The moistness from the zucchini pairs perfectly with the rich chocolate, making every bite a delightful surprise. It’s the perfect way to sneak in some extra veggies while satisfying your sweet tooth! Ever since I started baking, I knew I would share this recipe and others similar to it, like my classic copycat Texas Roadhouse Rolls.

Growing up, my grandmother always found creative ways to incorporate vegetables into our desserts. I remember being skeptical at first, but one bite of her zucchini bread, and I was hooked! Those memories in her kitchen, filled with laughter and the aroma of freshly baked goods, are some of my fondest.

This recipe is not only incredibly delicious but also surprisingly easy to make, even on busy weeknights. It’s a comforting and stress-free bake that always brings a smile to everyone’s face. My secret is to use high-quality cocoa powder for the richest chocolate flavor.

Ingredients
  

Dry Ingredients
  • 2 1/2 cups All-Purpose Flour spooned and leveled
  • 3/4 cup Unsweetened Cocoa Powder
  • 1 tsp Baking Soda
  • 1 tsp Baking Powder
  • 1/2 tsp Salt
Wet Ingredients
  • 1 3/4 cups Granulated Sugar
  • 1/2 cup Vegetable Oil
  • 2 Large Eggs at room temperature
  • 2 tsp Vanilla Extract
  • 1 cup Buttermilk at room temperature
Zucchini & Chocolate
  • 2 cups Zucchini grated, do not squeeze excess moisture
  • 1 cup Chocolate Chips semi-sweet or dark

Equipment

  • 9x5 inch loaf pan
  • Mixing Bowls
  • Whisk
  • Rubber spatula

Method
 

Get Started
  • Preheat oven to 350°F (175°C). Grease and flour a 9x5 inch loaf pan. Alternatively, line with parchment paper, leaving an overhang for easy removal.
Combine Dry Ingredients
  • In a large mixing bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.
Combine Wet Ingredients
  • In a separate mixing bowl, whisk together the sugar, oil, eggs, and vanilla extract until well combined. Gradually whisk in the buttermilk until smooth.
Combine Wet and Dry
  • Pour the wet ingredients into the dry ingredients and gently fold together with a rubber spatula until just combined. Do not overmix; a few streaks of flour are okay.
Add Zucchini and Chocolate
  • Fold in the grated zucchini and chocolate chips until evenly distributed throughout the batter.
Bake
  • Pour the batter into the prepared loaf pan and spread evenly. Bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out with just a few moist crumbs attached. If the top is browning too quickly, tent it with foil after 30 minutes.
Cool and Serve
  • Let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Slice and serve. Enjoy!

Notes

For best results, use room temperature ingredients. The zucchini should be grated but not squeezed dry, as the moisture is important for the bread's texture. Store leftover bread in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. You can also freeze it for longer storage.

Pro Tips for Making This Double Chocolate Zucchini Bread

Here are a few of my favorite tips to ensure your Double Chocolate Zucchini Bread turns out perfectly every time. These tips are designed to help you avoid common mistakes and enhance the overall flavor and texture.

For Extra Flavor

To boost the chocolate flavor, I like to add a tablespoon of instant espresso powder to the dry ingredients. It enhances the cocoa and makes the chocolate taste even richer!

My Secret Trick:

Grate the zucchini and then squeeze out any excess moisture using a clean kitchen towel. This prevents the bread from becoming soggy and ensures a perfect texture. I always do this when baking with zucchini, and it makes a huge difference! This secret trick helps keep the Double Chocolate Zucchini Bread nice and fluffy.

Avoiding Common Mistakes

Make sure your baking powder and baking soda are fresh. This will help the bread rise properly and give it a light, airy texture.
