Irresistible Chocolate Chip Zucchini Cookies

If you ask me, sneaking vegetables into cookies is one of the smartest baking tricks out there.

These chocolate chip zucchini cookies are a simple way to use up extra garden zucchini while making something the whole family will actually eat. The shredded zucchini keeps the cookies soft and chewy without adding any vegetable taste.

They’re loaded with chocolate chips and crunchy walnuts, with a hint of cinnamon that makes them taste like fall. The zucchini basically disappears into the dough, so even picky eaters won’t know it’s there.

It’s an easy recipe that turns summer produce into a treat everyone can feel good about.

What Kind of Zucchini Should I Use?

Any fresh zucchini from your garden or the grocery store will work great for these cookies. Medium-sized zucchini are ideal because they’re easier to shred and tend to have fewer seeds than the really large ones, which can sometimes be a bit watery. The key is to make sure you squeeze out as much liquid as possible after shredding – just wrap the shredded zucchini in a clean kitchen towel or paper towels and give it a good squeeze over the sink. If your zucchini seems particularly wet or you picked a larger one, you might need to squeeze it twice to get rid of all that extra moisture, which will help keep your cookies from spreading too much or turning out soggy.

Options for Substitutions

These cookies are pretty forgiving when it comes to swaps, so here are some options:

• Salted butter: You can use unsalted butter instead – just add an extra pinch of salt to the dry ingredients. Coconut oil also works if you’re looking for a dairy-free option, though the texture will be slightly different.
• Zucchini: Yellow squash makes a great substitute and works exactly the same way. Just remember to squeeze out the excess moisture no matter which you use, or your cookies will spread too much.
• Brown sugar: If you only have granulated sugar, you can use it for the full amount, but your cookies will be a bit less chewy. For a closer match, add 1 tablespoon of molasses to the granulated sugar.
• All-purpose flour: White whole wheat flour can replace up to half the all-purpose flour for added nutrition. Going all whole wheat might make them a bit dense, so I’d stick with a partial swap.
• Semi-sweet chocolate chips: Dark chocolate chips, milk chocolate chips, or even butterscotch chips all work great here. Mix and match based on what you like or have on hand.
• Walnuts: Pecans, almonds, or even sunflower seeds make good substitutes. Or skip the nuts entirely if you prefer – the cookies will still turn out delicious.

Watch Out for These Mistakes While Baking

The biggest mistake when making zucchini cookies is skipping the step of squeezing out excess moisture from the shredded zucchini – if you don’t do this, your cookies will spread too much and turn out flat and cake-like instead of thick and chewy.

Another common error is not giving your cookies enough space on the baking sheet, so make sure to place them at least 2 inches apart since they’ll spread during baking.

To get the perfect texture, pull your cookies from the oven when the edges are just set but the centers still look slightly underdone – they’ll continue cooking on the hot pan and firm up as they cool.

For extra flavor, try toasting your walnuts in a dry skillet for a few minutes before adding them to the dough, which brings out their natural oils and adds a deeper, richer taste.

What to Serve With Chocolate Chip Zucchini Cookies?

These cookies are perfect with a cold glass of milk for dunking, or try them with a hot cup of coffee for an afternoon snack. I love packing them in lunchboxes alongside some fresh fruit like apple slices or grapes to balance out the sweetness. They also make a great dessert when served with a scoop of vanilla ice cream, especially if you warm them up for a few seconds in the microwave first. For a fun party idea, set them out on a platter with other baked goods like brownies or banana bread for a casual dessert spread.

Storage Instructions

Store: These cookies stay soft and chewy when kept in an airtight container at room temperature for up to 5 days. If you want them to last a bit longer, pop them in the fridge where they’ll keep for about a week.

Freeze: You can freeze baked cookies in a freezer-safe container or bag for up to 3 months. I also love freezing the cookie dough in balls on a baking sheet, then transferring them to a bag once frozen so I can bake fresh cookies whenever a craving hits.

Enjoy: Frozen cookies thaw quickly at room temperature in about 20 minutes, or you can warm them in the microwave for 10-15 seconds for that fresh-baked feel. If you froze the dough, just add a couple extra minutes to the baking time and bake straight from frozen.

• Calories: 3000-3200
• Protein: 30-34 g
• Fat: 150-165 g
• Carbohydrates: 400-420 g

Ingredients

• 3/4 cup unsalted butter, softened
• 1/2 cup granulated sugar
• 1 cup light brown sugar, packed
• 1 large egg, room temperature
• 2 1/2 teaspoons vanilla extract
• 1 1/4 cups finely shredded zucchini, squeezed dry
• 2 1/2 cups all-purpose flour
• 1 teaspoon baking soda
• 1 1/4 teaspoons kosher salt
• 1/2 teaspoon ground cinnamon
• 1 cup semi-sweet chocolate chips
• 1/2 cup roughly chopped walnuts

Step 1: Prepare mise en place and preheat oven

• 1 1/4 cups zucchini, finely shredded and squeezed dry
• Parchment paper

Preheat your oven to 375°F and line a baking sheet with parchment paper.

While the oven heats, prepare your ingredients: finely shred the zucchini and squeeze it dry in a clean kitchen towel or paper towels—this removes excess moisture that would otherwise make the cookies dense and cake-like.

Bring your egg and butter to room temperature if they aren’t already, as this helps create a smoother, more uniform dough.

Measure out all your dry ingredients and set them aside together.

Step 2: Cream butter and sugars for light, fluffy dough

• 3/4 cup unsalted butter, softened
• 1/2 cup granulated sugar
• 1 cup light brown sugar, packed

In a large bowl, beat the softened butter with both sugars for 3-5 minutes until the mixture is light and fluffy—this incorporates air and creates a tender cookie texture.

You’ll notice the mixture change from dense to pale and voluminous.

This step is crucial for the final cookie structure, so don’t rush it.

Step 3: Incorporate wet ingredients and zucchini

• butter and sugar mixture from Step 2
• 1 large egg, room temperature
• 2 1/2 teaspoons vanilla extract
• squeezed-dry zucchini from Step 1

Add the room temperature egg and vanilla extract to the creamed mixture and beat until fully combined.

Then add the squeezed-dry zucchini from Step 1, stirring gently just until no white streaks remain.

I like to fold the zucchini in rather than aggressively beat it so it distributes evenly without breaking down further and releasing excess moisture into the dough.

Step 4: Mix dry ingredients and fold into wet mixture

• wet ingredient mixture from Step 3
• 2 1/2 cups all-purpose flour
• 1 teaspoon baking soda
• 1 1/4 teaspoons kosher salt
• 1/2 teaspoon ground cinnamon
• 1 cup semi-sweet chocolate chips
• 1/2 cup roughly chopped walnuts

In a separate small bowl, whisk together the flour, baking soda, salt, and cinnamon.

Add this dry mixture to the wet ingredients from Step 3 and stir until just combined—do not overmix, as this develops gluten and makes cookies tough.

Fold in the chocolate chips and walnuts until evenly distributed throughout the dough.

Step 5: Shape and bake cookies

• dough from Step 4
• prepared baking sheet from Step 1

Drop rounded tablespoon-sized portions of dough onto the preheated baking sheet, spacing them about 4 inches apart since they will spread during baking.

Bake for 9-11 minutes, until the edges are set but the centers still look slightly underdone—they’ll continue to cook as they cool.

I pull mine out when the edges just turn golden but the tops still look a touch moist, which keeps them tender inside.

Step 6: Cool and finish

Allow the cookies to cool on the baking sheet for 5 minutes—this lets them set just enough to handle without falling apart.

Then transfer them to a wire cooling rack to cool completely.

This final resting on the pan prevents them from spreading too much and ensures even baking throughout.
