Ingredients You’ll Need

The magic here is combining fresh zucchini with hearty oats and gooey chocolate chips. I love how the brown sugar and maple syrup add depth of flavor and that nice balance of sweet with a touch of earthiness.

  • Shredded zucchini: Lightly blotted to keep moisture in check without drying it out completely. No need to peel!

  • Baking soda and salt: To help with rising and balance flavors.
  • Ground cinnamon: Adds cozy warmth and pairs perfectly with chocolate.
  • Unsalted butter: Softened to room temperature for creamy mixing.
  • Dark or light brown sugar: For moisture and deep flavor complexity.
  • Granulated sugar: Balances sweetness and helps set crisp edges.
  • Large egg: At room temperature to help bind ingredients.
  • Pure maple syrup: Adds subtle sweetness and helps cookies spread and crisp nicely.

  • Swap the maple syrup: Honey or molasses both work beautifully if you want a different flavor vibe.
  • Make it gluten-free: Use a gluten-free oat and flour blend to keep them safe and delicious for gluten-sensitive friends.

How to Make Zucchini Oatmeal Chocolate Chip Cookies Recipe

Step 1: Prepare the zucchini just right

Start by shredding your zucchini and lightly blotting it with a clean kitchen towel or paper towel. You don’t want to squeeze out all the moisture—just a gentle press to avoid soggy dough later. I like to shred mine with a box grater right into a bowl, then blot gently before measuring out 1 cup (130g) and setting it aside. You can even refrigerate it if you’re prepping ahead.

Step 2: Mix your dry ingredients

Whisk together your oats, flour, baking soda, salt, and cinnamon in a medium bowl. This step is important because it evenly distributes the rising agents and spices, so your cookies bake up uniform and flavorful.

Step 3: Cream butter and sugars until fluffy

Using a hand mixer or stand mixer fitted with a paddle attachment, beat your softened butter with both the brown and granulated sugars on medium speed for about 2 minutes. You want it nice and creamy to trap air, which helps your cookies rise and become tender. Then add the egg and mix on high until fully combined—scraping down the sides as you go. Follow it up with the maple syrup and vanilla extract, mixing again until everything’s smooth and glossy.

Step 4: Combine wet and dry ingredients, then add zucchini and chocolate chips

Add your dry oat mixture and that lovely shredded zucchini to the wet ingredients, then mix on low speed just until combined. Be careful not to overmix—you want the dough to be evenly mixed but still tender. While the mixer runs on low, toss in the chocolate chips and fold them through gently.

Step 5: Chill the dough – patience pays off!

I discovered this trick when the cookies wouldn’t spread properly—chilling the dough for at least 2 hours (or up to 4 days) makes all the difference. Pop it in the refrigerator to let the flavors meld and the dough firm up, which prevents excessive spreading and improves texture. If it’s been in the fridge a long time, let the dough sit at room temperature for about 30 minutes before scooping.

Step 6: Bake to golden perfection

Preheat your oven to 350°F (177°C) and line your baking sheets with parchment paper or silicone mats. Using a medium cookie scoop or your hands, place heaping tablespoon-and-a-half sized dough balls about 3 inches apart. Bake for 13 to 14 minutes. The edges should be lightly browned but the centers will look soft—that’s perfect! If you prefer crisper edges, bake 15 minutes. When they come out, let them cool on the sheet for 5 minutes, then transfer to a wire rack. Pro tip: while still warm, press a few extra chocolate chips on top—they look irresistible!

Pro Tips for Making Zucchini Oatmeal Chocolate Chip Cookies Recipe

  • Don’t over-blot the zucchini: Leaving a bit of moisture helps keep the cookie soft without making them soggy.
  • Chill your dough: This step improves dough handling and cookie texture, making them less likely to spread too much.
  • Use old-fashioned oats: Their coarser texture gives the perfect chewy bite that quick oats can’t replicate.
  • Press in chocolate chips warm: Adds a professional, bakery-style finish that looks amazing and tastes even better.

How to Serve Zucchini Oatmeal Chocolate Chip Cookies Recipe

The image shows a metal cooling rack filled with 14 round oatmeal cookies that have a rough, chunky texture mixed with small green bits and dark chocolate chips unevenly spread on top. The cookies are golden brown, slightly crispy on the edges, and soft-looking in the middle. The cooling rack is placed on a white marbled surface, with a crumpled light green cloth partially visible on the left side. The cookies are arranged closely, filling the rack in a neat pattern.

Garnishes

I usually keep it simple with these cookies, but popping a few extra chocolate chips on top right after baking makes them extra eye-catching. Occasionally, I sprinkle a tiny pinch of flaky sea salt to highlight the chocolate’s sweetness—that’s a lovely touch if you want something a bit fancy.

Side Dishes

These cookies pair wonderfully with a cold glass of milk or a cozy cup of coffee or tea. For brunch, I like serving them alongside fresh fruit or yogurt to balance their sweetness with a lighter side.

Creative Ways to Present

For gatherings, stack these cookies tied with a pretty ribbon or arrange them on a platter with some colorful fresh flowers. I’ve also wrapped individual cookies in parchment and twine for gifting, which guests always appreciate as a thoughtful homemade touch.

Make Ahead and Storage

Storing Leftovers

I keep my cookies fresh by storing them in an airtight container at room temperature, where they last beautifully for up to 5 days. If you want to stretch that, refrigeration can preserve them for a week without drying them out.

Freezing

I love freezing both the baked cookies and the dough balls. For dough, I shape them and freeze on a baking sheet, then transfer to a bag for up to 3 months. Baking from frozen just means adding an extra minute or two, no need to thaw. This is a lifesaver when I want fresh cookies fast!

Reheating

To reheat, I pop refrigerated or frozen cookies in a 300°F oven for about 5 minutes. This refreshes their softness and melts the chocolate chips nicely, almost like they’re freshly baked all over again.

FAQs

  1. Can I use peeled zucchini instead of unpeeled in this recipe?

    Absolutely! I usually leave the peel on for added fiber and color, but peeling it won’t affect the taste much—just be sure to shred and blot the zucchini well to control moisture.

  2. What kind of oats should I use for these cookies?

    Old-fashioned whole rolled oats are best here because they maintain a chewy texture and hold up well during baking. Quick oats tend to make cookies too soft and can change the structure.

  3. Can I substitute maple syrup for honey or another sweetener?

    Yes, honey or molasses work well too, though maple syrup has a unique flavor and helps with spreading and crisping edges. If you omit it entirely, just note cookies might be less spread out.

  4. How long can I refrigerate or freeze the cookie dough?

    The dough can chill in the fridge up to 4 days without issue. For longer storage, freeze dough balls up to 3 months. When ready to bake, just bake from frozen with a slightly longer time.

Final Thoughts

This Zucchini Oatmeal Chocolate Chip Cookies Recipe is one of my favorite ways to combine dessert with a bit of nutrition without sacrificing flavor or texture. I love how any time I bake these, they bring smiles and a little surprise since no one expects zucchini in such a delicious cookie. I highly recommend giving this recipe a try—you’ll feel great sneaking in veggies, and everyone gets to enjoy a soft, chewy chocolate chip cookie that’s just a bit more special.

Ingredients

Units Scale

Vegetables

  • 1 cup (130g) shredded zucchini (lightly blotted)

Dry Ingredients

  • 2 cups (170g) old-fashioned whole rolled oats
  • 1 cup (125g) all-purpose flour (spooned & leveled)
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon

Wet Ingredients

  • 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
  • 1/2 cup (100g) packed dark or light brown sugar
  • 1/2 cup (100g) granulated sugar
  • 1 large egg, at room temperature
  • 1 tablespoon pure maple syrup
  • 1 and 1/2 teaspoons pure vanilla extract

Add-Ins

  • 1 cup (180g) semi-sweet chocolate chips

Instructions

  1. Prepare Zucchini: Lightly blot the shredded zucchini with a clean kitchen towel or paper towel to remove excess moisture. Aim for about 1 cup (130g) of lightly blotted zucchini. Set aside until step 4; you can also cover and refrigerate it for up to 1 day if prepared in advance.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the old-fashioned oats, all-purpose flour, baking soda, salt, and ground cinnamon until combined. Set this dry mix aside.
  3. Cream Butter and Sugars: Using a hand mixer or stand mixer fitted with a paddle attachment, beat the softened butter along with the brown and granulated sugars on medium speed until the mixture is creamy, about 2 minutes. Then add the egg and mix on high speed until combined, around 1 minute. Scrape down the bowl as needed to ensure even mixing.
  4. Add Flavorings and Zucchini: Mix in the pure maple syrup and vanilla extract on high until fully incorporated. Then add the dry ingredient mixture and the shredded zucchini to the wet ingredients. Mix on low speed until just combined. Keep the mixer running on low and beat in the chocolate chips.
  5. Chill Dough: Cover the cookie dough and refrigerate for at least 2 hours and up to 4 days. If chilling more than a few hours, allow the dough to sit at room temperature for about 30 minutes before rolling, as it will be quite firm straight from the fridge.
  6. Preheat and Prepare Baking Sheets: Preheat your oven to 350°F (177°C). Line baking sheets with parchment paper or silicone baking mats.
  7. Form and Bake Cookies: Scoop or roll about 1.5 tablespoons of dough per cookie and place them 3 inches apart on the prepared baking sheets. Bake for 13–14 minutes until edges are lightly browned; for crispier edges, bake up to 15 minutes. The centers will appear very soft upon removal.
  8. Cool and Serve: Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. While still warm, optionally press a few extra chocolate chips on top for an attractive finish. Cookies will be soft fresh from the oven and become chewier as they cool.
  9. Storage: Store cookies covered at room temperature for up to 5 days or refrigerate for up to 1 week. Dough and baked cookies can be frozen for up to 3 months.

Notes

  • Baked cookies freeze very well for up to three months.
  • Unbaked cookie dough balls can also be frozen up to three months; bake frozen dough balls for an extra minute without thawing.
  • You can peel the zucchini before shredding if preferred, but it is not necessary.
  • Use old-fashioned whole rolled oats for the best chewy texture; avoid quick or instant oats.
  • Maple syrup helps the cookies spread and crisp the edges; it can be substituted with honey or molasses or omitted, though its inclusion is recommended.
  • Special tools that make this recipe easier include a box grater, electric mixer, medium cookie scoop, and silicone baking mats or parchment paper.
