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)
- 1 small carrot (shredded)
- 3/4 cup rolled oats
- 1 cup chopped walnuts
For the Cream Cheese Frosting:
- 1/2 cup salted butter (room temperature)
- 8 ounces cream cheese (room temperature)
Cooking Instructions
Let’s get baking! The process is straightforward, and the results are incredibly rewarding.
Step 1: Prepare the Wet Ingredients and Preheat Your Oven
First things first, let’s get our oven ready and start building the base of our delicious zucchini bars. Preheat your oven to 350°F (175°C). This is a standard baking temperature that will ensure our bars cook through evenly without burning. Next, grab a large mixing bowl. Into this bowl, we’ll pour the 1 cup of vegetable oil and add the 2 cups of granulated sugar. Using an electric mixer (or a whisk and a good arm workout!), cream these two together until the mixture is well combined and looks light and fluffy. This step is crucial for creating a tender crumb in our finished bars. Now, it’s time to incorporate the eggs. Add the 3 large eggs, one at a time, beating well after each addition. Don’t rush this; letting each egg fully emulsify into the sugar and oil mixture contributes to the overall texture. Finally, stir in the 1 teaspoon of vanilla extract. This adds that quintessential warm, sweet aroma and flavor that complements the spices so beautifully.
Step 2: Combine the Dry Ingredients
In a separate medium-sized bowl, we’re going to whisk together all of our dry ingredients. This ensures that the leavening agents and spices are evenly distributed throughout the batter, preventing any pockets of baking soda or cinnamon. Measure out the 2 cups of all-purpose flour, the 1 teaspoon of ground cinnamon, the 1 teaspoon of salt, the 2 teaspoons of baking soda, and the 1/4 teaspoon of baking powder. Whisk them together thoroughly. It’s important to note the difference between baking soda and baking powder. Baking soda needs an acidic ingredient to activate (which we have in the buttermilk if you choose to use it, or even just the slight acidity of the zucchini itself), while baking powder contains its own acid. Using both gives us a fantastic lift and a delicate texture.
Step 3: Incorporate Zucchini, Carrot, Oats, and Nuts
Now comes the star ingredient: the zucchini! Gently shred your 2 cups of zucchini. A box grater is perfect for this. The key here is to *not* squeeze out the moisture. The moisture from the zucchini is what keeps these bars incredibly moist and tender. If you squeeze it, you’ll end up with drier bars. We also add 1 small shredded carrot. This adds a touch more moisture, a hint of natural sweetness, and a lovely subtle orange hue that’s visually appealing. Next, fold in the 3/4 cup of rolled oats. These contribute a lovely chewy texture and a slightly nutty flavor that complements the walnuts. Finally, stir in the 1 cup of chopped walnuts. I love the crunch and rich flavor walnuts bring, but feel free to substitute pecans or even omit them if you have nut allergies.
Step 4: Combine Wet and Dry and Bake
Now it’s time to bring everything together. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix at this stage. Overmixing can develop the gluten in the flour too much, resulting in tough bars. Once the flour is incorporated, gently fold in the zucchini, shredded carrot, rolled oats, and chopped walnuts by hand using a spatula. The batter will be quite thick. Grease and flour a 9×13 inch baking pan or line it with parchment paper. Pour the batter into the prepared pan and spread it evenly. Bake in your preheated oven for 30-35 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean. The aroma that fills your kitchen at this stage is simply divine!
Step 5: Prepare and Apply the Cream Cheese Frosting
While the bars are baking, let’s whip up the irresistible cream cheese frosting. In a medium bowl, beat together the 1/2 cup of softened salted butter and the 8 ounces of softened cream cheese. Ensure both the butter and cream cheese are at room temperature; this is crucial for achieving a smooth, lump-free frosting. Use an electric mixer to beat them until they are light, fluffy, and perfectly combined. You want a consistency that is spreadable but not too runny. Once the zucchini bars are completely cooled (this is important – frosting warm bars will result in a melty mess!), spread the cream cheese frosting evenly over the top. You can use an offset spatula for a smooth finish or a regular spatula for a more rustic look. For an extra touch, you can sprinkle a few more chopped walnuts or a dash of cinnamon on top of the frosting before it sets. Once frosted, cut the bars into your desired size – I usually go for about 24 bars. These are best stored in an airtight container in the refrigerator due to the cream cheese frosting. Enjoy every moist, flavorful bite!
