What You Need to Gather

• 1 1/2 cups granulated sugar
• 1/2 cup packed brown sugar
• 1 cup canola or vegetable oil
• 3 eggs
• 1 tablespoon vanilla extract
• 2 1/2 cups all-purpose flour
• 1/2 cup Hershey’s special unsweetened dark cocoa powder
• 1 teaspoon cinnamon
• 1 teaspoon salt
• 1 teaspoon baking soda
• 1 cup finely grated zucchini, drained slightly
• 1 cup shredded carrots
• 1 cup semi-sweet chocolate chunks
• 1/2 cup mini semi-sweet chocolate chips (optional)

Baking the Muffins

1. Preheat oven to 350°F and line a muffin tin with paper liners or grease it well.
2. Finely grate the zucchini and shred the carrots.
3. Drain shredded zucchini in a strainer for 10–15 minutes or wrap in a clean towel/cheesecloth and gently squeeze out excess water, leaving a bit of moisture.
4. In a large bowl, combine granulated sugar, brown sugar, and oil; beat with an electric mixer until smooth.
5. Add eggs and vanilla to the sugar-oil mixture and beat until glossy and combined.
6. In a separate bowl, whisk together flour, cocoa powder, baking soda, cinnamon, and salt until evenly blended.
7. Slowly add the dry mixture to the wet ingredients, mixing just until combined—do not overmix.
8. Gently fold in the drained shredded zucchini and shredded carrots until evenly distributed.
9. Stir in the chocolate chunks.

10. Use an ice cream scoop or spoon to divide batter evenly among the prepared muffin cups.

11. Sprinkle mini chocolate chips over the tops if desired.
12. Bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean or with just a few crumbs.
13. Let muffins cool briefly before serving.

Pro Tips for Best Results

• Use measuring cups and spoons for accuracy—especially a 1/2 cup and 1 tablespoon set.
• A muffin tin and liners make baking and cleanup easy.
• A food processor with a grating attachment speeds up shredding, or grab a classic box grater.
• An ice cream scoop with a release helps portion the batter evenly and cleanly.

Serve these muffins just slightly warm alongside a bowl of fresh berries for a bright contrast. If you’re hosting brunch, they shine next to a yogurt bar or a pot of strong coffee. And the best secret? No one needs to know there’s zucchini hiding inside—unless you want all the praise!

Ways to Customize the Recipe

• Whole-wheat option: Swap up to half the all-purpose flour for whole-wheat pastry flour for a nuttier, slightly heartier muffin.
• Gluten-free: Use a 1:1 gluten-free baking blend with xanthan gum instead of all-purpose flour. Keep the same measurements and test doneness with a toothpick.
• Lower-fat option: Replace half the oil with unsweetened applesauce (i.e., 1/2 cup oil + 1/2 cup applesauce) for lighter muffins that stay moist.
• Vegan: Swap out eggs with flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water, let it gel for 5 minutes) and use dairy-free chocolate. Bake times stay similar but test for doneness.
• Flavor boosters: Add 1 teaspoon instant espresso powder to the dry ingredients to intensify the chocolate, or mix in 1 tablespoon fresh orange zest for a bright citrus twist.
• Other add-ins: Swap the chocolate chunks for milk or dark chocolate chips, fold in 1/2 cup chopped nuts like walnuts or pecans, or toss in 1/3 cup dried cherries or cranberries for a fruity pop.
• Size changes: Make mini muffins (bake 12–15 minutes) or jumbo muffins (bake 22–26 minutes). To make a loaf, pour batter into a greased 9×5-inch loaf pan and bake 45–55 minutes, checking doneness with a toothpick.
• Sweetness level: You can reduce granulated sugar up to 1/4 cup without changing texture much; cutting more will make the muffins less tender.

Storage and Freezing Guide

Freezer: Wrap muffins individually and freeze for up to 3 months. Thaw overnight in the fridge or warm gently in the microwave.

Room temperature: Keep in an airtight container for up to 2 days. Perfect if you’re eating them fast!

Refrigerator: Store covered for up to 5 days. Thanks to the veggies and oil, they’ll stay moist and delicious.

Notes

Food processor for shredding zucchini: This tool will cut your prep time in half, making the process quick and easy!

Be careful not to squeeze out all the zucchini moisture. If the zucchini is too dry, muffins turn out dry. The zucchini’s moisture is key to that soft, delicious crumb we all love.

Answers to Common Questions

• Q: How finely should I grate the zucchini?
  A: Finely grated is best, either with a box grater or your food processor’s grating attachment. Finer shreds spread evenly, keeping the muffins super tender.
• Q: Do I need to squeeze out all the moisture from the zucchini?
  A: Not all of it. Remove excess water so the batter isn’t watery, but leaving a bit of moisture helps keep the crumb moist and tender.
• Q: Can I skip the carrots?
  A: Yes. Carrots add natural sweetness and texture but aren’t required. You can leave them out and bake the muffins the same way.
• Q: How do I tell when the muffins are done?
  A: Stick a toothpick in the center; it should come out with just a few crumbs, no wet batter. Also, muffin tops spring back gently when pressed.
• Q: Can I prepare the batter ahead of time?
  A: For the best rise, combine the dry and wet ingredients separately and mix them together right before baking. You can refrigerate the mixed batter for up to 24 hours, but expect a slight drop in rise due to baking soda losing some power.
• Q: Why use oil instead of butter?
  A: Oil keeps cocoa-based baked goods moist and tender longer. Melted butter works too but results in slightly firmer muffins with a richer, buttery flavor.
• Q: How do I store and reheat leftovers?
  A: Keep muffins in an airtight container at room temp for 2 days, in the fridge for 5 days, or freeze individually wrapped for up to 3 months. Reheat gently in the microwave or oven.
• Q: Can I reduce or swap out sugar?
  A: You can cut granulated sugar by up to 1/4 cup without affecting texture too much. Switching to liquid sweeteners or sugar alternatives will change texture and may need more recipe tweaks.
• Q: Will different cocoa powders change the muffins?
  A: Yes. Natural and Dutch-processed cocoas behave differently in baking. Both work, but flavors and colors will vary slightly. No recipe changes needed unless you’re adjusting leavening for acidity.
• Q: Should I use paper liners or bake in a bare tin?
  A: Both options work. Liners make cleanup simpler, but if you use a bare tin, be sure to grease it well so muffins don’t stick.
