Tips
- Be careful not to overmix—the batter will be thick, and that’s perfect!
- No need to squeeze the liquid from the zucchini before adding to the muffins since they will add needed moisture to the muffin batter.
- Mini chocolate chips allow the muffins to puff up a bit more, but regular chocolate chips can work as well.
- Easily swap the canola/vegetable oil with avocado oil for a healthier option!
- Make the muffins dairy-free by using vegan sour cream + dairy-free mini chocolate chips.
Variations for Zucchini Muffins
- Whole Wheat Zucchini Muffins: Swap out half the flour for whole wheat flour or use coconut sugar instead of granulated sugar.
- Mix-Ins & Toppings: Stir in a handful of chopped nuts, dried fruit, or shredded coconut for extra texture.
- Gluten-Free Courgette Muffins: Use a 1:1 gluten-free baking flour blend in place of all-purpose flour.
- Vegan Zucchini Muffins: Replace the eggs with flax eggs (1 tablespoon flaxseed meal + 3 tablespoons water per egg) and use a dairy-free sour cream alternative.

Keep these muffins fresh with these simple storage tips:
- Room Temperature: Store in an airtight container for up to 2 days.

Chocolate Courgette (Zucchini) Muffins
Equipment
Ingredients

- 1 cup sour cream
- 1/2 cup granulated sugar
- 2 large eggs at room temperature
- 1 1/2 teaspoons vanilla extract

- 1/2 cup dutch process cocoa powder spooned and leveled
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup mini semi-sweet chocolate chips
Instructions
- *Be sure to grate the zucchini before starting the recipe.
- Preheat the oven to 375 degrees F and line a 12-count muffin pan with paper cupcake liners. The muffins will rise a lot and touch the top of the pan, so you can spray the top of the pan with baking spray as well (if the pan isn’t nonstick).
- In a large mixing bowl add the oil, sour cream, sugar, eggs and vanilla and whisk together until combined. Mix in the grated zucchini.
- In another large bowl, whisk together the flour, baking powder, baking soda and salt.
- Add the dry ingredients to the liquid ingredients and fold with a rubber spatula until well combined.
- Fold in the mini chocolate chips. The batter should be super thick. Be careful not to overmix otherwise the batter can become too dense.
- Let the batter rest for 10 minutes to let the zucchini release its liquid. Then, mix again for 10 seconds. Be sure not to overmix!
- Divide the batter among the 12 muffin cavities.
- Bake muffins for 21-23 minutes or until a toothpick inserted into the center comes out clean.
- Allow the muffins to cool for 10 minutes before removing them from the pan and setting the muffins onto a wire rack to cool completely.
