Ingredients

For the Fudgy Cake Base:

Zucchini: 1 ½ cups, very finely grated and packed (about 1 medium zucchini). Note: Do NOT squeeze out the moisture.
Flour: 1 ½ cups, all-purpose flour (for a GF option, use a reliable 1-to-1 baking blend).
Cocoa Powder: ½ cup, high-quality, unsweetened Dutch-process cocoa powder, sifted.
Leaveners: 1 tsp baking soda, ½ tsp baking powder.
Spice: ½ tsp sea salt.
Sweetener: 1 cup granulated coconut sugar or light brown sugar.
Fats & Moisture: ½ cup neutral oil (like melted coconut or avocado oil), ½ cup unsweetened applesauce, ¼ cup plant-based milk (oat or almond work well).
Flavor: 2 tsp pure vanilla extract.
Texture: ¾ cup vegan semi-sweet chocolate chunks or chips.

For the Optional (But Highly Recommended) Ganache Frosting:

½ cup semi-sweet vegan chocolate chunks.
¼ cup full-fat canned coconut milk (shaken).

Step-by-Step Instructions

Get Ready: Preheat your oven to 180°C (350°F). Lightly grease a 9-inch round cake pan (or an 8×8 square pan) and line the bottom with parchment paper for easy removal.
The Hidden Star: Wash the zucchini and grate it on the finest setting of your grater. Remember, you want the moisture, so do not squeeze it out. Just pack it into the measuring cup.
Whisk the Dry: In a large bowl, sift together the flour, cocoa powder, baking soda, baking powder, and salt. Add the sugar and whisk until fully combined and lump-free.
Mix the Wet: In a separate medium bowl, whisk together the oil, applesauce, plant milk, and vanilla extract until smooth. Fold in the finely grated zucchini and mix again.
Combine: Pour the wet ingredients into the dry ingredients. Using a large spatula, gently fold the mixture together just until no dry streaks of flour remain. Do not overmix, or the cake can become tough. Fold in the chocolate chunks.
Bake: Pour the batter into your prepared pan and smooth the top. Bake for 30-35 minutes. You’ll know it’s done when the edges start to pull away slightly from the pan, and a toothpick inserted into the center comes out with just a few moist crumbs (no wet batter).
Cool: Remove the cake from the oven and let it cool completely in the pan on a wire rack before attempting to frost it or lift it out.
Make the Ganache (If Frosting): Place the ½ cup chocolate chunks in a small heat-proof bowl. In a small saucepan, bring the canned coconut milk just to a simmer (do not boil). Pour the hot milk over the chocolate chunks and let sit for 3 minutes. Gently whisk from the center outwards until a smooth, shiny glaze forms. Let the ganache sit at room temperature for 15-20 minutes to thicken slightly, then spread over the completely cool cake.

Baker’s Tips & Storage

Finely Grate is Key: The most important tip is to grate the zucchini as finely as possible. This ensures it completely “dissolves” into the batter texture, leaving no green specks behind.
The Applesauce Secret: The applesauce is crucial here; it works alongside the zucchini to add that rich fudgy texture while allowing us to use less oil.
Storage: This cake is famous for its keeping power! Store it covered at room temperature for 2 days, or in the fridge for up to 5 days. It freezes beautifully, wrapped tightly, for up to 2 months.
