Description These zucchini oatmeal chocolate chip cookies are extra soft with chewy centers and crisp edges. You can’t taste the vegetable hiding inside! Chill the dough for at least 2 hours before baking.
1 cup (140g) shredded & blotted zucchini (see step 1)
2 cups (160g) old-fashioned whole rolled oats*
1 cup (125g) all-purpose flour (spoon & leveled)
1/2 teaspoon baking soda
1/2 teaspoon salt
1 teaspoon ground cinnamon
1/2 cup (1 stick; 115g) 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
1 cup (180g) semi-sweet chocolate chips
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 (140g) 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.)
Whisk the oats, flour, baking soda, salt, and cinnamon together in a medium bowl. Set aside.
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 2 minutes. 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.
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.
Preheat oven to 350°F (177°C). Line baking sheets with parchment paper or silicone baking mats. Set aside.
Scoop or roll cookie dough, a heaping 1.5 Tablespoons of dough per cookie, 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.
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.
Cookies stay fresh covered at room temperature for up to 5 days or in the refrigerator for 1 week.
Make Ahead & Freezing Instructions: Baked cookies freeze well up to three months. Unbaked cookie dough balls freeze well – up to three months. Bake frozen cookie dough balls for an extra minute, no need to thaw. Here’s how to freeze cookie dough.
Zucchini: I do not peel the zucchini before shredding, but you certainly can if you’d like.
Oats: For these oatmeal cookies, I use and recommend old-fashioned whole oats, not quick or instant oats. Whole oats provide the ultimate hearty, chewy, and thick texture.
Maple Syrup: The maple syrup adds flavor, but it also helps the cookies spread out and crisps up the edges. You can use honey instead or even molasses for a strong flavor– or you can leave it out completely. (Though I highly recommend its addition!)
