Step‑by‑Step Instructions for Simple Zucchini Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease a jelly roll pan measuring 10.5 x 15.5 inches with cooking spray or a thin layer of oil to ensure your Simple Zucchini Bars won’t stick. This will create a smooth, easy release once they’re baked and ready to cool.
Step 2: Mix Wet Ingredients
In a large mixing bowl, combine 1/2 cup of vegetable oil, 1/2 cup of granulated sugar, 1/2 cup of brown sugar, 3 eggs, and 2 teaspoons of vanilla extract. Using a whisk, blend these ingredients together until the mixture is smooth and well combined. This step ensures the sugars dissolve and creates a rich base for your bars.
Step 3: Combine Dry Ingredients
Next, add 2 cups of all-purpose flour, 1 cup of old-fashioned oats, 2 teaspoons of baking powder, 1 teaspoon of salt, and 1 tablespoon of ground cinnamon into the wet mixture. Gently fold the dry ingredients into the wet with a spatula or wooden spoon until just combined. Be careful not to overmix—the key to tender Simple Zucchini Bars is to keep your batter airy.
Step 4: Fold in Zucchini
Now it’s time to bring in the star ingredient! Fold in 1 medium grated zucchini, which should be well-drained and free of excess moisture. Stir gently until the zucchini is evenly distributed throughout the batter, ensuring every bite of your zucchini bars will have a delightful touch of this summer squash.
Step 5: Bake the Bars
Pour the batter into your prepared pan, spreading it out evenly with a spatula. Place the pan in the oven and bake for 18-22 minutes. The bars are done when they turn a beautiful golden brown and a toothpick inserted in the center comes out clean or with a few moist crumbs—a perfect sign of their moist, cake-like texture.
Step 6: Cool Completely
Once baked, remove the pan from the oven and let the Simple Zucchini Bars cool in the pan on a wire rack for about 30 minutes. This cooling step is essential to allow the bars to set properly and makes the frosting process easier once they are ready to be frosted.
Step 7: Prepare the Frosting
While the bars cool, prepare the luscious cream cheese frosting. In a medium bowl, beat 8 ounces of softened cream cheese with 1/4 cup of unsalted butter using an electric mixer until fluffy and smooth. Gradually add in 3 cups of powdered sugar and 1 teaspoon of vanilla extract, mixing well until the frosting is light and creamy.
Step 8: Frost and Serve
Once the bars have cooled completely, spread the cream cheese frosting evenly over the top using a spatula. After frosting, cut the Simple Zucchini Bars into squares or rectangles for serving. They’re now ready to be enjoyed as a delightful dessert or a sweet snack!

How to Store and Freeze Simple Zucchini Bars
Fridge: Store your Simple Zucchini Bars in an airtight container in the refrigerator for up to 5 days. This helps maintain the creamy frosting and keeps them fresh.
Freezer: For longer storage, freeze the bars in individual portions wrapped tightly in plastic wrap and placed in a freezer-safe bag. They can last up to 3 months and still taste delicious when defrosted!
Reheating: To enjoy, simply thaw the frozen bars in the refrigerator overnight. You can also warm them briefly in the microwave for a few seconds to soften the frosting.
Make Ahead Options
These Simple Zucchini Bars are a fantastic option for meal prep, saving you time on busy days! You can prepare the batter up to 24 hours in advance—simply mix the wet and dry ingredients together, fold in the grated zucchini, and store it in the refrigerator until you’re ready to bake. Just remember to give it a quick stir before pouring it into the pan, as some moisture may settle. The bars can also be frosted ahead and stored in an airtight container for up to 3 days in the fridge, ensuring they stay fresh and delicious. When you’re ready to serve, just slice them up for a guilt-free treat that maintains its flavor and moistness beautifully!
