don’t forget to grease your pan well or line it with parchment paper to avoid sticking.

Preparation Method

1. Preheat your oven: Set it to 350°F (175°C) and grease your 9×5-inch loaf pan thoroughly or line it with parchment paper for easy removal. This step takes about 10 minutes, including warming up the oven.
2. Prepare the zucchini: Grate about 1 ½ cups (150g) of zucchini using a box grater or food processor. Place the shredded zucchini in a clean kitchen towel or paper towels and gently squeeze to remove some excess moisture. You want it moist but not dripping wet, which helps keep the bread from getting soggy.
3. Mix dry ingredients: In a medium bowl, whisk together 1 ¾ cups (220g) all-purpose flour, ¾ cup (65g) unsweetened cocoa powder, 1 teaspoon baking soda, ½ teaspoon baking powder, ½ teaspoon salt, and 1 teaspoon ground cinnamon (if using). Set aside.
4. Combine sugars and wet ingredients: In a large bowl, beat together 1 cup (200g) granulated sugar and ½ cup (100g) packed brown sugar with 2 large eggs until the mixture is smooth and slightly fluffy (about 2-3 minutes). Add ½ cup (120ml) vegetable oil and 1 teaspoon pure vanilla extract, mixing gently until combined.
5. Incorporate zucchini and chocolate chips: Fold the shredded zucchini and ¾ cup (130g) semi-sweet chocolate chips into the wet ingredients. The zucchini adds moisture and subtle freshness, while the chips create pockets of melty chocolate throughout.
6. Combine wet and dry ingredients: Gradually add the dry mixture to the wet, folding gently with a spatula until just combined. Overmixing can make the bread dense, so stop as soon as you see no flour.
7. Pour batter into pan: Transfer the batter into your prepared loaf pan, smoothing the top with a spatula. The batter will be thick and fudgy.
8. Bake: Place the pan in the preheated oven and bake for 50-60 minutes. Start checking at 50 minutes by inserting a toothpick into the center; it should come out with a few moist crumbs attached but not wet batter. If your oven bakes unevenly, rotate the pan halfway through.
9. Cool: Let the bread cool in the pan for about 15 minutes, then transfer it to a cooling rack to cool completely before glazing. This helps the glaze set nicely and prevents it from melting off.
10. Make the espresso glaze: In a small bowl, whisk together 1 cup (120g) sifted powdered sugar, 1 tablespoon brewed espresso (or strong coffee), and 1 teaspoon vanilla extract until smooth. Adjust the thickness by adding more powdered sugar (for thicker glaze) or a bit more espresso (for thinner glaze).
11. Glaze the bread: Drizzle the espresso glaze evenly over the cooled bread. Let it set for 15-20 minutes before slicing and serving.

Pro tip: If your zucchini is very watery, patting it dry well before adding will make a noticeable difference in the final texture. Also, the espresso glaze can be made ahead and refrigerated; just give it a good stir before using. I once forgot to add baking soda and ended up with a very dense loaf—don’t skip that step!

Cooking Tips & Techniques

Getting that perfect moist, double chocolate zucchini bread with a smooth espresso glaze isn’t just about following the recipe; it’s about a few key tricks I’ve picked up along the way.

• Don’t overmix: When combining wet and dry ingredients, fold gently to avoid activating too much gluten. Overworking the batter leads to a tough loaf rather than a tender crumb.
• Drain your zucchini well: Soggy zucchini can make the bread dense and gummy. Wrapping it in a clean towel and squeezing out excess water makes a difference.
• Use good quality cocoa: Dutch-processed cocoa powder adds a richer flavor and deeper color, but natural cocoa works fine if that’s what you have. Just expect a slightly different flavor profile.
• Chocolate chips matter: Semi-sweet works best here, but dark or even white chocolate chips can add different flavor notes. I once tried a mix of dark and milk chocolate chips for a fun twist.
• Espresso glaze balance: The glaze should be smooth and pourable, not runny or too thick. If your glaze is too thick, a little extra brewed espresso or milk can loosen it up. Too thin? Add more powdered sugar.
• Timing matters: Baking times can vary by oven, so start checking at 50 minutes. The bread continues to set as it cools.
• Cooling is key: Don’t glaze hot bread—it’ll melt the glaze and make a mess. Patience pays off here.

For a subtle flavor boost, I sometimes add a pinch of instant espresso powder right into the batter—it intensifies the chocolate without making it taste like coffee. Also, if you’re short on time, mini loaf pans bake faster but adjust timing accordingly.

Variations & Adaptations

One of the best things about this recipe is how easy it is to tweak to suit your preferences or dietary needs.

• Nutty twist: Add ½ cup chopped walnuts or pecans to the batter for crunch and extra flavor. Toasting the nuts first gives a lovely depth.
• Gluten-free option: Swap the all-purpose flour for a gluten-free blend like Bob’s Red Mill 1-to-1 baking flour. The texture will be slightly different but still delicious.
• Dairy-free and vegan: Use coconut oil or avocado oil instead of vegetable oil, and replace eggs with flax eggs (1 tablespoon flaxseed meal + 3 tablespoons water per egg, let sit 5 minutes). Use dairy-free chocolate chips and a glaze made with dairy-free powdered sugar.
• Spiced up: Add ½ teaspoon ground ginger or a pinch of cayenne for a warming kick.
• Seasonal fruit: Fold in ½ cup fresh or frozen raspberries or cherries for a fruity surprise. This reminds me of the fruity notes in the lemon glazed zucchini cookies from the site—bright and luscious.

Personally, I’ve made a version with dark chocolate chunks and a sprinkle of sea salt on top of the glaze—such an addictive combo. And if you want to skip the glaze, dusting with powdered sugar works well too.

Serving & Storage Suggestions

Serve this double chocolate zucchini bread slightly warm or at room temperature, ideally with a hot cup of coffee or tea to complement the espresso glaze’s notes. It’s excellent as a breakfast treat or a late-night snack when you want something sweet but not too heavy.

For gatherings, slicing it into thick pieces and arranging on a platter makes a lovely presentation. You can even add a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence.

Storage is straightforward:

• Room temperature: Wrap the bread tightly in plastic wrap or store in an airtight container for up to 3 days.
• Refrigerator: Keeps well for up to a week wrapped tightly; just bring to room temperature before serving to soften the crumb.
• Freezer: Wrap slices or the whole loaf in foil and plastic wrap, then freeze for up to 3 months. Thaw overnight in the fridge or for a few hours at room temp.

Reheat slices gently in the microwave for 15-20 seconds or in a toaster oven to revive that fresh-baked warmth. The flavors deepen a bit after a day or two, so sometimes I make it a day ahead for parties.
