Chocolate Zucchini Cookies

I really wanted to find a zucchini cookie that was not too ‘cakey’ and that actually had a significant amount of zucchini in it.  I wanted it to be full of deep, dark, rich chocolate, but I could not find it anywhere! And after quite a bit of testing (it all involved chocolate so I am definitely not complaining), I finally found a recipe we all loved!Double Chocolate Zucchini Cookies!

Chocolate Zucchini Cookies Recipe

Don’t even mention the zucchini in this recipe; no one will even notice, but they will notice how good these cookies are!

Ingredients (full recipe below)

  • Semi-sweet chocolate chips–You could also use bittersweet chips if you prefer.
  • Zucchini–Finely grate the zucchini and drain the excess moisture from it.
  • All-purpose flour
  • Cocoa
  • Baking soda
  • Salt
  • Butter
  • Brown sugar
  • Granulated sugar
  • Egg
  • Vanilla
  • Milk chocolate chips

Baking with Zucchini

When making these cookies, I used a medium-sized zucchini. A medium-sized zucchini is about a foot long and has a larger girth than a golf ball. Grate the zucchini as fine as your grater will allow, skin and all! To squeeze out the extra liquid, hold the zucchini in your hands and press out the extra moisture. You could also press the grated zucchini well with a clean towel to prevent these cookies from getting too soggy. This will give you about a cup of grated zucchini. 

As mentioned, I usually leave the skin ON, as I prefer for people to see the zucchini and know what they are in for.  If you want to be more ninja-like in your baking, simply peel the zucchini before grating it.

Chocolate Zucchini Cookie Dough

Once you have your zucchini grated and drained, set it aside as you prepare the cookie dough. Begin by melting the semisweet chocolate chips in a microwave-safe bowl. Start with 30 seconds; if the chocolate isn’t melted in that time, continue to melt it in 10-second increments until it is completely melted. Set it aside.

Next, whisk together the flour, cocoa, baking soda, and salt in a medium bowl. Set that bowl aside as well and get out your stand mixer or a large bowl if using a hand mixer. Mix together the butter and both sugars for about a minute, or until fluffy. Then, mixing on low, add the egg and vanilla and combine fully.

Mix in the melted chocolate completely, followed by the flour mixture until all the ingredients are incorporated. Finally, fold in the milk chocolate chips and drained zucchini by hand.

Baking the Cookies

Using an ice cream scoop or tablespoon, add scoops of dough to the parchment-lined baking sheets. Leave about 2 inches in between each cookie. No flattening is needed. But, you may want to add a few extra chocolate chips on the tops of the cookies before baking (as you can see I did in the pictures). Cook them for about 10 minutes; they will be slightly underdone.

Let them cool on the baking sheets before transferring them to the cooling racks. These are some of the best cookies I have ever had, zucchini or not.  The depth of flavor is going to be heaven to any chocolate lover. And the fact that there is so much zucchini in there makes you feel good about what you are eating.

Can I Use Frozen Zucchini?

Yes, you can! First, bring the frozen zucchini to room temperature. Since frozen zucchini collects extra moisture, you will definitely have to drain it before adding it to the recipe.

How to Store Chocolate Zucchini Cookies

Store the baked cookies in an airtight container at room temperature for a few days. If any of these cookies make it to day 2 or 3, be sure to pop them in the microwave for 10 seconds before nibbling. (Love that you can see the milk chocolate and dark chocolate right next to each other in this picture!  I was mid-bite, but had to share.)  There is something about the warm, oozing chocolate bits that make your eyes roll up in your head.

To freeze the cookies, let them cool completely before storing them in airtight, freezer-safe bags. Be sure to date and label the containers. They will last up to three months.

  • 1 medium (1 cup) zucchini, grated and drained
  • 2/3 cup semi-sweet chocolate chips, or bittersweet
  • 2 cups all-purpose flour
  • 1/4 cup (29.5g) cocoa
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt fine table salt
  • 1/2 cup (1 stick or 113g) butter room temperature
  • 1/2 cup (100g) brown sugar
  • 1/4 cup (50g) granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla
  • 1 cup milk chocolate chips
  1. Preheat oven to 325°F. Prepare cookie sheets with parchment paper.

  2. Using a grater, finely grate a medium sized zucchini. This should yield about 2 cups of zucchini. Place zucchini in a clean dish towel and squeeze vigorously, removing most of the liquid. You should now have about 1 cup of drained shredded zucchini. Set aside.
  3. In a microwave-safe bowl, melt the semi-sweet chocolate chips for 30 seconds. If chips are not melted, return to microwave in 10-second increments until mostly melted. Stir frequently. When melted, set aside.

  4. In a medium bowl, add flour, cocoa, baking soda, and salt. Sift together with a whisk. Set aside.
  5. In a stand mixer or bowl with a hand mixer, add in butter and sugars. Mix for about a minute, or until mixture is fully combined and starts to fluff.
  6. With a stand mixer (or hand mixer on low), add in egg and vanilla. Combine fully.

  7. Pour in melted chocolate and mix completely.
  8. Add flour mixture to chocolate mixture and mix on low speed until just incorporated.
  9. Remove bowl from stand mixer (or remove hand mixer) and fold in zucchini and milk chocolate chips by hand.

  10. With an ice cream scoop (or large spoon) drop balls of dough onto a cookie sheet, about 8 per sheet. Leave 2-inches between each ball of dough. (I did not flatten cookies at any point)

  11. Bake for 10-12 minutes.
  12. Remove from oven and let sit on the pan for 5-10 minutes before transferring cookies to a cooling rack.

  • Jolena @TheRubyKitchen says:

    I use two dark chocolate and cocoa in my zucchini bread. Although, I guess it is more like cake! I have never tried zucchini in cookies though. These look delicious!!

    • Amanda says:

      Your bread sounds amazing!

  • Erin says:

    Great recipe, though the directions were a little confusing. You stated to melt the semisweet chips, but you never said when to incorporate them. Nor did you state when to incorporate the flour mixture (although that’s pretty easy to figure out. ) But these are delicious and my kids are now devouring zucchini without even know it lol.

    • Amanda says:

      My apologies! Should be fixed now. Glad you are enjoying them!

    • Susan Berton says:

      How many does this recipe make?

  • Maria Howard says:

    I confess I must be soooo dumb…. I can not see where you added the flour mix. Maybe when you said fully combined? well, by logic I guess it is.
    Another thing….. you said use an ice cream scoop…. you left the cookies like that? or you flatten them before?
    I did not flatten them but they where almost ready and still little mounts :)) anyway, I flatten them before fully done….
    I guess I am not good to read recipes…. you know, when we have to use the logic… I guess I expect to have all steps :))
    The cookies are sooooo delicious… I guess after all I am not so dumb hehe… they are really good….

    • Amanda says:

      Not your error, it was mine!~ My apologies. Should be all fixed now!

  • Angelyn @ Everyday Desserts says:

    my neighbors keep dropping off zucchini at my house … I’ve think I’ve just found a way to use it all up! yum!

  • Jennifer Deibel says:

    These look awesome! Think we are going to make them this week! Do you think it would work with some combination of whole wheat four? I know it is much denser, but I’m curious if you think it could work?

    • Amanda says:

      It is worth trying! If the whole wheat flour is denser, maybe you could try adding more baking soda or powder? I admit, I am woefully inept at working with healthier grains!

  • Tanya says:

    I need to sweet talk my neighbor into giving me some of their zucchini, I NEED these beautiful cookies!

  • Liz says:

    Is there a healthier/wheatless flour that you could use? They look wonderful!

    • Amanda says:

      Not sure Liz… but it is worth experimenting with!

  • Lauren says:

    Whoa, 3 types of chocolate?! That’s my type of cookie! Yum.

  • Beth says:

    when is the melted chocolate added? and is the flour mixture added in after the butter and sugars are beaten? are there additional semisweet chips – to get that look of the two flavored chips side by side?

    • Beth says:

      aha! just found out the recipe has been corrected! thanks!

    • Amanda says:

      I talked about that in the post Beth… I added some to the top for vanity purposes. Sorry about the initial errors!

  • Laura @ Laura's Culinary Adventures says:

    Thanks for doing all the testing for your benefit 🙂

  • Shannon @ Bake.Frost.Repeat says:

    Beautiful!! They look absolutely perfect. A guy at work brings in tons of zucchini from his garden and I’ve been making bread and muffins so much I’m sure everyone is sick of seeing me walk into the office with a bag of said bread and muffins. I can’t wait to make these. I’m sure minds will be blown! 🙂

  • Phi @ The Sweetphi Blog says:

    I’m on a huuuuge zucchini kick, and have a feeling I’m going to be making these cookies asap! They look absolutely fantastic!

  • Dena says:

    Made these last night………… they are divine! This recipe is a keeper for sure.

    • Amanda says:


  • Linda says:

    Just wondering, are these cookies soft or crunchy?

    • Amanda says:

      soft 🙂

  • Shalini says:

    When you say cocoa do you mean Dutch unprocessed cocoa?

    • Amanda says:

      Nope. Just regular cocoa.

  • beverley piercey says:

    Made these today..followed recipe exactly as you stated..found them hard to keep together, maybe I strained the zucchini too much…there is no other liquid that goes into this recipe? totally disappointed..

  • Annie’s little blessings says:

    These were so delicious! My little ones really like them. They were surprised to know that there is zucchini in their now favorite chocolate cookies. They were excited tot rlly white teachers at school that they could have a cookie for snack because “it’s healthy it has veggies in it.” Thank you for another great recipe. I’m trying the chocolate chip zucchini cookies and chocolate zucchini muffins next.

  • LINDA WILSON says:

    Just printed out these zucchini recipes. I am going to try them tomorrow.
    Some of the recipes call for a cup of veg oil. Have you ever tried it with 1/2 and 1/2 veg oil and applesauce??

    • Amanda Rettke says:

      haven’t used that recently but it is usually a good substitute.
