Step‑by‑Step Instructions for Chocolate Chip Zucchini Cookie Bars
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, allowing some overhang for easy removal later. This step is essential for even baking and helps prevent sticking, so don’t skip it!
Step 2: Whisk Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and salt until well combined. This ensures that your dry ingredients are evenly distributed, resulting in a consistent texture for your Chocolate Chip Zucchini Cookie Bars.
Step 3: Cream Butter and Sugars
In a large mixing bowl, beat together the softened unsalted butter, granulated sugar, and brown sugar using a hand mixer on medium speed for 2-3 minutes until the mixture is light and fluffy. The air incorporated during this process will give your cookie bars their scrumptious texture.
Step 4: Add Egg and Vanilla
Add the egg and high-quality vanilla extract to the creamed butter and sugar mixture. Beat until everything is well combined and smooth. The addition of these ingredients will enhance the flavor and contribute to the velvety texture of your Chocolate Chip Zucchini Cookie Bars.
Step 5: Incorporate Shredded Zucchini
Take your grated zucchini, and gently squeeze out any excess moisture. Fold the zucchini into the wet mixture until evenly distributed, which helps keep the cookie bars moist and flavorful while subtly incorporating vegetables into this delicious treat.
Step 6: Combine Dry and Wet Ingredients
Gradually mix the dry ingredient mixture into the wet ingredients using a spatula or wooden spoon until just combined. Be careful not to overmix, as this can lead to denser bars. You want a cohesive batter that’s still slightly lumpy with pockets of goodness!
Step 7: Fold in Chocolate Chips
Gently fold in your chocolate chips, ensuring they’re evenly distributed throughout the batter. The rich chocolatey bites will provide delightful bursts of sweetness in every bite of your Chocolate Chip Zucchini Cookie Bars.
Step 8: Spread Batter in Pan
Carefully spread the cookie batter into the prepared baking pan, smoothing the top with a spatula. Make sure the batter is evenly distributed so that it bakes evenly, with all edges and corners getting that golden-brown finish.
Step 9: Bake to Perfection
Place the pan in the preheated oven and bake for 20-25 minutes. Keep an eye on them towards the end; they're done when the edges are golden brown, and a toothpick inserted in the center comes out clean. This will ensure a perfect texture for your cookie bars.
Step 10: Cool Before Slicing
Once baked, remove the pan from the oven and let it cool completely in the pan. This cooling period is crucial as it helps the bars set perfectly, making them easier to cut into squares. Patience is key for delicious results with your Chocolate Chip Zucchini Cookie Bars!

How to Store and Freeze Chocolate Chip Zucchini Cookie Bars
Room Temperature: Store these delicious bars in an airtight container at room temperature for up to 3 days to maintain their moisture and chewiness.

Freezer: For longer storage, freeze slices individually, wrapped tightly in plastic wrap or a freezer-safe bag. They can last up to 2 months in the freezer without losing flavor.
Reheating: When you're ready to enjoy your frozen Chocolate Chip Zucchini Cookie Bars, simply reheat them in the microwave for 10-15 seconds to bring back that fresh-baked texture!

Expert Tips for Chocolate Chip Zucchini Cookie Bars
• Moisture Management: Squeeze excess moisture from zucchini before adding it to the batter; this prevents sogginess for perfectly chewy Chocolate Chip Zucchini Cookie Bars.

• Ingredient Quality: Opt for high-quality vanilla extract and chocolate chips; the flavors will shine through, elevating your cookie bars’ taste!
