Flaky SaltTo serve (optional)Balances richness

Step-by-Step Directions

  1. Prep the Pans:
    Preheat oven to 350°F. Lightly grease two 9-by-5-inch loaf pans with oil. Line each pan with parchment, leaving an overhang on each long side for easy removal; grease the parchment too.
  2. Mix the Chocolate Chips:
    In a small bowl, combine the bittersweet and milk chocolate chips. Reserve half a cup for topping later.
  3. Combine Dry Ingredients:
    In a large bowl, whisk together flour, cocoa powder, espresso powder, baking powder, baking soda, and salt until blended.
  4. Combine Wet Ingredients:
    In a second large bowl, whisk oil, eggs, granulated sugar, brown sugar, sour cream, and vanilla until smooth and fully combined.
  5. Make the Batter:
    Add wet ingredients to dry and stir until just incorporated. Do not overmix. Fold in grated zucchini and all remaining chocolate chips, except the reserved topping. The batter will be thick.
  6. Prepare for Baking:
    Divide the batter evenly between the prepared pans. Use a spoon or offset spatula to smooth the tops. Sprinkle the reserved half-cup of chocolate chips over each loaf.
  7. Bake:
    Bake for about 1 hour, rotating pans halfway through. Check for doneness: the bread should spring back when lightly pressed, edges will pull away from the pan, and a toothpick inserted should come out with just a few crumbs (don’t mistake melted chocolate for raw batter).
  8. Cool and Serve:
    Cool in pans for at least 30 minutes, then gently lift the loaves out using the parchment overhang. Allow to cool completely. Sprinkle with flaky salt if desired, then slice and serve.

Expert Tips

  • Don’t peel the zucchini: The skin is soft and unnoticeable after grating; it adds color, nutrition, and tender moisture.
  • How to grate zucchini: Use a box grater (largest holes) or a food processor’s grating attachment. No need to squeeze out moisture unless zucchini is excessively wet.
  • Chocolate chips: For extra contrast, try a mix of white, milk, and bittersweet chocolate chips, but keep total quantity the same.
  • Storage: Wrap cooled bread tightly and store up to 3 days at room temperature, or freeze for up to 3 months.

Making the Most of Zucchini and Chocolate

This recipe shines brightest at the peak of summer, when zucchini is so abundant it begs for creative use. Turning vegetables into dessert is a classic move for gardeners, and the result is rich, chocolaty, and moist — never dry or heavy. Skeptics won’t believe hidden zucchini could taste this good!

FAQs: Your Burning Zucchini Bread Questions

Should zucchini be peeled for bread?
No, leave the skin on! Grated zucchini skin is soft and blends right into the batter for nutritious, colorful bread — saving you time and effort.
How do you grate zucchini for bread?
Trim off ends and, if zucchini is large, cut in half crosswise. Grate using a box grater’s largest holes, or use a food processor with grating attachment for convenience.
Can you substitute with other vegetables?
While possible, zucchini’s neutral taste and high moisture are ideal; swap with shredded carrots or yellow squash, but expect subtle changes in texture and color.
Why add espresso powder?
Espresso powder intensifies the chocolate flavor without adding noticeable coffee taste. It’s optional but recommended for deeper chocolatey richness.
Can you freeze zucchini bread?
Absolutely. Cool loaves fully, wrap tightly in plastic and foil, then freeze for up to three months. Thaw on the counter overnight for best texture.
How do you know when it’s done baking?
Loaves should spring back when pressed; toothpick or skewer should come out mostly clean, except for melted chocolate smears — look for crumbs, not gooey batter.

Variations and Serving Suggestions

  • Serve with Ice Cream: Warm slices pair beautifully with vanilla bean ice cream.
  • Add Nuts: Fold in 1 cup chopped walnuts or pecans for crunch.
  • Mocha Twist: Increase espresso powder and drizzle with coffee glaze after cooling.
  • Double Chocolate Drizzle: Melt extra chips and pour over cooled loaf for glossy topping.
  • Portable Snacks: Bake batter in muffin tins, reduce bake time to 25–30 minutes.

Frequently Asked Questions (FAQs)

Q: Can I use Greek yogurt instead of sour cream?

A: Yes, full-fat Greek yogurt works well in place of sour cream and provides similar moisture and tang.

Q: Is this bread gluten-free?

A: Not as written. Substitute a 1:1 gluten-free baking flour for all-purpose flour to make a gluten-free version.

Q: What’s the best way to store leftover bread?

A: Wrap loaf well and store at room temperature for up to three days, or freeze individual slices for longer storage.
