- ½ cup granulated sugar: Sweetens the bars without overpowering the vegetable presence.
- ½ cup packed light brown sugar: Adds a subtle caramel note and extra moisture.
- 1 large egg: Binds everything together while contributing to the soft texture.
- 1 teaspoon vanilla extract: Lends a smooth, comforting aroma that elevates every bite.

How to Make Chocolate Chip Zucchini Cookie Bars
Step 1: Prep Your Oven and Pan
Start by preheating your oven to 350°F (175°C) and lining a 9×13 inch baking pan with parchment paper. This ensures an easy release and neatly cut bars once baked.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking soda, cinnamon, and salt. This blend creates the aromatic, fluffy base for your Chocolate Chip Zucchini Cookie Bars.
Step 3: Cream Butter and Sugars
Using a large bowl, beat the softened butter with granulated and brown sugars until the mixture is light and fluffy—a crucial step that contributes to the bars’ tender crumb.
Step 4: Add Egg and Vanilla
Beat in the egg and vanilla extract until fully combined, creating a smooth and luscious wet mixture ready to be joined with the dry ingredients.
Step 5: Fold in Zucchini
Gently fold the shredded zucchini into the wet mixture. This step adds moisture naturally, keeping your cookie bars soft and flavorful.
Step 6: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Overmixing here can toughen the bars, so mix gently!
Step 7: Stir in Chocolate Chips
Finally, fold in the chocolate chips to ensure even distribution, giving each bite delightful bursts of chocolate.
Step 8: Bake the Bars
Spread the batter evenly in your prepared pan and bake for 20-25 minutes. You’ll know they’re ready when the edges turn a beautiful golden brown and a toothpick inserted in the center comes out clean.
Step 9: Cool and Cut
Allow your Chocolate Chip Zucchini Cookie Bars to cool completely in the pan before slicing into bars. This cooling period helps them set perfectly.
How to Serve Chocolate Chip Zucchini Cookie Bars

Garnishes
For an extra special touch, sprinkle a few chocolate chips or a light dusting of powdered sugar on top. A smear of cream cheese frosting can also elevate these bars from everyday snack to dessert-worthy delight.
Side Dishes
These bars pair wonderfully with a scoop of vanilla ice cream or a cup of freshly brewed coffee or tea, making them perfect for breakfast, afternoon snack, or dessert.
Creative Ways to Present
Try serving your Chocolate Chip Zucchini Cookie Bars on a rustic wooden board with fresh berries and mint leaves for a charming presentation. Cutting them into bite-sized squares can also turn them into party-friendly finger foods.
Make Ahead and Storage
Storing Leftovers
Keep any leftover bars stored in an airtight container at room temperature for up to three days. They stay moist and fresh, perfect for an easy grab-and-go snack.
Freezing
You can freeze Chocolate Chip Zucchini Cookie Bars by wrapping them tightly in plastic wrap and placing them in a freezer bag. They’ll keep well for up to two months and thaw quickly for a sweet treat anytime.
Reheating
Warm up your bars gently in the microwave for 15-20 seconds or in a low oven (about 300°F) for a few minutes to restore that freshly baked feel and melty chocolate goodness.
FAQs
Can I use another type of flour?
Yes, you can substitute whole wheat flour for a nuttier flavor and added fiber, but the bars might be a bit denser. Using all-purpose flour keeps them light and tender.
Do I need to peel the zucchini?
Not at all! The skin is thin and soft, especially when shredded, so leaving it on adds extra nutrients and color to your Chocolate Chip Zucchini Cookie Bars.
How do I prevent the bars from being too wet?
Make sure to squeeze out excess moisture from the shredded zucchini using a clean kitchen towel or paper towels. This step prevents soggy bars and ensures the perfect texture.
Can I add nuts or other mix-ins?
Absolutely! Chopped walnuts, pecans, or even dried cranberries make excellent additions that add crunch and variety to these cookie bars.
Are these bars healthy?
While they do include a good amount of sugar and butter like most treats, the zucchini adds moisture and some nutrients, making these a slightly better-for-you cookie bar option.
Final Thoughts
Once you try these Chocolate Chip Zucchini Cookie Bars, they’ll quickly become your go-to for a moist, flavorful treat that cleverly sneaks in some veggies. They’re perfect for sharing, gifting, or keeping all to yourself when you want a sweet but thoughtful snack. You really can’t go wrong with this recipe—give it a shot and watch everyone fall in love!
