Ingredients:
- 1 cup vegetable oil
- 2 cups granulated sugar
- 3 large eggs
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon ground cinnamon
- 1 teaspoon salt
- 2 teaspoons baking soda
- 1/4 teaspoon baking powder
- 2 cups shredded zucchini (don’t squeeze)

- 3/4 cup rolled oats
- 1 cup chopped walnuts
- 1/2 cup salted butter (room temperature)
- 8 ounces cream cheese (room temperature)
Instructions:

Prepare the Pan and Preheat the Oven
Before we dive into mixing our delicious batter, it’s essential to get your baking setup ready. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). This consistent temperature is key to ensuring your bars bake evenly. Next, prepare a 9×13 inch baking pan. I like to lightly grease the pan and then line it with parchment paper, leaving some overhang on the sides. This makes it incredibly easy to lift the entire baked slab of bars out of the pan once they’re cooled, which is a lifesaver when it comes to cutting them neatly. You can also dust the greased pan with a little flour after greasing if you don’t have parchment paper.
-
Mix the Wet Ingredients and Sugar
In a large mixing bowl, combine the 1 cup of vegetable oil and 2 cups of granulated sugar. Whisk them together until well combined. This forms the base of our moist and tender bars. Next, add the 3 large eggs, one at a time, whisking well after each addition to incorporate them fully into the oil and sugar mixture. Finally, stir in the 1 teaspoon of vanilla extract. You’ll notice the mixture becomes lighter and slightly frothy, which is exactly what we want. This step ensures that all our wet ingredients are emulsified, contributing to a smooth and consistent batter.
-
Combine the Dry Ingredients and Add to Wet Mixture
In a separate medium-sized bowl, whisk together the 2 cups of all-purpose flour, 1 teaspoon of ground cinnamon, 1 teaspoon of salt, 2 teaspoons of baking soda, and 1/4 teaspoon of baking powder. Whisking the dry ingredients together ensures that the leavening agents (baking soda and baking powder) and the salt are evenly distributed throughout the flour, which will prevent any pockets of bitterness or uneven rising in the final bars. Now, gradually add this dry mixture to the wet ingredients in the large bowl. Mix on low speed or by hand until just combined. Be careful not to overmix at this stage; overmixing can develop the gluten in the flour, leading to tougher bars. A few streaks of flour remaining are perfectly fine.

Fold in the Zucchini, Carrot, Oats, and Nuts
This is where the magic really starts to happen! Gently fold in the 2 cups of shredded zucchini. Remember, we’re not squeezing out any moisture from the zucchini – that liquid is precious and contributes to the incredible moistness of these bars. Next, fold in the 1 small shredded carrot. The carrot adds a delightful subtle sweetness and color. Finally, stir in the 3/4 cup of rolled oats and the 1 cup of chopped walnuts. The oats add a lovely chewiness and a nutty flavor, while the walnuts provide a satisfying crunch. Again, mix until everything is just incorporated. The batter will be thick and dense, packed with all those wonderful add-ins.
-
Bake the Bars and Prepare the Frosting
Pour the batter evenly into your prepared 9×13 inch baking pan. Spread it out gently to create an even layer. Place the pan in your preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. While the bars are baking, it’s time to prepare the luscious cream cheese frosting. In a medium bowl, beat together the 1/2 cup of softened salted butter and 8 ounces of softened cream cheese until smooth and creamy. If your butter and cream cheese aren’t at room temperature, they will be lumpy. You can speed this up by cubing the butter and cream cheese and leaving them on the counter for about 30-60 minutes. Once the bars are baked, remove them from the oven and let them cool completely in the pan on a wire rack. This is crucial! If you try to frost warm bars, the frosting will melt and slide right off. Patience is key here!
-
Frost and Cut the Bars
Once the zucchini bars are completely cool, it’s time for the grand finale! Spread the prepared cream cheese frosting evenly over the top of the cooled bars. You can use an offset spatula for a smooth, professional finish. Once frosted, use the parchment paper overhang to carefully lift the entire slab of bars out of the pan and onto a cutting board. Now you can cut them into your desired bar size. I usually cut mine into about 2-inch squares. For the neatest cuts, especially with the frosting, I recommend using a sharp knife and wiping it clean between each cut. You’ll be amazed at how moist and flavorful these bars are, with the perfect balance of sweet, spice, and tang from the frosting. Enjoy every single bite!

Conclusion:
I truly believe these are The Best Zucchini Bars you’ll ever make! They strike the perfect balance of moist, tender crumb with just the right amount of sweetness, all while cleverly incorporating fresh zucchini for added moisture and a hint of earthy goodness. The warm spices in the batter create an irresistible aroma as they bake, and the simple glaze adds a delightful finishing touch. These bars are incredibly versatile, making them a fantastic treat for any occasion. Enjoy them fresh from the oven for a warm, gooey delight, or allow them to cool for a firmer, more cake-like texture.
For serving suggestions, these zucchini bars are wonderful on their own as an afternoon snack, alongside a cup of coffee or tea. They also make a delightful addition to a brunch spread or a potluck dessert table. Feel free to get creative with variations! You could add a handful of chopped nuts like walnuts or pecans for a delightful crunch, or even stir in some chocolate chips for a decadent twist. Don’t be afraid to experiment with different spices like nutmeg or ginger to tailor the flavor profile to your preference. I highly encourage you to give this recipe a try – you won’t be disappointed!
Frequently Asked Questions:
Can I freeze these zucchini bars?
Yes, absolutely! Once cooled completely, you can wrap them tightly in plastic wrap and then aluminum foil, or store them in an airtight container. They should stay fresh in the freezer for up to 2-3 months. Thaw them overnight in the refrigerator before enjoying.
How can I make these bars gluten-free?
To make these gluten-free, I recommend using a good quality all-purpose gluten-free flour blend that contains xanthan gum. You may need to adjust the liquid content slightly, so keep an eye on the batter’s consistency. Baking time might also vary, so test for doneness with a toothpick.
