Description

A rich, moist chocolate zucchini bread made with sour cream, combining garden‐fresh zucchini, cocoa, and chocolate chips for a deeply chocolatey quick loaf.


Ingredients

  • 1 cup plain flour
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt (fine sea or table)
  • 2 large room temperature eggs
  • 1/4 cup vegetable oil (or canola or melted coconut oil)
  • 1/3 cup sour cream (or substitute with Greek yogurt)
  • 1/4 cup white sugar
  • 1/2 cup packed light brown sugar
  • 1 teaspoon vanilla essence
  • 1 1/2 cups tightly packed finely grated zucchini
  • 1 cup semi‐sweet chocolate chips (split for use)

Instructions

  1. Preheat your oven to 325°F (163°C). Grease a 9×5‑inch loaf pan and line it with parchment paper to ensure easy removal after baking.
  2. In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.
  3. In a large bowl, combine the eggs, oil, sour cream, white sugar, brown sugar, and vanilla extract. Mix until smooth and well‑blended.
  4. Stir the dry ingredients into the wet ingredients gradually, being careful not to overmix.
  5. Fold in the grated zucchini and **¾ cup** of the chocolate chips until everything is just combined.
  6. Pour the batter into the prepared loaf pan, spreading it out evenly. Sprinkle the remaining **¼ cup** chocolate chips over the top.
  7. Bake for 55 to 65 minutes, until a toothpick inserted into the center comes out mostly clean (some melted chocolate chips are okay). If the top browns too fast, loosely cover with foil.
  8. Let the bread cool in the pan for about 15 minutes, then remove it and finish cooling on a wire rack until slightly warm before slicing.

Notes

  • You can substitute plain flour with whole wheat flour (bread will be denser), or use a 1‑to‑1 gluten‑free flour blend.
  • Greek yogurt can replace sour cream in equal amount; plain yogurt can also be used if strained.
  • Use any kind of chocolate chips (milk, dark, or white), or chopped chocolate; toss chips in a bit of flour before folding in to keep them from sinking.
  • You can use yellow summer squash instead of zucchini (color may vary).
  • Do not squeeze out all moisture from grated zucchini—some moisture helps texture, but remove excess to avoid overly wet loaf.
  • Do not overmix after adding flour to avoid a tough texture.
  • Cool completely (at least an hour) before slicing for clean cuts.
  • Storage: room temperature for up to 3 days; refrigerate up to a week; slices can be frozen up to 3 months.
