Introduction
These Ultra Moist Chocolate Zucchini Muffins are a delightful treat that combines rich chocolate flavor with the subtle sweetness and moisture of zucchini. Perfect for a breakfast snack or an afternoon indulgence, this one-bowl recipe is simple to make and yields wonderfully soft muffins.

Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 3/4 cup unsweetened cocoa powder
- 1 1/2 cups granulated sugar
- 2 large eggs
- 1/2 cup vegetable oil
- 1/2 cup plain Greek yogurt
- 2 teaspoons vanilla extract
- 1 1/2 cups grated zucchini, squeezed dry
- 1 cup semi-sweet chocolate chips
Instructions
- Step 1: Preheat your oven to 375 degrees F (190 degrees C). Line a 12-cup muffin tin with paper liners or grease the cups well.
- Step 2: In a large bowl, whisk together the flour, baking soda, baking powder, salt, and cocoa powder until evenly combined.
- Step 3: Add the sugar to the dry ingredients and whisk briefly to blend everything together.
- Step 4: Add the eggs, vegetable oil, Greek yogurt, and vanilla extract to the bowl. Use a spatula to mix until just combined; avoid overmixing to keep the muffins tender.
- Step 5: Gently fold in the squeezed, grated zucchini and the chocolate chips until they are evenly distributed throughout the batter.
- Step 6: Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full to allow room for rising.
- Step 7: Bake for 18 to 22 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs.
- Step 8: Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Tips & Variations
- Make sure to squeeze out excess moisture from the zucchini using a clean kitchen towel or cheesecloth to prevent soggy muffins.
- For extra texture, try adding chopped nuts like walnuts or pecans to the batter along with the chocolate chips.
- Substitute Greek yogurt with sour cream or buttermilk if desired for a slightly different tang.
- If you prefer less chocolate, reduce the chocolate chips to 1/2 cup or omit them entirely for a deeper cocoa flavor.
Storage
Store the muffins in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to 1 week or freeze for up to 3 months. To reheat, warm in the microwave for 15-20 seconds or until heated through.

FAQs
Can I use zucchini without peeling it?
Yes, you can grate zucchini with the skin on. The skin adds color and nutrients, and will soften during baking.
Do I need to peel the zucchini before grating?
Peeling is not necessary unless the skin is very thick or tough. Young zucchini typically have tender skins that work well in the muffins.

Ingredients
Dry Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 3/4 cup unsweetened cocoa powder
- 1 1/2 cups granulated sugar

- 1/2 cup vegetable oil
- 1/2 cup plain Greek yogurt
- 2 teaspoons vanilla extract
Add-ins
- 1 1/2 cups grated zucchini, squeezed dry
- 1 cup semi-sweet chocolate chips
Instructions
- Preheat oven and prepare pan: Heat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease the cups well to prevent sticking.
- Combine dry ingredients: In a large bowl, whisk together the all-purpose flour, baking soda, baking powder, salt, and unsweetened cocoa powder to distribute all dry ingredients evenly.
- Add sugar to dry mix: Stir the granulated sugar into the dry mixture and whisk briefly to fully combine the sugar with the dry ingredients.
- Add wet ingredients: Crack in the eggs, pour in vegetable oil, Greek yogurt, and vanilla extract. Mix gently with a spatula just until the batter comes together without overmixing to keep your muffins tender.
- Incorporate zucchini and chocolate chips: Fold the well-drained grated zucchini and semi-sweet chocolate chips into the batter until they are evenly spread throughout.
- Fill muffin cups: Spoon the batter into the prepared muffin tin, filling each cup about two-thirds full to allow room for rising.
- Bake: Place the muffin tin in the preheated oven and bake for 18 to 22 minutes. Check doneness by inserting a toothpick into the center; it should come out clean or with just a few moist crumbs attached.
- Cool muffins: Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely before serving to ensure perfect texture and flavor.
