From the roundup: 24 Zucchini Cookies Recipes Easy Enough for Any Home Baker
These zucchini triple spice molten center cookies are the ones I make when I need a serious chocolate cookie and I have a zucchini sitting on the counter that nobody is going to eat otherwise. The dough comes together in about 15 minutes, and the hardest part is actually pulling them out of the oven when they still look slightly underdone. I’ve overbaked this batch before, and the difference between fudgy and dry is honestly just one or two minutes.
The “triple spice” in the name refers to the layered chocolate: Dutch-process cocoa in the dough, plus a full 4 ounces of hand-chopped dark chocolate folded in. Chopping a bar yourself gives you a mix of big shards that melt into pools and tiny flecks that scatter through every bite. Chocolate chips don’t do that. The zucchini disappears completely into the dough and just keeps things soft in the middle without making the cookie taste like a vegetable.
You get 22 cookies from one batch, which is enough to feed my crew and still have some left for school lunches the next day. Flaky sea salt goes on right out of the oven while the cookies are still hot. That part matters more than it sounds.
Why you will love this
- Shredded zucchini keeps the centers fudgy without adding any detectable vegetable flavor.
- Hand-chopped dark chocolate creates uneven pockets of chocolate that melt differently than uniform chips.
- The batch makes 22 cookies, enough for a crowd or a couple of days of snacking.
- Total time is 26 minutes, including prep, so these are realistic on a weeknight.
- Flaky sea salt on top does real work here, cutting through the richness so you actually want a second cookie.
Tips for success
- Squeeze the zucchini until the towel stops dripping. If you skip this step or rush it, the extra moisture will make the dough slack and the cookies won’t hold their shape on the pan.
- Flatten each dough mound slightly before baking. This dough does not spread much on its own, so a gentle press with your palm helps them bake evenly instead of staying in a tall mound.
- Pull the pan at 10 to 12 minutes when the edges are set but the tops still look a little underdone. They firm up as they cool. If they look fully baked in the oven, they will be dry by the time they cool.
- Sprinkle the flaky salt the moment the pan comes out. If you wait even a few minutes, the surface cools and the salt won’t stick properly.
Common questions
- Can I use a food processor to shred the zucchini? Yes, but the shreds will be finer. Still squeeze out the moisture thoroughly before measuring.
- My cookies came out cakey. Did I overbake? Possibly, or the zucchini wasn’t squeezed dry enough. Both will push the texture toward cakey instead of fudgy.
- Can I use chocolate chips instead of a chopped bar? You can, but you’ll lose the big melty pools that make these cookies worth the extra knife work.
- Do these taste like zucchini? No. Once baked, the zucchini is completely undetectable to my pickiest kids.
Substitutions
Semisweet chocolate works in place of dark if your family prefers a sweeter cookie. For a dairy-free version, use vegan butter and a dairy-free dark chocolate bar. A 1-to-1 gluten-free flour blend can replace the all-purpose flour without changing the method. If you only have natural unsweetened cocoa, it works fine, though the cookies will be slightly lighter in color and a bit less intense in chocolate flavor than they are with Dutch-process.
Make-ahead and storage
To freeze unbaked dough, scoop into balls, freeze on a parchment-lined sheet until solid, then transfer to a zip bag. Bake straight from frozen at 350 degrees F for 13 to 15 minutes, and add the flaky salt immediately when they come out. Store baked cookies in an airtight container at room temperature for up to 4 days. Layer them with parchment so the salt flakes stay intact instead of rubbing off onto the cookies below.
Baked cookies freeze well for up to 2 months. Reheat a single frozen cookie in the microwave for 20 to 25 seconds and it comes back close to fresh-baked, soft center and all.

Ingredients
Equipment
Method
- Preheat the oven to 350 degrees F. Line two baking sheets with parchment paper and set them aside.
- Grate the zucchini on the large holes of a box grater. Bundle the shreds in a clean kitchen towel and squeeze hard over the sink until the towel stops dripping. Measure 1 cup of the pressed zucchini and set it aside.
- Chop the dark chocolate bar on a cutting board using a sharp knife. Aim for a mix of small shards and larger rough chunks, about 1/4 to 1/2 inch. The uneven sizes are what give you both big melty pools and little flecks throughout the baked cookie. Set aside.
- In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and fine salt until the cocoa is fully incorporated with no streaks. Set aside.
- In a large bowl, beat the softened butter, brown sugar, and granulated sugar together on medium speed for 2 minutes until the mixture is light and fluffy. Add the egg and vanilla and beat for another 30 seconds.
- Pour the flour and cocoa mixture into the butter mixture and stir with a spatula until just combined. The dough will look dark and fudgy. Fold in the squeezed zucchini and the chopped chocolate chunks, stirring until everything is evenly distributed.
- Scoop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. Give each mound a gentle press to flatten slightly since the dough will not spread dramatically on its own.
- Bake for 10 to 12 minutes. The edges should look set and the tops should appear dry and just barely crackled. The centers will look slightly underdone, but that is correct. They firm up to a fudgy texture as they cool. Do not wait until they look fully baked in the oven or they will dry out.
- Pull the pans from the oven and immediately sprinkle a pinch of flaky sea salt over each cookie while they are still hot. This is when the salt sticks properly. Let the cookies rest on the pan for 5 minutes, then transfer to a wire rack to finish cooling.
