Key Ingredients for Healthy Double Chocolate Zucchini Muffins

See recipe card below for full list of measurements, ingredients, and instructions.

Zucchini

Zucchini is the secret superstar here, making these muffins exceptionally moist and tender. Be sure to finely grate your zucchini, and squeeze out any excess liquid with a clean towel-this prevents soggy muffins. No need to peel them! You can use yellow squash as a substitute, though it may change the color slightly.

Unsweetened Cocoa Powder

Cocoa powder brings deep, satisfying chocolate flavor to every bite. Use natural or Dutch-process, depending on your preference. Dutch-process will deliver a slightly darker, richer muffin. If you're out, carob powder can work, but the flavor will be different.

Applesauce

Unsweetened applesauce acts as a natural sweetener and helps keep the muffins light and moist without extra oil. If you don't have applesauce, you can use mashed banana (for a hint of banana flavor) or even Greek yogurt for extra protein.

Whole Wheat Flour

Whole wheat flour adds a nutty flavor and boosts the fiber content, making these muffins extra hearty and filling. You can substitute with all-purpose flour if you prefer lighter muffins, or use a 1:1 gluten-free flour blend for a gluten-free option.

Mini Chocolate Chips

Mini chocolate chips ensure every bite has a pop of melted chocolate! Dark, semisweet, or dairy-free chips all work well. Regular-sized chips are fine, but minis distribute more evenly.

Instructions for Healthy Double Chocolate Zucchini Muffins

See recipe card below for full list of measurements, ingredients, and instructions.

Prep Your Zucchini

Grate the zucchini on the fine side of a box grater. Use a clean kitchen towel or paper towels to squeeze out as much moisture as you can-this keeps your muffins from turning gummy.

Mix the Wet Ingredients

In a large mixing bowl, whisk together the applesauce, honey, Greek yogurt, milk, oil, egg, and vanilla extract until smooth and well combined.

Combine the Dry Ingredients

In a separate bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt. Make sure there are no lumps, especially in the cocoa powder.

Bring It All Together

Add the dry ingredients to the wet ingredients and stir gently with a spatula until just combined. Do not overmix! Fold in the grated zucchini and mini chocolate chips until evenly distributed.

Fill and Bake

Divide the muffin batter evenly among 12 greased or lined muffin cups, filling each about ¾ full. Sprinkle a few extra chocolate chips on top if you like.

Bake at 350°F (175°C) for 20-22 minutes, or until a toothpick inserted in the center comes out mostly clean (a few moist crumbs are okay).

Cool and Enjoy

Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Enjoy warm or at room temperature!

Recipe Variations

Make Them Vegan

Swap the egg for a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water), use a dairy-free yogurt, and choose plant-based milk and chocolate chips to keep these muffins completely vegan. They'll still turn out perfectly moist and delicious!

Gluten-Free Option

Replace the whole wheat flour with your favorite 1:1 gluten-free baking blend. Double-check that your other ingredients are certified gluten-free and bake as instructed.

Nutty Twist

Stir in ⅓ cup chopped walnuts or pecans for extra crunch and nutty flavor. You can also sprinkle nuts on top for a pretty finish.

Add Spice

A pinch of cinnamon or a dash of espresso powder in the batter will enhance the chocolate's richness and add a subtle depth of flavor.

Lower Sugar Swap

Replace half the honey or maple syrup with an extra ¼ cup of unsweetened applesauce for lighter sweetness and lower sugar content.

Serving Suggestions

These muffins are delicious with a dollop of Greek yogurt or a smear of almond butter for extra protein. Pair them with a cup of coffee or a smoothie for a balanced breakfast, or serve as a satisfying afternoon snack. For a fun twist, dust lightly with powdered sugar or add fresh berries on the side!

Storage and Reheating

Store cooled muffins in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate up to 1 week. To freeze, wrap individually and place in a freezer-safe bag for up to 2 months. Reheat in the microwave for 20-30 seconds to refresh their softness, or thaw overnight in the fridge.
