Ingredients you will need to make double chocolate zucchini muffins
- Flour. All purpose flour that has been properly spooned and leveled when measured.
- Unsweetened Cocoa Powder. A better quality cocoa powder can add better flavor.
- Baking Powder and Baking Soda. The leaveners used in this recipe.
- Instant Espresso Powder Helps to bring out the chocolate flavor in these muffins.
- Sugar Alternative. Use a granular sugar alternative that measures like sugar and that can also be baked with.
- Eggs. Large eggs that are at room temperature.
- Oil. Use a neutral oil such as vegetable oil.
- Greek Yogurt. Use 'plain' yogurt that has no added sugar. Yogurt adds moisture and help in the leavening process to make these muffins even more fluffy.
- Vanilla Extract. For a bit of flavor balance to the muffins.
- Zucchini. Your zucchini should be shredded fine (no need to drain!).
- Sugar Free Chocolate Baking Chips. You can use additional chips for topping the muffins with.
Expert Tip ๐ Sour cream, regular plain yogurt, or cream cheese can be used instead of the Greek yogurt. Not that these alternatives may affect the texture of the muffins.

Tips for making the best chocolate chip muffins.
The zucchini is shredded rather than grated to allow it to disappear into the batter when baked. Shredded zucchini also helps with even moisture distribution without large chunks of zucchini (key for moms wanting to sneak in zucchini!).
More helpful tips for you.
- When combining your wet and dry ingredients, mix until just combined. Over-mixing the ingredients will activate the gluten in the flour resulting in tough and not fluffy chewy muffins.
- Your dairy (eggs and yogurt) should be at room temperature for optimal blending.
- When doing the toothpick test for doneness, keep in mind that melting chocolate chips can five you a 'false negative' result. This is why it is a good idea to test more than one muffin and in an area where there are no visible chocolate chips.
How to store zucchini muffins.
Once your muffins have fully cooled they can be stored in an airtight container. When properly stored, zucchini muffins should keep for for up to three days at room temperature, refrigerated with a paper towel for up to a week, or frozen individually for up to a few months.
