Ingredients Needed

To make this chocolate zucchini cake from scratch, you’ll need the following:

For the Dry Mix:

• 4 cups all-purpose flour – spooned and leveled

• 1 ½ cups unsweetened cocoa powder – sifted for a smoother batter
• 4 tsp baking soda – essential for rise
• 2 tsp baking powder – helps lighten the crumb
• 2 tsp ground cinnamon – optional, but adds warmth
• 1 tsp salt – enhances the overall flavor

For the Wet Mix:

• 3 cups vegetable oil – neutral, keeps the cake moist

Add-Ins:

• 6 cups shredded zucchini – use fresh, medium zucchinis, unpeeled
• 1 ½ cups chopped walnuts – toasted for extra flavor (optional)

How to Make Chocolate Zucchini Cake

Step-by-Step Instructions

Step 1: Prep Your Oven and Pan
Preheat your oven to 350°F (175°C). Lightly grease and flour a 9×13-inch baking pan, or line it with parchment for easier removal.

Step 2: Mix the Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, cinnamon, and salt. This ensures everything is evenly distributed and lump-free.

Step 3: Add the Wet Ingredients
Pour in the vegetable oil and eggs. Stir just until combined—overmixing at this stage can lead to a dense cake.

Step 4: Fold in the Zucchini and Nuts
Gently fold in the shredded zucchini and chopped walnuts. You’ll notice the batter start to loosen slightly—that’s totally normal.

Step 5: Bake the Cake
Pour the batter into your prepared pan. Tap it gently on the counter to release air bubbles. Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean. The top should feel springy, and the edges may slightly pull away from the pan.

Step 6: Cool Before Frosting
Let the cake cool in the pan for 15–20 minutes, then transfer it to a wire rack to cool completely. Frost with your favorite chocolate frosting—or leave it plain and dust with powdered sugar for a simpler finish.

Serving and Storage Tips

Serving Suggestions:

• Slice into squares and top with a dollop of whipped cream or vanilla ice cream.
• Dust with powdered sugar for a rustic, fuss-free finish.
• Add a drizzle of ganache for extra decadence.
• Pair with coffee or red wine for a grown-up dessert moment.

Storage:

• At Room Temp: Store covered in an airtight container for up to 3 days.
• In the Fridge: Wrap well and refrigerate for up to a week.
• In the Freezer: Freeze unfrosted slices for up to 3 months. Thaw in the fridge or at room temp.

Helpful Notes

• Zucchini Prep: No need to peel your zucchini—the skin melts right in. Use a box grater and press lightly to avoid sogginess.
• Nut-Free Option: Skip the walnuts or replace them with chocolate chips for a double-chocolate version.
• Frosting Ideas: Cream cheese frosting adds tang, while classic buttercream keeps it sweet.
• Gluten-Free? Try using a 1:1 gluten-free flour blend—results may vary slightly but still delicious.
• Make it a Layer Cake: Divide the batter into two 9-inch round pans. Bake for 35–40 minutes.

Frequently Asked Questions (FAQ)

Can I use a different type of oil?

Yes, you can substitute vegetable oil with canola oil or light olive oil. Avoid oils with strong flavors like coconut or sesame.

How do I make this gluten-free?

Swap in a 1:1 gluten-free baking flour with xanthan gum. Make sure to sift it to avoid clumping.

Can I freeze this cake?

Absolutely! Let it cool completely, wrap individual slices in plastic wrap, and freeze in an airtight container for up to 3 months.

What if I don’t like nuts?

No problem—just leave them out or swap for dark chocolate chunks to keep the texture interesting.

How finely should I shred the zucchini?

Use the fine side of a box grater. Coarse shreds may add too much texture. You want it to blend smoothly into the batter.
