Zucchini Oatmeal Cookies (The Best Way to Hide Veggies)

I made these zucchini oatmeal cookies at 9 AM on a Tuesday because my neighbor left another baseball-bat-sized squash on my porch, and baking another loaf of bread felt genuinely offensive. I needed a distraction, and I wanted chocolate for breakfast.

I once dumped raw shredded zucchini into ordinary cookie dough, which created a puddle of sweet, swampy sadness that my dog refused to touch. This time, I followed the blotting rule and created soft centers, chewy oats, crisp edges, and melted chocolate chips instead. If you need an easy way to use up zucchini in cookies without crying over your baking sheet, this recipe has your back.

Tools You’ll Need

Nothing fancy, I promise.

• Clean kitchen towel: Use it to blot away excess zucchini moisture.

Ingredients

• 1 cup shredded zucchini – Lightly blotted; do not skip this or you will bake a puddle.
• 2 cups old-fashioned whole rolled oats – Not instant, we want texture here.
• 1 cup all-purpose flour – Spooned and leveled so they do not turn into hockey pucks.
• 1/2 teaspoon baking soda – For that little bit of lift.
• 1/2 teaspoon salt – To balance the sugar.
• 1 teaspoon ground cinnamon – Makes it smell like fall even if it is July.
• 1/2 cup unsalted butter – Softened to room temperature, seriously, do not melt it.
• 1/2 cup packed dark or light brown sugar – Dark gives it a richer vibe.
• 1/2 cup granulated sugar – Standard sweet stuff.
• 1 large egg – Room temperature if you have the patience.
• 1 Tablespoon pure maple syrup – Helps the edges crisp up, trust me.
• 1 and 1/2 teaspoons pure vanilla extract – Measure with your heart.
• 1 cup semi-sweet chocolate chips – Because these are zucchini chocolate chip cookies, not a punishment.

How To Make Zucchini Oatmeal Cookies

Do not let the green shreds intimidate you, the chocolate chips are here to save the day.

1. Prep the zucchini: Lightly blot the shredded zucchini with a clean kitchen towel or paper towel. No need to squeeze out all the moisture; gently blotting is plenty. You need 1 cup (130g) of shredded, lightly blotted zucchini. Set aside until step 4. (Or cover and refrigerate for up to 1 day. It can be cold when you add it to the dough.) If you squeeze it completely dry like I did the first time, your cookies will be sad and crumbly, so just a gentle pat is fine.
2. Mix the dry ingredients: Whisk the oats, flour, baking soda, salt, and cinnamon together in a medium bowl. Set aside. If a little flour poofs out onto your counter, just wipe it up before anyone notices.
3. Cream butter and sugar: Using a hand mixer or a stand mixer fitted with paddle attachment, beat the softened butter and both sugars together on medium speed until creamy, about 3 minutes. Do not rush this; it should look pale and fluffy, not like wet sand.
4. Add wet ingredients: Add the egg and mix on high until combined, about 1 minute. Scrape down the sides and bottom of the bowl as needed. Add the maple syrup and vanilla and mix on high until combined. The maple syrup is the secret weapon for crispy edges, so do not skip it.
5. Combine and chill: Add the dry ingredients and the zucchini to the wet ingredients, then mix on low speed until combined. With the mixer still running on low speed, beat in the chocolate chips. Cover and chill the dough in the refrigerator for at least 2 hours (and up to 4 days). If chilling for longer than a few hours, allow to sit at room temperature for at least 30 minutes before rolling and baking because the dough will be quite hard. I once skipped the chilling step because I was impatient, and they spread into one giant mega-cookie; give it the full two hours.
6. Prep for baking: Preheat oven to 350°F (177°C). Line baking sheets with parchment paper or silicone baking mats. Set aside. Silicone mats are great here because sticky dough is a nightmare to scrape off bare metal.
7. Scoop and bake: Scoop or roll cookie dough, a heaping 1.5 Tablespoons of dough per cookie (I like to use this medium cookie scoop), and place 3 inches apart on the baking sheets. Bake for 13-14 minutes or until lightly browned on the sides. The centers will look very soft. For crispier edges, bake for 15 minutes. They will look dangerously underbaked in the center when you pull them out, but they set up as they cool, I promise.
8. Cool and set: Remove from the oven and allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. While the cookies are still warm, I like to press a few more chocolate chips into the tops– this is only for looks! Cookies are extra soft out of the oven, but become chewier as they cool. Pressing extra chips on top while warm is totally unnecessary but makes you look like you know what you are doing.

Make It Yours

You can replace half the chocolate chips with chopped walnuts when you want a less sweet version of these healthy zucchini cookies. You can add raisins if you enjoy them, although I will judge you a little.

You can also add a pinch of nutmeg for a warmer spice profile. These oatmeal cookies with vegetables still taste like a proper cookie because the maple syrup, brown sugar, and chocolate chips carry the flavor.

Perfect Pairings

These go perfectly with:

• A cold glass of milk, obviously.
• Morning coffee, because oatmeal makes cookies count as breakfast.
• A late-night Netflix binge when you want chocolate but feel vaguely guilty about your vegetables.
• A school lunchbox when you want to disguise green food as dessert.

Equipment

• Box grater
• Medium cookie scoop
• Clean kitchen towel

Method

 

1. Prep the Zucchini

   You lightly blot the shredded zucchini with a clean kitchen towel or paper towel. You should not squeeze out all the moisture because the cookies can turn dry and crumbly.

   You need one cup of lightly blotted zucchini. You can cover it and refrigerate it for up to one day before mixing.
2. Mix the Dry Ingredients

   You whisk the oats, flour, baking soda, salt, and cinnamon together in a medium bowl. You set the bowl aside.
3. Cream the Butter and Sugar

   You beat the softened butter and both sugars with a hand mixer or stand mixer for about three minutes. The mixture should look pale and fluffy instead of wet and sandy.
4. Add the Wet Ingredients

   You add the egg and mix until combined. You scrape down the bowl, then add the maple syrup and vanilla.

   You mix until the batter looks smooth.
5. Combine and Chill

   You add the dry ingredients and zucchini to the wet ingredients. You mix on low speed until combined, then beat in the chocolate chips.

   You cover the dough and chill it for at least two hours and up to four days.

   If you chill the dough for more than a few hours, you let it sit at room temperature for 30 minutes before scooping.
6. Prep for Baking

   You preheat the oven to 350°F. You line the baking sheets with parchment paper or silicone baking mats.
7. Scoop and Bake

   You scoop heaping one-and-a-half-tablespoon portions and place them three inches apart on the baking sheets.

   You bake the cookies for 13 to 14 minutes until the sides turn lightly brown. You bake them for 15 minutes when you want crispier edges.

   The centers will look very soft when you remove the cookies, but they set as they cool.
8. Cool and Set

   You cool the cookies on the baking sheet for five minutes. You transfer them to a wire rack afterward.

   You can press extra chocolate chips into the warm tops for a bakery-style finish.

Recipe Notes

Make Ahead & Freezing:
Freeze baked cookies or unbaked dough balls for up to 3 months. Bake frozen dough balls without thawing, adding 1 extra minute to the bake time.

Zucchini:
No need to peel the zucchini before shredding, but you can peel it if preferred.

Oats:
Use old-fashioned whole oats for the best thick, hearty, and chewy texture. Avoid quick or instant oats.

Maple Syrup:
Maple syrup adds flavor and helps the cookies spread and crisp around the edges. You can substitute honey or molasses, or leave it out, though the cookies will have a different texture and flavor.
