Ingredients

For the Muffins
- 1 cup finely grated zucchini (you’ll need about 1 small to medium zucchini)
- 1 1/2 cups all-purpose flour (187.5 grams)
- 1/2 cup cocoa powder (40 grams)
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup vegetable oil (120 ml) (or canola)
- 1/2 cup granulated sugar (100 grams)
- 1/2 cup brown sugar (100 grams) (light or dark)
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/4 cup milk (60 ml)
- 3/4 cup chocolate chips (120 grams)
How to Make Chocolate Zucchini Muffins
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C or 180°C for a forced fan oven). Line a 12-cavity muffin pan with muffin papers to prevent sticking.
Step 2: Prepare Zucchini
Using a paper towel, squeeze out any excess liquid from the grated zucchini. It won’t feel dry but shouldn’t be dripping water.
Step 3: Mix Dry Ingredients
In a medium bowl, whisk together:
1. All-purpose flour
2. Cocoa powder
3. Baking powder
4. Baking soda
5. Salt
Make sure everything is well combined.
Step 4: Combine Wet Ingredients
In a separate large bowl, whisk together:
1. Vegetable oil
2. Granulated sugar
3. Brown sugar
4. Eggs
5. Vanilla extract
6. Milk
Ensure that the eggs are fully incorporated into the mixture.
Step 5: Combine Dry and Wet Mixtures
Carefully whisk the dry ingredients into the wet ingredients until no lumps remain. The batter should be glossy and sticky.
Step 6: Add Zucchini and Chocolate Chips
Gently fold in the grated zucchini and chocolate chips using a rubber spatula until evenly distributed.
Step 7: Fill Muffin Pan
Spoon the batter into each muffin paper until they are about 3/4 full or slightly more.
Step 8: Bake Muffins
Place in the preheated oven and bake for about 20-25 minutes. They are done when the tops are rounded, and a toothpick inserted comes out clean or with a few moist crumbs attached.
Step 9: Cool Down
Allow cooling in the pan for about 10-15 minutes before transferring muffins to a wire rack to cool completely.
Now you have deliciously moist Chocolate Zucchini Muffins ready to enjoy! Perfect for sharing or savoring all by yourself!

Common Mistakes to Avoid
Making Chocolate Zucchini Muffins can be easy, but there are common pitfalls that can affect the texture and flavor. Here are some mistakes to watch out for.
- Skipping the zucchini prep: Not squeezing out excess moisture from the grated zucchini can lead to soggy muffins. Use a paper towel to remove moisture before adding it to the batter.
- Overmixing the batter: Mixing too much after adding dry ingredients can result in tough muffins. Mix just until combined for a light and fluffy texture.
- Ignoring oven temperature: Baking at the wrong temperature can ruin your muffins. Always preheat your oven to 375F (190C) for even baking.
- Not using enough chocolate chips: A common mistake is skimping on chocolate chips, which enhances flavor. Use the full 3/4 cup for deliciously rich muffins.
- Underbaking or overbaking: Baking time is crucial; check for doneness with a toothpick. If it comes out clean or with a few moist crumbs, they’re ready!
