1. Ultimate Fudgy Zucchini Brownies | Healthy Hidden Veggie Dessert

Prep Time: 15 minutes | Cook Time: 30 minutes | Servings: 12 brownies

Ingredients:

• 2 cups all-purpose flour
• 1 cup unsweetened cocoa powder
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 1 cup granulated sugar
• 1/2 cup brown sugar
• 1/2 cup vegetable oil
• 2 large eggs
• 2 teaspoons vanilla extract
• 2 cups grated zucchini (unpeeled, squeezed dry)
• 1 cup chocolate chips

Step-by-Step Instructions:

Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal. Lightly grease the parchment paper.

Step 2: Mix Dry Ingredients
In a large bowl, whisk together the flour, cocoa powder, baking soda, and salt until well combined and no lumps remain. This ensures even distribution of leavening agents.

Step 3: Combine Wet Ingredients
In a separate bowl, beat together the granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract until smooth and slightly fluffy, about 2 minutes.

Step 4: Prepare the Zucchini
Grate the zucchini using the large holes of a box grater. Place the grated zucchini in a clean kitchen towel and squeeze out excess moisture. This is crucial for achieving the right texture.

Step 5: Combine Wet and Dry
Add the wet ingredients to the dry ingredients and mix until just combined. Do not overmix. Fold in the grated zucchini and chocolate chips.

Step 6: Bake
Spread the batter evenly into the prepared pan. Bake for 28-32 minutes, or until a toothpick inserted in the center comes out with moist crumbs (not wet batter).

Step 7: Cool and Serve
Allow the brownies to cool completely in the pan before lifting them out using the parchment paper. Cut into 12 squares and serve.

Pro Tip: For extra fudgy brownies, slightly underbake them by 1-2 minutes. They’ll continue to set as they cool.

2. Vegan Zucchini Brownies (Eggless) | Easy One Bowl Recipe

Prep Time: 15 minutes | Cook Time: 30 minutes | Servings: 12 brownies

Ingredients:

• 1 1/2 cups all-purpose flour

• 1/2 teaspoon salt
• 1 cup coconut sugar
• 1/2 cup melted coconut oil
• 1 cup unsweetened applesauce

Step 5: Transfer to Pan
