Ingredients you’ll need

Ingredients for zucchini chocolate chip cookies assembled and measured.
  • Salted butter: I almost always bake with salted butter these days as it has more flavor, but unsalted is fine too.
  • Zucchini: You’ll need one cup of shredded zucchini, shredded with a box grater or food processor.
  • Chocolate chips: Dark or semi-sweet are my favorite for this recipe.
  • Chopped walnuts: You can also use pecans, or leave the nuts out completely.

How to make zucchini chocolate chip cookies

Step 1: Shred zucchini and squeeze out extra liquid. Too much liquid from the zucchini will make the cookies misshapen and soggy.

Annalise’s expert tips

  • Starting with butter at the right temperature is key! Butter should be soft enough that a pressed finger will leave an indent, but not soft enough that your finger can press all the way through. If it’s shiny or melty at all, the butter is too warm and your cookies may spread.
  • Be sure to measure flour correctly. All of my recipes are tested using the spoon and level method (more info through that link). For even more accuracy, use a kitchen scale to weigh ingredients.
  • If cookies come out slightly misshapen, use a spatula to press them back into a circle right after they come out of the oven. See more of my tips for how to bake pretty cookies.
  • Garnish with flaky sea salt for a sweet and salty combo, and extra flair.
  • How to store and freeze cookies: I love these cookies best the day they are baked. Store cookie dough in the fridge for a week or more and bake as you like. Or freeze cookie dough to bake anytime in the next few months.

baking tip:The importance of creaming butter and sugar when making cookies

When you beat butter and sugar together in a cookie recipe, you’re not just combining ingredients. You’re aerating the dough, creating tiny pockets of trapped air that puff up once the cookies hit the oven. When not done properly, your cookies will end up dense and flat, and no one wants that! Here are a few things to remember to ensure you’re creaming the right way:

  1. Make sure your butter is at a cool room temperature, and not too warm.
  2. Use an electric mixer with the paddle attachment.
  3. Beat for 4-5 minutes. You’re looking for a pale, fluffy mixture.
  4. Scrape down the bowl 1-2 times for a consistent dough.
  5. Use cold eggs to bring the temperature of the butter back down after it’s been creamed with the sugar.

Zucchini Chocolate Chip Cookies

Servings: 30 cookies
Prep Time: 15 minutes
Cook Time: 12 minutes
Total Time: 22 minutes
These zucchini chocolate chip cookies with chopped walnuts and a hint of cinnamon are a great late summer twist on the classic!

Ingredients
 

  • 1 cup (130 grams) shredded zucchini , packed (see Notes)
  • ¾ cup (170 grams) salted butter , softened to room temperature
  • ½ cup (100 grams) granulated sugar
  • 1 cup (213 grams) packed light or dark brown sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 2 ½ cup (330 grams) all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • ⅛-¼ teaspoon ground cinnamon
  • 1 cup (170 grams) semi-sweet chocolate chips
  • ½ cup (56 grams) chopped walnuts or pecans , optional

Instructions
 

  • Preheat oven to 375°F. Line a sheet pan with parchment paper.
  • Squeeze the shredded zucchini to remove excess liquid. I prefer to put it inside a paper towel or a clean tea towel, then wrap it and squeeze hard with my hands.
    1 cup (130 grams) shredded zucchini
  • In the bowl of an electric mixer, beat the butter, sugar, and brown sugar until light and creamy, 3-5 minutes. Stop to scrape down then bowl once or twice.
    ¾ cup (170 grams) salted butter, ½ cup (100 grams) granulated sugar, 1 cup (213 grams) packed light or dark brown sugar
  • Add the egg, vanilla, and squeezed zucchini, beating after each and scraping down the bowl at least once.
    1 large egg, 2 teaspoons vanilla extract
  • Add the flour, baking soda, salt and cinnamon and mix until almost combined. Add the chocolate chips and walnuts and mix briefly until incorporated.
    2 ½ cup (330 grams) all-purpose flour, 1 teaspoon baking soda, 1 teaspoon salt, ⅛-¼ teaspoon ground cinnamon, 1 cup (170 grams) semi-sweet chocolate chips, ½ cup (56 grams) chopped walnuts or pecans
  • Portion equally (I use a #40 1½ Tbsp scoop) and roll into rounds. Space evenly about 4 inches apart on prepared sheet pan.
  • Bake for 9-11 minutes until edges are golden and top is set but not at all browned.
  • Let cool on the sheet pan for 5 minutes, then transfer to a wire rack to cool completely. Repeat with remaining dough, letting the sheet pan cool in between batches.

Notes

  • Using zucchini in this recipe: 1 cup packed shredded zucchini is about 1 small, or 1/2 a medium zucchini. You must remove the excess liquid from the zucchini, otherwise the cookie dough will be too wet and the cookies won’t hold their shape during baking. 
  • You choose the amount of cinnamon: I provide a range so you can choose how spiced you want your cookies to be!
  • How to measure flour accurately: All recipes are tested with the spoon and level method of measuring flour. Gently scoop it into a measuring cup until it overflows, and then scrape a straight-edged knife across the top to level it flat. Or for most accurate results, use a kitchen scale and weigh in grams.
  • Cookie dough can be stored in the fridge for at least a week, so bake cookies fresh when you want them! Or freeze the dough balls for up to 1 month.
