Ingredients
Complete Ingredient List

- Sugars and Oils
- Eggs and Vanilla
- Chocolate Chips and Walnuts
For these Double Chocolate Zucchini Muffins, you need some simple yet key ingredients. First, grab 1 medium zucchini. Grate it finely to mix well into the batter. Then, you need 1 cup of all-purpose flour and 1/3 cup of unsweetened cocoa powder. These form the base of your muffins and give them that rich chocolate flavor.
Next, we add sweetness and moisture. You will need 1/2 cup of granulated sugar and 1/2 cup of packed brown sugar. Combine those with 1/3 cup of vegetable oil for a nice, moist texture. To bind everything, use 2 large eggs and add 1 teaspoon of vanilla extract for extra flavor.
Don't forget the leavening agents! You want 1 teaspoon of baking soda, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt. These will help your muffins rise and taste great.
Finally, for the best double chocolate experience, use 1/2 cup of semi-sweet chocolate chips. If you like a little crunch, add 1/4 cup of chopped walnuts. This mix of ingredients creates a tasty treat that everyone will love.

Step-by-Step Instructions
Prepping the Oven and Muffin Tin
First, set your oven to 350°F (175°C). This is the perfect temperature to bake your muffins. Next, prepare a 12-cup muffin tin. You can line it with paper liners or grease it lightly with oil. This step helps prevent sticking and makes cleanup easier.
Mixing Wet Ingredients
In a medium bowl, grate one medium zucchini. You want it to be fine for even mixing. Add the grated zucchini to the bowl along with 1/3 cup of vegetable oil, 1/2 cup of granulated sugar, and 1/2 cup of packed brown sugar. Crack in 2 large eggs and add 1 teaspoon of vanilla extract. Use a whisk to mix everything until it’s smooth and well combined.
Combining Dry Ingredients
Take a larger bowl and mix together 1 cup of all-purpose flour, 1/3 cup of unsweetened cocoa powder, 1 teaspoon of baking soda, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt. Whisk until all the dry ingredients are blended and there are no lumps. This will give your muffins the right texture.
Folding Batter and Filling Muffin Cups
Now it’s time to combine the wet and dry ingredients. Gradually add the wet mix into the dry mix. Use a spatula to fold them together gently. Mix just until you see no dry flour. Be careful not to overmix; this keeps the muffins light. Next, fold in 1/2 cup of semi-sweet chocolate chips and optional 1/4 cup of chopped walnuts. This adds great flavor and texture.
Spoon the batter into each prepared muffin cup, filling them about 3/4 full. This gives the muffins room to rise without overflowing.
Baking and Cooling the Muffins
Place the muffin tin in the oven and bake for 18-22 minutes. Check for doneness by inserting a toothpick into the center of a muffin. If it comes out clean, they are ready. Once baked, let the muffins cool in the pan for 5 minutes. After that, carefully transfer them to a wire rack to cool completely. Enjoy the delightful aroma as they cool!
Tips & Tricks
How to Prevent Overmixing
To keep your muffins soft, mix just enough. When you add wet to dry, stir gently. Overmixing makes muffins tough. I like to fold until I see no flour. This keeps them fluffy and light.
Ensuring the Zucchini is Properly Grated
Grate your zucchini finely for the best texture. I use a box grater, which works well. If your zucchini is too chunky, it won’t blend in. Make sure to squeeze out extra water too. This helps keep your muffins from being soggy.
Baking Time and Toothpick Test
Baking time is key for perfect muffins. Check around 18 minutes. Insert a toothpick into the center. If it comes out clean, your muffins are done. If not, bake for a few more minutes. Remember, every oven is different!
Serving Suggestions
Serve your muffins warm for the best taste. I love to dust them with powdered sugar. Pair them with coffee or milk for a nice treat. You can also add a scoop of ice cream on top for a fun dessert!
Pro Tips
- Use Fresh Zucchini: Choose zucchini that is firm and free from blemishes for the best flavor and texture in your muffins.
- Don't Overmix: Mix the batter just until combined to ensure your muffins are light and fluffy. Overmixing can lead to dense muffins.
- Chocolate Chip Variations: Feel free to experiment with different types of chocolate chips, such as dark chocolate or white chocolate, for a unique twist.
Variations
Adding Different Mix-Ins
You can make these muffins even better by adding mix-ins. Try using nuts, like walnuts, for crunch. You can also add dried fruit, such as raisins or cranberries, for sweetness. Want more chocolate? Toss in extra chocolate chips or chunks. These little changes let you customize your muffins. Each time you bake, you can create a new flavor.
Gluten-Free Version
If you need a gluten-free option, swap all-purpose flour with a gluten-free blend. Make sure the blend has a good structure to hold everything together. You might also need to add a bit of xanthan gum to help with texture. This change makes it easy for everyone to enjoy these tasty muffins without worry.
Healthier Sugar Alternatives
To make these muffins healthier, you can use alternative sweeteners. Try coconut sugar or honey as substitutes for granulated sugar. Maple syrup can also work well, but you may need to reduce the liquid in your recipe. This way, you can enjoy the sweetness without all the refined sugar. It's a great way to keep the flavor while making a better choice.

Reheating Tips
