“Absolutely amazing, rich and delicious; better after chilling. My husband, who isn’t a chocolate lover, had a few pieces. If you love chocolate, you won’t be disappointed.” –Carol
Why this is the cake I always make for friends
- Fast and simple. Like my Healthy Zucchini Cake, this recipe uses minimal ingredients and one bowl. It’s perfect for busy cooks and easy enough to hand off to a helper. You don’t need to peel or squeeze the zucchini, which keeps prep painless.
- Hard to mess up. This batter is forgiving — just be sure to use almond flour, not regular all-purpose flour. The almond flour gives the cake a wonderfully moist, tender crumb.
- Tastes indulgent but is nourishing. It delivers classic chocolate cake flavor while using wholesome ingredients — less refined sugar and gluten free.
Let’s make it!
Whisk almond flour, cocoa powder, baking soda, and salt together until evenly combined.
Stir in the maple syrup, eggs, and vanilla until the batter is smooth.
Fold in the grated zucchini and chocolate chips. The batter will be thick — that’s normal.
Spoon the batter into a prepared 8×8-inch baking dish lined with parchment or sprayed with cooking spray.
Bake at 350°F (175°C) for about 25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Allow the cake to cool completely on a wire rack, then frost if desired and enjoy.
Behind the scenes of recipe testing
I’ve tested this cake many times and refined it to a reliably delicious result. A few notes from testing:
- Chill it. This cake tastes noticeably better after resting in the fridge. Chilling enhances the chocolate flavor and firms the texture; many testers preferred it the next day.
- Use almond flour only. Almond flour provides essential fat and moisture, so other flours like all-purpose or coconut won’t produce the same result.
- Short on zucchini? If you only have about 1 cup grated zucchini, add 2 tablespoons melted butter to the batter to maintain moistness.
- Eggs are needed. Eggs provide structure and lift for this recipe.
- Don’t overdo the cocoa. I found that around 1/3 cup cocoa powder gives balanced chocolate flavor; adding more made the cake too intense.
Quick reminder: this cake includes zucchini and almond flour, so it’s more nourishing than a typical treat, but it’s still dessert — enjoy it for what it is.

Description
Crazy easy, moist, and decadent chocolate zucchini cake that’s unexpectedly wholesome. Made with almond flour and sweetened with maple syrup, this one-bowl cake is versatile and crowd-pleasing. Gluten free, dairy free, and grain free.
Ingredients
- 2 cups almond flour*
- ⅓ cup cocoa powder
- 1 tsp baking soda
- ¼ tsp fine sea salt
- ½ cup pure maple syrup
- 2 large eggs
- 1 ½ tsp vanilla extract
- 1 ½ cups grated zucchini, no need to peel or squeeze out water
- ½ cup chocolate chips
- 1 batch healthy chocolate cream cheese frosting (optional) or serve with vanilla ice cream
Instructions
- Preheat oven to 350°F (175°C). Spray an 8×8-inch baking dish with cooking spray or line it with parchment paper.
- Whisk almond flour, cocoa powder, baking soda, and salt in a medium bowl.
- Stir in the maple syrup, eggs, and vanilla. Fold in the grated zucchini and chocolate chips.
- Spoon the batter into the prepared baking dish and smooth the top. Bake for about 25 minutes, until a toothpick comes out with a few moist crumbs.
- Meanwhile, prepare frosting if using, or plan to serve with ice cream. Cool the cake on a wire rack. Once completely cool, frost and store in the fridge — it’s best chilled and often even better the next day.
Notes
Adapted from a healthy carrot cake recipe.
*Use almond flour only for the intended texture and moisture — other flours (all-purpose, coconut, etc.) will not produce the same result.
Frosted cake can sit at room temperature for up to 2 hours, but should be refrigerated afterward. This cake also freezes well.
