Ingredients You Need
Dry ingredients
-
1 ½ cups (190 g) all-purpose flour
- Use unbleached if possible for better flavor.
- You can swap half with white whole wheat flour for a nuttier taste.
-
1 ½ cups (135 g) old-fashioned rolled oats
- Avoid instant oats, which turn mushy.
- Bob’s Red Mill or Quaker both give great texture.
-
1 teaspoon baking soda
-
½ teaspoon fine sea salt
-
1 teaspoon ground cinnamon
- Optional but highly recommended for that cozy zucchini bread vibe.
Wet ingredients
- ½ cup (115 g) unsalted butter, softened to room temperature
- Use plant-based butter sticks for a dairy-free version.

- This combo of butter and oil keeps cookies soft and chewy.
- ¾ cup (150 g) packed light brown sugar
- ¼ cup (50 g) granulated sugar

- Use a flax egg for vegan: 1 tablespoon ground flax + 3 tablespoons water, rested 5 minutes.
- 2 teaspoons pure vanilla extract
Zucchini
- 1 cup (about 130 g) finely shredded zucchini, lightly squeezed
- One small to medium zucchini usually gives enough.
- Pat dry with paper towels to remove excess moisture but keep it slightly damp so the cookies stay soft.
Mix-ins

1 cup (170 g) semisweet chocolate chips
- Use mini chips if you want chocolate in every bite.

-
½ cup (60 g) chopped walnuts or pecans, optional

Quick Tips & substitutions
- Squeeze zucchini gently; keep some moisture so the cookies stay soft, but avoid dripping wet shreds.
- Use room temperature butter and egg so the dough mixes evenly.
- Chill the dough for 20 minutes if your kitchen feels warm; this helps cookies hold shape.

How to Make Zucchini Oatmeal Chocolate Chip Cookie Recipe
Step 1: Prep the zucchini and pans
Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats. Wash the zucchini, trim the ends, and grate it on the fine side of a box grater.
Place the shredded zucchini in a clean kitchen towel or a few layers of paper towel. Gently squeeze out excess liquid until it feels damp but not soggy. Measure 1 cup of the squeezed zucchini and set it aside.
Step 2: Mix the dry ingredients
In a medium bowl, add flour, oats, baking soda, salt, and cinnamon. Whisk everything until the mixture looks uniform and no streaks of baking soda remain. Set the bowl aside.
Step 3: Cream the butter, oil, and sugars
In a large mixing bowl, add softened butter, oil, brown sugar, and granulated sugar. Beat with a hand mixer or stand mixer on medium speed for about 2 to 3 minutes until the mixture looks light and fluffy. Scrape down the sides of the bowl with a spatula so everything mixes evenly.
Add the egg and vanilla extract to the bowl. Beat again on medium speed until the mixture looks smooth and slightly thick. Scrape the bowl once more.
Step 4: Add zucchini and dry ingredients
Add the shredded zucchini to the wet mixture. Stir with a spatula until the zucchini spreads evenly through the batter. The mixture might look slightly curdled, but it smooths out once you add the dry ingredients.
Pour the dry ingredient mixture into the bowl with the wet ingredients. Mix on low speed or stir with a spatula until you see no dry flour pockets. Stop mixing as soon as the dough comes together so you keep the cookies tender.
Step 5: Fold in chocolate chips and nuts
Add the chocolate chips and nuts, if using. Fold them in gently with a spatula until they spread evenly through the dough. The dough should feel thick and scoopable.
If the dough looks very loose or shiny, place the bowl in the fridge for 15 to 20 minutes. This short chill helps the oats hydrate and keeps the cookies from spreading too much.
Step 6: Scoop and shape the cookies
Use a cookie scoop or tablespoon to portion about 1 ½ tablespoons of dough per cookie. Place the dough mounds on the prepared baking sheets, leaving about 2 inches between each cookie. Gently flatten the tops with your fingers so they bake evenly.
Press a few extra chocolate chips on top of each dough ball if you want that bakery-style look. Work quickly so the dough stays cool and holds shape.
Step 7: Bake
Place one baking sheet in the center of the oven. Bake for 10 to 12 minutes, until the edges look set and lightly golden and the centers still look slightly soft. The cookies continue to firm up as they cool.
If you bake two trays at once, rotate them halfway through baking so they cook evenly. Adjust the time by a minute or two if your oven runs hot or cool.
Step 8: Cool and enjoy
Remove the baking sheet from the oven and let the cookies cool on the sheet for 5 minutes. Transfer the cookies to a cooling rack to cool completely. The texture settles as they cool, and the oats and zucchini give you a soft, chewy center.
Taste one while still slightly warm, just to check your quality control. The chocolate should feel melty and the cookie should bend, not snap.
Recipe Variations
- Gluten free: Use a 1:1 gluten free baking flour and certified gluten free oats.
- Vegan: Use plant-based butter, a flax egg, and dairy free chocolate chips.
- Low sugar: Cut the brown sugar to ½ cup and the granulated sugar to 2 tablespoons, then use dark chocolate chips.
- Low carb-ish: Swap half the flour with fine almond flour and use a low sugar chocolate chip; expect a softer cookie.
- Nutty: Add ½ cup chopped walnuts, pecans, or almonds for crunch.
- Spiced: Add ¼ teaspoon nutmeg or cardamom with the cinnamon for a cozy twist.
- Raisin twist: Swap half the chocolate chips with raisins for a more classic oatmeal cookie feel.
- Seed boost: Stir in 2 tablespoons chia seeds or flax seeds for extra texture and fiber.

- Add the egg and vanilla extract to the butter mixture and beat again on medium speed until smooth and slightly thick. Scrape the bowl once more.
- Stir in the shredded zucchini until evenly distributed. The mixture may look slightly curdled, which is normal.
- Add the dry ingredients to the wet ingredients and mix on low speed or with a spatula just until no dry flour remains and the dough comes together.
- Fold in the chocolate chips and nuts, if using, until evenly dispersed. If the dough looks very loose, chill it for 15 to 20 minutes to firm slightly.
- Scoop about 1 1/2 tablespoons of dough per cookie onto the prepared baking sheets, spacing about 2 inches apart. Gently flatten the tops with your fingers. Press a few extra chocolate chips on top if desired.
