Ingredients and Measurements

• 1½ cups grated zucchini (measure before squeezing moisture out)
• 2 large eggs
• ¼ cup avocado oil (or olive oil)
• ⅓ cup maple syrup
• 2 teaspoons vanilla extract
• ⅔ cup unsweetened applesauce
• 1¼ cups whole wheat flour
• ¼ cup unsweetened cocoa powder
• ½ teaspoon baking soda
• 1 teaspoon baking powder
• 1 teaspoon cinnamon
• ½ teaspoon salt
• ⅓ cup chocolate chips, plus extra for topping

How to Make Them

1. Preheat oven to 375°F and line a 12-hole muffin tin.
2. Place shredded zucchini in the center of a clean kitchen towel or paper towels.
3. Wrap zucchini and squeeze firmly to remove as much moisture as possible.
4. Transfer drained zucchini to a large mixing bowl and add eggs, avocado or olive oil, maple syrup, vanilla, and applesauce; whisk until combined.
5. Add whole wheat flour, cocoa powder, baking soda, baking powder, cinnamon, and salt to the wet ingredients.
6. Gently stir with a spoon or spatula until the dry ingredients are just incorporated, taking care not to overmix.
7. Fold in chocolate chips until evenly distributed.

8. Divide batter evenly among prepared muffin cups, filling each about three-quarters full; sprinkle extra chocolate chips on top if desired.

9. Bake 18–20 minutes, or until a toothpick inserted in the center comes out mostly clean (or muffins reach about 200°F internal temperature).
10. Let muffins cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.

Baker’s Tips for Best Results

• Make sure you squeeze the zucchini well to avoid a soggy batter. I love wrapping it up in a clean towel and pressing firmly until most of the water is gone.
• Don’t overmix the batter! Stop stirring as soon as all the flour disappears. This little trick keeps your muffins soft and fluffy.
• When measuring flour, spoon it into your cup and level it off. Scooping directly from the bag can pack too much flour in, making muffins denser.
• If you’ve got a kitchen thermometer, try pulling the muffins when they hit 200°F inside. This nails perfect doneness with moist centers.
• Fold chocolate chips into the batter gently. For a pretty finish, press a few extra chips on top of each muffin before baking.
• If you want your muffins less sweet, cut back slightly on the maple syrup or choose darker chocolate chips to balance the sweetness.

Flavor Swaps and Add-Ins

• Swap the applesauce for ⅔ cup mashed ripe banana if you want a natural sweetness with a hint of banana flavor. I do this often and love the extra moisture.
• Feel free to swap all the whole wheat flour for all-purpose flour if you prefer a lighter crumb, or split half and half for a milder whole-grain taste.
• Add ¼ to ⅓ cup chopped walnuts or pecans for a lovely crunchy surprise inside your muffins.
• You can switch up the chocolate chips too: try white chocolate, peanut butter chips, or a mix of semi-sweet and dark chocolate for variety.
• For an extra depth of flavor, add ½ teaspoon espresso powder to boost the chocolate or 1 teaspoon orange zest to brighten things up.
• If you want, bake this batter as a loaf instead of muffins—just increase the bake time and check for doneness. Mini muffins are also fun and bake faster, usually a few minutes less.

Storage and Make-Ahead Advice

Store cooled muffins in an airtight container at room temperature if you plan to eat them within 2 days. Perfect grab-and-go snack!

If you want them to last longer, keep muffins in the fridge for 4–5 days in an airtight container. This keeps them fresh and tasty.

To freeze, line a baking sheet with muffins and freeze them in a single layer until firm. Then move to a freezer bag or container for up to a month. When ready, thaw at room temperature or warm for 15–30 seconds in the microwave.

When reheating, pop a single muffin in the microwave for 15–30 seconds or warm gently in a 325°F oven for around 5–7 minutes to bring back that fresh-baked taste.

Want to make these muffins even easier? Freeze the batter in muffin liners in the pan! When you’re ready, thaw the tin briefly in the fridge and bake as usual—just add a few extra minutes to the bake time since the batter will be chilled.

Common Questions Answered

• Do these muffins taste like zucchini? Not at all! The zucchini mainly adds moisture and boosts nutrition. Thanks to the cocoa and chocolate chips, the muffins come out deliciously chocolatey with just a subtle veggie hint.
• Can I make these vegan? Absolutely! Replace the eggs with flax eggs (2 tablespoons ground flaxseed mixed with 6 tablespoons water, chilled) and make sure your chocolate chips are dairy-free.
• Can I use a different flour? You can substitute all-purpose flour 1:1 for whole wheat if you want a lighter texture. Gluten-free blends might work, but results will vary, so experiment!
• How do I prevent soggy bottoms? Squeezing out the zucchini’s moisture well and baking fully are key. Also, using a light-colored muffin tin and greasing or lining it helps muffins bake evenly.
• Can I reduce the sweetener? Yes, reduce maple syrup a bit or add a few more chocolate chips to keep sweetness where you want it without losing moisture.
• Why use both baking soda and baking powder? Baking soda reacts with acidic ingredients like applesauce to help the muffins rise, while baking powder provides extra lift and a tender crumb.
