Ingredients List
For these extra-fudgy vegan zucchini brownies, you’ll need:

- 1 cup all-purpose flour (substitute: whole wheat pastry flour or a 1:1 gluten-free blend for gluten-free option)
- 1/2 cup unsweetened cocoa powder (Dutch process for richer chocolate flavor)
- 3/4 cup coconut sugar (sub: organic cane sugar, date sugar, or a zero-calorie natural sweetener for lower glycemic impact)
- 1/2 tsp baking soda
- 1/4 tsp salt
- 1/2 cup melted coconut oil (sub: avocado oil or a mild olive oil for heart-healthy fats)
- 1/4 cup unsweetened plant milk (almond, oat, or soy all work well)
- 1/2 cup vegan chocolate chips (choose fair-trade for sustainability)
- 1 tsp pure vanilla extract
Optional add-ins:

Step-by-Step Instructions
1. Preheat & Prep
Preheat your oven to 350°F (175°C). Line an 8×8-inch square pan with parchment paper, leaving a slight overhang for easy brownie removal. Lightly grease for added non-stick security.
Tip: Parchment paper helps maintain moisture and guarantees clean slices.
2. Prepare the Zucchini
Wash, trim, and grate your zucchini using the finer side of a box grater. Gently blot with a clean towel don’t squeeze dry! Retaining some moisture is crucial for that gooey crumb.
Personal touch: If you love extra fudge, leave the zucchini wetter. For lighter brownies, blot a bit more.
3. Mix Dry Ingredients
In a large bowl, whisk together flour, cocoa powder, coconut sugar, baking soda, and salt until uniformly combined. This creates an even cocoa distribution vital for a balanced taste.
Advanced trick: Sift the cocoa for superbly silky texture.
4. Combine Wet Ingredients
In a separate bowl, gently combine grated zucchini, melted coconut oil, plant milk, and vanilla extract. Stir until just blended; avoid overmixing to prevent toughness.
5. Bring It All Together
Pour the wet mixture into the dry, stirring until just incorporated. Fold in vegan chocolate chips (and nuts, if using). The batter will be thick and lusciously dark perfect for fudgy brownies.
Velocity tip: Overmixing is the #1 culprit of cakey brownies. Stop as soon as you no longer see dry flour.
6. Bake to Perfection
Spread the batter evenly in your prepared pan. Top with extra chocolate chips for a show-stopping finish. Bake 28–32 minutes. Insert a toothpick: it should come out with a few moist crumbs, not clean.
Personalized tip: For extra-fudgy centers, aim for the lower end of baking time.
7. Cool, Slice & Serve
Let brownies cool at least 15 minutes in the pan (they continue to set as they cool). Use the parchment to lift out, then slice into squares with a damp, sharp knife for perfect edges.
