Ingredients
For these decadent Zucchini Brownies, gather the following ingredients:
For the Brownies
- ½ cup (112 g) vegetable oil
- 1 ½ cups (300 g) granulated sugar
- 1 tablespoon vanilla extract
- 2 cups (256 g) all-purpose flour
- ½ cup (64 g) unsweetened cocoa powder
- 1 ½ teaspoon baking soda
- 1 teaspoon kosher salt
- 3 cups finely shredded zucchini (DO NOT DRAIN)
- 1 ¼ cups semi-sweet chocolate chunks
How to Make Zucchini Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F. Prepare a 9×13 pan by greasing it with butter or using baking spray. Line the bottom with parchment paper, allowing it to extend up the sides for easy removal later.
Step 2: Mix Wet Ingredients
In a large bowl, combine:
1. Vegetable oil
2. Granulated sugar
3. Vanilla extract
Mix until fully incorporated.
Step 3: Combine Dry Ingredients
Add the following dry ingredients to the wet mixture:
1. All-purpose flour
2. Unsweetened cocoa powder
3. Baking soda
4. Kosher salt
Stir until just combined; note that the batter will be quite dry at this stage.
Step 4: Fold in Shredded Zucchini
Gently fold in the finely shredded zucchini by hand until evenly distributed throughout the batter. Allow this mixture to rest for about 5 minutes.
Step 5: Add Chocolate Chunks
After resting, stir in:
1. Semi-sweet chocolate chunks
The batter should appear more wet after mixing. If it’s still dry, allow it to rest for another 5 minutes before stirring again.
Step 6: Bake Your Brownies
Spread the brownie mixture evenly into your prepared pan. Bake in the preheated oven for about 25–35 minutes. Check doneness by inserting a toothpick; it should come out with crumbs but not wet batter.
