Step‑by‑Step Instructions for Chocolate Chip Zucchini Cookie Bars
Step 1: Preheat and Prepare Pan
Start by preheating your oven to 350°F (175°C). While the oven warms, take an 8×8-inch baking dish and grease it lightly with cooking spray or line it with parchment paper. This will help the chocolate chip zucchini cookie bars release easily once baked, ensuring you have a perfect presentation when it's time to slice.
Step 2: Mix Wet Ingredients
In a large mixing bowl, combine ½ cup of melted unsalted butter and 1 cup of brown sugar. Whisk them together until the mixture is smooth and glossy, which should take about 1-2 minutes. Next, add in 1 large egg and 1 teaspoon of vanilla extract, continuing to whisk until fully integrated. This forms the rich base for your cookie bars.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together 1 and ½ cups of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, 1 teaspoon of ground cinnamon, and a pinch of salt. Make sure there are no lumps in the flour mixture, as this will help create a light texture in your chocolate chip zucchini cookie bars.
Step 4: Combine Mixtures
Gradually add the dry mixture to your wet ingredients, stirring gently with a spatula or wooden spoon until just combined. Be careful not to overmix; a few flour streaks are okay. This ensures your cookie bars remain soft and chewy, perfect for indulging those sweet cravings.
Step 5: Fold in Zucchini and Chocolate Chips
Gently fold in 1 cup of grated zucchini and 1 cup of semi-sweet chocolate chips into the batter. Use a spatula to add these ingredients slowly, making sure they are evenly distributed without overworking the dough. The zucchini adds moisture, which is key to achieving deliciously moist cookie bars.
Step 6: Bake the Bars
Spread the batter evenly into the prepared baking dish, smoothing the top with a spatula for an even bake. Place it in the preheated oven and bake for 25–30 minutes. You’ll know the cookie bars are done when a toothpick inserted in the center comes out clean, with just a few moist crumbs clinging to it.
Step 7: Cooling
Once baked, remove your chocolate chip zucchini cookie bars from the oven and let them cool in the pan on a wire rack for about 10 minutes. Then carefully transfer the bars to the rack and allow them to cool completely. This step is crucial as it helps the bars set, facilitating easier slicing and enhancing the overall texture of the dessert.

Make Ahead Options
These Chocolate Chip Zucchini Cookie Bars are a fantastic choice for meal prep, saving you time during busy weeknights!

Store the grated zucchini in an airtight container in the refrigerator to maintain its freshness. When you're ready to bake, simply combine the wet and dry ingredients, fold in the zucchini and chocolate chips, and bake according to the recipe instructions. This method ensures your bars are just as delicious and moist when prepared ahead, allowing you to whip up a delightful treat with minimal effort!

Expert Tips for Chocolate Chip Zucchini Cookie Bars
- Choose Fresh Zucchini: Select firm, fresh zucchini to ensure optimal moisture and flavor in your cookie bars. Overripe zucchini can make the bars soggy.
- Adjust Sweetness: If you're using sweeter alternatives like honey or maple syrup, remember to lessen the added sugar slightly for balanced sweetness in your Chocolate Chip Zucchini Cookie Bars.
- Don’t Skip the Cooling: Allow the bars to cool completely before cutting. This prevents crumbling and ensures you achieve beautiful, clean slices every time.
- Check Your Flour: Spoon and level your flour rather than scooping directly from the bag; this prevents overpacking, yielding a lighter texture in your bars.
- Experiment with Spices: Enhance flavor by trying different spices like nutmeg or cloves. Just a pinch can elevate your Chocolate Chip Zucchini Cookie Bars to a new level.

Freezer: For longer storage, individually wrap the bars in plastic wrap or foil and place them in a freezer-safe bag. They’ll keep well for up to 2 months.
Reheating: When you're ready to enjoy a frozen bar, simply thaw it overnight in the fridge, then heat in the microwave for about 15-20 seconds for that fresh-out-of-the-oven experience.
