Ingredients List for Chocolate-Zucchini Bran Muffins
- 1½ cups wheat bran
- 1 cup whole wheat flour
- ½ cup all-purpose flour
- ½ cup unsweetened cocoa powder
- 1½ teaspoons baking powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- 2 large eggs
- ⅔ cup brown sugar (can substitute with coconut sugar for a healthier option)
- ¼ cup olive oil (or unsweetened applesauce for lower fat content)
- 1 teaspoon vanilla extract
- 1 cup buttermilk (substitute with almond milk + 1 tablespoon vinegar for dairy-free)
- 1½ cups shredded zucchini (about 1 medium zucchini), excess moisture squeezed out
- ½ cup dark chocolate chips (can use mini chips for better distribution)
- ⅓ cup chopped walnuts (optional)
The key to these Healthy Zucchini-Chocolate Muffins is using fresh zucchini, which adds incredible moisture without an overwhelming vegetable taste. The combination of wheat bran and whole wheat flour delivers an impressive 5g of fiber per muffin!
Timing
- Preparation time: 15 minutes

- Total time: 35-37 minutes
This recipe takes 35% less time than traditional bran muffins, which often require resting periods for the batter. The efficiency makes these perfect for busy mornings or meal prep sessions!

Step-by-Step Instructions for Chocolate-Zucchini Bran Muffins
Step 1: Prepare Your Ingredients and Equipment
Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or spray with non-stick cooking spray. Measure all ingredients and have them ready. Grate the zucchini and place it in a clean kitchen towel to squeeze out excess moisture – this prevents soggy muffins!
Step 2: Mix Dry Ingredients
In a large bowl, whisk together the wheat bran, whole wheat flour, all-purpose flour, cocoa powder, baking powder, baking soda, and salt. Breaking up any cocoa powder clumps ensures even chocolate distribution and prevents bitter pockets in your finished muffins.
Step 3: Combine Wet Ingredients
In a separate medium bowl, beat the eggs until frothy (about 30 seconds), then add brown sugar and beat until well combined. Add the oil, vanilla extract, and buttermilk, whisking until smooth. The frothy egg mixture creates a lighter texture in the final product!
Step 4: Combine Wet and Dry Mixtures
Make a well in the center of your dry ingredients and pour in the wet mixture. Stir gently just until combined – overmixing activates gluten and results in tough muffins. You want to see the flour just disappear into the batter, with a few small lumps remaining.
Step 5: Fold in Zucchini and Chocolate
Gently fold in the shredded zucchini and chocolate chips (and nuts if using) until evenly distributed. The moisture from the zucchini will loosen the batter slightly, which is perfect for moist muffins.
Step 6: Bake to Perfection
Fill each muffin cup about ¾ full. Bake for 20-22 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs. For even baking, rotate the pan halfway through cooking time.
Step 7: Cool and Enjoy
Allow muffins to cool in the pan for 5 minutes before transferring to a wire rack to cool completely. This resting period allows the muffins to set properly and enhances their flavor profile.

FAQs
Can I make these muffins gluten-free?
Yes! Substitute the wheat bran with oat bran and use a 1:1 gluten-free flour blend in place of the wheat flours. Add ¼ teaspoon xanthan gum if your blend doesn’t already contain it.
How can I make these muffins vegan?
Replace eggs with 2 flax eggs (2 tablespoons ground flaxseed mixed with 6 tablespoons water), use plant-based milk with vinegar instead of buttermilk, and ensure your chocolate chips are dairy-free.
Can I use yellow squash instead of zucchini?
Absolutely! Yellow summer squash works perfectly as a 1:1 substitute for zucchini in this recipe, with virtually no difference in taste or texture.
My kids don’t like vegetables. Will they taste the zucchini?
The cocoa powder and chocolate chips effectively mask the zucchini flavor. Most children (and picky adults!) can’t detect the vegetable in these muffins.
Can I make this as a loaf instead of muffins?
Yes! Pour the batter into a greased 9×5-inch loaf pan and bake at 350°F for 45-55 minutes, or until a toothpick inserted in the center comes out clean.
