How to Make Zucchini Oatmeal Chocolate Chip Cookies Recipe

Step 1: Prep Your Zucchini with Care

Shred your zucchini using a box grater or food processor, then gently blot it with a clean kitchen towel or paper towels. You don’t want to squeeze out all the moisture because that’s part of what keeps the cookies soft and chewy—but blotting prevents the dough from becoming too wet. I learned this the hard way on my first try when I got soggy cookies, so trust me, this step is key!

Step 2: Mix Your Dry Ingredients

Whisk together the oats, all-purpose flour, baking soda, salt, and cinnamon in a medium bowl. This keeps your flavors and leavening agents evenly distributed, helping each cookie turn out perfectly balanced.

Step 3: Cream Butter and Sugars

Using a hand mixer or stand mixer with a paddle attachment, beat the softened butter with both sugars on medium speed until creamy—about 2 minutes. Then add the egg and beat on high until combined fully. Don’t skip scraping down the bowl sides; it ensures everything blends evenly.

Step 4: Add Wet Flavors and Combine

Mix in the maple syrup and vanilla extract until combined, then add the dry ingredients and the shredded zucchini. Mix everything on low speed just until combined. With the mixer still running, beat in the chocolate chips. At this point, your dough will be thick and deliciously speckled with chocolate.

Step 5: Chill the Dough for Best Results

Cover your dough and chill it in the refrigerator for at least 2 hours, or up to 4 days. This chilling step is crucial because it helps the flavors meld and the dough firm up for easier scooping. If you chill it longer, just let it warm up at room temp for about 30 minutes before baking.

Step 6: Bake to Golden Perfection

Preheat your oven to 350°F (177°C) and line your baking sheets with parchment or silicone mats. Scoop heaping tablespoons (about 1.5 Tbsp) of dough onto the sheet, spacing cookies about 3 inches apart. Bake for 13–14 minutes until edges are lightly browned but centers still look soft. For crispier edges, add an extra minute or two.

Step 7: Cool and Enjoy

Let your cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. While still warm, I like to press a few extra chocolate chips on top—it’s a little flourish that gets compliments every time. These cookies are soft fresh out of the oven but develop a nice chewy texture as they cool.

Pro Tips for Making Zucchini Oatmeal Chocolate Chip Cookies Recipe

  • Don’t Over-Dry the Zucchini: I found gently blotting the zucchini is better than squeezing it—it keeps just enough moisture without sogginess.
  • Chill the Dough Thoroughly: Chilling makes scooping easier and the cookies hold their shape without spreading too much.
  • Use Medium Cookie Scoop: Using a medium cookie scoop ensures even-sized cookies that bake uniformly—trust me, consistency matters!
  • Press Chocolate Chips for Looks: Adding extra chips on top while warm gives cookies a gorgeous, melty finish that’s very inviting.

How to Serve Zucchini Oatmeal Chocolate Chip Cookies Recipe

A metal cooling rack holds fifteen round oatmeal chocolate chip cookies with a golden brown color and a rough texture from the oats, each cookie dotted with dark brown chocolate chips and small green flecks, possibly zucchini. The rack is placed on a white marbled surface with a soft green cloth casually draped underneath the bottom left corner, adding a subtle color contrast to the scene. photo taken with an iphone --ar 4:5 --v 6.1

Garnishes

I usually keep it simple with some extra chocolate chips pressed on top right after baking—because who can resist that melty chocolate appeal? Occasionally, a light dusting of powdered sugar adds a pretty touch for special occasions.

Side Dishes

This cookie pairs wonderfully with a glass of cold milk or a warm cup of coffee or tea. For a sweet breakfast twist, try serving alongside yogurt topped with fresh berries—you’ll love how all those flavors come together.

Creative Ways to Present

I’ve had success stacking these cookies in cute mason jars or wrapping them individually in parchment tied with twine for gifting. For holidays, adding a drizzle of melted dark chocolate or a sprinkle of sea salt really elevates their look and taste.

Make Ahead and Storage

Storing Leftovers

Leftover cookies store beautifully in an airtight container at room temperature for up to 5 days. I find adding a slice of bread helps keep them soft longer. If you want to keep them a bit beyond that, refrigerating up to one week works well too.

Freezing

I often freeze baked cookies in freezer bags for up to three months. This recipe also freezes well as dough balls—just scoop, freeze on a baking sheet, then transfer to a bag. When you’re ready, bake frozen dough for an extra minute without thawing for fresh-baked goodness anytime.

Reheating

To reheat leftover cookies, I pop them in a preheated oven at 300°F for about 5 minutes or microwave for 10-15 seconds. This gives them that fresh-baked softness again without drying them out.

FAQs

  1. Can I use grated zucchini without removing moisture?

    It’s important to lightly blot grated zucchini with paper towels or a clean dish towel to remove excess moisture. Squeezing it too much can make the cookies dry, but leaving it wetter can result in soggy dough. Blotting gently strikes the perfect balance for soft, moist cookies.

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

    Old-fashioned whole rolled oats are best for this recipe because they give the cookies a hearty, chewy texture. Avoid quick or instant oats since they break down too much and affect the cookie’s structure and bite.

  3. Can I make these cookies vegan or dairy-free?

    Yes! You can swap the butter for a plant-based alternative and use a flax or chia egg instead of a chicken egg. Just keep in mind that these swaps might slightly affect texture, so adding a bit of extra moisture or binding agent may be helpful.

  4. How do I store the dough before baking?

    The dough keeps well covered in the fridge for up to 4 days. Before baking, allow it to rest at room temperature for about 30 minutes if it feels too firm to scoop.

Final Thoughts

This Zucchini Oatmeal Chocolate Chip Cookies Recipe has quickly become one of my go-to treats whenever I want something delicious with a little nutritious twist. It’s the kind of baked good you can feel good about sharing, and the way the zucchini melts into the dough for that perfect texture never ceases to impress me. I can’t wait for you to bake a batch yourself—your kitchen will smell amazing and your cookie jar will thank you!

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 the zucchini: Lightly blot the shredded zucchini with a clean kitchen towel or paper towel to remove excess moisture. You only need to gently blot—there’s no need to squeeze all the water out. Measure 1 cup (130g) of the shredded zucchini and set it aside until step 4. You can also cover and refrigerate it for up to 1 day before use.
  2. Mix dry ingredients: In a medium bowl, whisk together the old-fashioned oats, all-purpose flour, baking soda, salt, and ground cinnamon. Set aside for later use.
  3. Cream butter and sugars: Using a hand mixer or stand mixer with paddle attachment, beat the softened butter, dark or light brown sugar, and granulated sugar on medium speed until the mixture is creamy and well combined, about 2 minutes.
  4. Add egg, maple syrup, and vanilla: Add the large egg to the butter and sugar mixture and beat on high speed until fully incorporated, about 1 minute. Scrape down the sides and bottom of the bowl as needed. Then add the maple syrup and vanilla extract, mixing on high speed until combined.
  5. Combine wet and dry ingredients: Add the dry ingredient mixture and the shredded zucchini to the wet ingredients. Mix on low speed until just combined. While mixing on low, fold in the semi-sweet chocolate chips until evenly distributed throughout the dough.
  6. Chill the dough: Cover the cookie dough and refrigerate it for at least 2 hours and up to 4 days. For longer chilling, allow the dough to sit at room temperature for at least 30 minutes before scooping and baking, as it may become quite hard.
  7. Preheat oven and prepare baking sheets: Preheat your oven to 350°F (177°C). Line baking sheets with parchment paper or silicone baking mats to prevent sticking and ensure even baking.
  8. Shape and bake cookies: Scoop or roll heaping 1.5 tablespoon portions of dough per cookie using a medium cookie scoop. Place the dough balls 3 inches apart on the prepared baking sheets. Bake in the preheated oven for 13-14 minutes until the cookie edges are lightly browned. For crispier edges, bake up to 15 minutes.
  9. Cool and finish: Remove the cookies from the oven and allow them to cool on the baking sheets for 5 minutes. For an extra chocolatey look, press a few additional chocolate chips into the top of each warm cookie. Then transfer cookies to a wire rack to cool completely. The cookies will be soft out of the oven and become chewier as they cool.
  10. Storage: Store cookies covered at room temperature for up to 5 days or refrigerate for up to 1 week. For longer storage, freeze baked cookies or unbaked dough balls for up to 3 months.

Notes

  • Baked cookies and unbaked cookie dough balls freeze well for up to three months. To bake from frozen, simply add an extra minute to the baking time without thawing.
  • The author recommends old-fashioned whole rolled oats for the best chewy texture; avoid using quick or instant oats.
  • The zucchini does not need to be peeled before shredding, but peeling is optional based on preference.
  • Maple syrup enhances flavor and helps cookies spread and crisp at the edges, but it can be substituted with honey or molasses or omitted if desired.
  • Special kitchen tools recommended include a box grater, mixing bowls, whisk, electric mixer, baking sheets, silicone baking mats or parchment paper, a medium cookie scoop, and a cooling rack.
