Ingredients

For the Cake

• 1 ½ cups (210 g) all-purpose gluten-free flour blend (I love using Better Batter, but make sure your blend has xanthan gum or add it separately).

• ¾ teaspoon xanthan gum (omit if your blend already contains it).

• ½ cup (40 g) unsweetened cocoa powder (Dutch-processed preferred for richer flavor; if using natural, add 1/8 teaspoon baking soda).

• ½ teaspoon kosher salt.

• 1 ½ teaspoons baking powder.

• ¾ cup (150 g) granulated sugar.

• 3 tablespoons (41 g) packed light brown sugar.

• 2 ¾ cups (170 g) shredded zucchini (from about 2 large or 3 medium zucchini), drained of excess liquid (see notes!).

• 6 tablespoons (84 g) neutral oil (vegetable, canola, grapeseed, or even peanut oil).

• 1 teaspoon pure vanilla extract.

• 3 large eggs (150 g total, weighed out of shell), at room temperature, lightly beaten.

• 9 tablespoons (4.5 fluid ounces) buttermilk, at room temperature.

• 4 ounces chocolate chunks or chips (optional, but highly recommended!).

  
  

For the Fudge Frosting

• ⅔ cup (5 ⅓ fluid ounces) evaporated milk.

• 1 cup (200 g) granulated sugar.

• 4 ounces bittersweet chocolate, melted.

• 4 tablespoons (56 g) unsalted butter, melted.

  
  

Step-by-Step Instructions

1. Prep Your Zucchini: Grate your zucchini using the large holes of a box grater. Place it in a fine-mesh sieve over a bowl and let it sit for at least 15-20 minutes to drain. Gently squeeze out any remaining liquid with your hands or by pressing down with a spoon. This step is crucial to avoid a soggy cake!

2. Preheat & Prep Pan: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or line it with parchment paper if you prefer easy removal.

3. Whisk Dry Ingredients: In a large bowl, whisk together the gluten-free flour blend, xanthan gum (if using), cocoa powder, salt, and baking powder. Make sure there are no lumps, especially from the cocoa.

4. Combine Wet Ingredients: In a separate medium bowl, whisk together the granulated sugar, brown sugar, drained shredded zucchini, neutral oil, vanilla extract, room temperature eggs, and buttermilk until well combined. It might look a little rustic, and that’s perfectly fine!

5. Combine Wet and Dry: Pour the wet ingredients into the bowl with the dry ingredients. Stir gently until just combined. Be careful not to overmix. If you’re adding chocolate chunks or chips, fold them in now.

6. Bake the Cake: Pour the batter into your prepared baking pan and spread it evenly. Bake for 30-40 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean (a few moist crumbs are okay, but no wet batter).

7. Cool the Cake: Let the cake cool in the pan on a wire rack for at least 20-30 minutes before attempting to frost it. Cooling completely makes it much easier to handle.

8. Make the Frosting: While the cake cools, prepare the fudge frosting. In a medium saucepan, combine the evaporated milk and granulated sugar. Bring to a boil over medium heat, stirring constantly. Boil for 2 minutes, continuing to stir.

9. Finish the Frosting: Remove the saucepan from the heat. Stir in the melted bittersweet chocolate and melted butter until the frosting is smooth and glossy.

10. Frost the Cake: Once the cake has cooled sufficiently (warm is okay, but not piping hot), pour the frosting over the top and spread it evenly to the edges. Let the frosting set slightly before slicing and serving.

Tips & Variations for Your Gluten-Free Chocolate Zucchini Cake

• 
  

  Zucchini Prep is Key: Don’t skip draining the zucchini! This is the *most* important step for a perfectly textured cake. A little effort here saves you from a dense, gummy mess later.

• Room Temperature Ingredients: Using room temperature eggs and buttermilk helps them incorporate more smoothly into the batter, leading to a more tender cake. If you forget, just pop your eggs in a bowl of warm water for 5-10 minutes and microwave your buttermilk for 15-20 seconds.

• Cocoa Powder Matters: Dutch-processed cocoa powder gives a smoother, less acidic chocolate flavor. If you only have natural cocoa powder, the addition of a tiny bit of baking soda helps balance the acidity.

• Frosting Fun: Feeling fancy? Add a teaspoon of espresso powder to the frosting while it’s still warm to enhance the chocolate flavor even more. You could also swirl in some peanut butter or cream cheese frosting for a different twist.

• Storage: This cake is best stored in an airtight container at room temperature for up to 3 days. The moisture from the zucchini helps keep it fresh! You can also refrigerate it for a slightly firmer texture, but let it come to room temp before serving.

• Freezing: Yes, you can freeze this! Wrap cooled, unfrosted cake layers tightly in plastic wrap, then foil. Thaw overnight in the refrigerator. Frost once thawed. Baked and unfrosted cake layers freeze beautifully for up to 3 months.

  
  

Serving Suggestions

This Gluten-Free Chocolate Zucchini Cake is fantastic on its own, especially with that luscious fudge frosting. However, if you want to elevate it slightly, consider serving it with a cold glass of milk (dairy or non-dairy!). For a more decadent dessert experience, a scoop of your favorite vanilla bean ice cream alongside a warm slice is pure bliss. It also makes a wonderful addition to any brunch spread, a potluck, or a simple afternoon tea. It’s truly that versatile.

Frequently Asked Questions (FAQ)

Can I freeze this Gluten-Free Chocolate Zucchini Cake?

Absolutely! Baked and cooled cake layers can be wrapped tightly and frozen for up to 3 months. Thaw overnight in the fridge before frosting. The unfrosted cake also freezes well.

How can I make this cake ahead of time?

You can bake the cake layers a day in advance and store them at room temperature, well-wrapped, until you’re ready to frost and serve. The frosting can also be made a day ahead and gently reheated over low heat before spreading onto a cooled cake.

Can I use a different type of gluten-free flour?

While I recommend a good all-purpose blend like Better Batter, you can experiment with other 1:1 gluten-free flour blends. Results may vary slightly depending on the specific blend’s composition. Always check if your blend contains xanthan gum.

My batter seems a little thick, is that normal?

Yes, a slightly thick batter is normal for this recipe, especially after adding the drained zucchini. You can stir in an extra tablespoon or two of buttermilk if it seems exceptionally stiff, but don’t overwork it.

How do I ensure my zucchini is well-drained?

The best way is to shred the zucchini, place it in a fine-mesh sieve over a bowl, and then gently press down on it with a spoon or spatula to extract as much liquid as possible. You can even wrap it in a clean kitchen towel and give it a good squeeze.
