Overview of the Recipe

What This Cake Is

This isn’t your average chocolate cake. It’s a flourless, fudge-like, melt-in-your-mouth dessert made with grated zucchini, almond flour, and rich cocoa powder. The zucchini keeps it perfectly moist — without tasting “veggie-like” at all!

Why You’ll Love It

  • Naturally gluten-free and grain-free
  • Incredibly moist, dense, and fudgy
  • No refined flour or guilt!
  • Sneaks in veggies (perfect for picky eaters)
  • Tastes like pure chocolate heaven

What It Tastes Like

Imagine the deepest, richest chocolate brownie — with a soft, velvety crumb and a hint of nutty sweetness from almond flour. The zucchini disappears into the batter, leaving only that glorious moist texture you’ll crave after the first bite.

Ingredients

For the Cake:

  • 1 ½ cups (150 g) almond flour
  • ½ cup (50 g) high-quality unsweetened cocoa powder
  • 1 cup (200 g) coconut sugar or light brown sugar
  • 2 large eggs
  • 1 medium zucchini, finely grated (about 1 cup)
  • ¼ cup (60 ml) melted coconut oil or olive oil
  • 1 tsp pure vanilla extract
  • ½ tsp baking soda
  • ¼ tsp sea salt
  • Optional: ½ cup dark chocolate chips (for that gooey touch!)

Tools You’ll Need

  • Mixing bowls
  • Whisk & spatula
  • Box grater
  • 8×8-inch square or round baking pan
  • Parchment paper

Suggested Substitutions

  • Almond flour: Try oat flour for a nut-free version.
  • Coconut sugar: Maple syrup or honey works beautifully (just reduce oil slightly).
  • Eggs: Substitute 2 flax eggs for a vegan version.

How to Make Super Fudgy Chocolate Zucchini Cake

  1. Prep Your Pan
    Preheat your oven to 350°F (175°C). Line your baking pan with parchment paper and lightly grease it.
  2. Mix Dry Ingredients
    In a medium bowl, whisk together almond flour, cocoa powder, baking soda, and salt.
  3. Combine Wet Ingredients
    In a separate bowl, whisk eggs, sugar, melted oil, and vanilla until smooth.
  4. Add Zucchini
    Fold in grated zucchini — don’t squeeze it dry! The natural moisture is what gives this cake its dreamy texture.
  5. Bring It All Together
    Combine wet and dry ingredients, stirring until no dry spots remain. Fold in chocolate chips if using.
  6. Bake to Perfection
    Pour batter into the prepared pan and bake for 25–30 minutes or until the center is just set.
  7. Cool (if you can wait!)
    Let it cool in the pan for at least 20 minutes. The texture sets as it cools — and becomes fudgier by the minute.

What to Serve with Chocolate Zucchini Cake

  • A dollop of whipped coconut cream or vanilla Greek yogurt.
  • A drizzle of melted dark chocolate or espresso glaze.
  • Fresh raspberries for a tart contrast.

Or serve it warm with a scoop of my Homemade Vanilla Ice Cream — trust me, it’s dessert nirvana.

Tips for Making It Perfect

  • Don’t overbake! Slightly underbaked means extra fudge.
  • Use finely grated zucchini. It should melt into the batter.
  • Rest before slicing. This cake gets better as it sits.
  • Add-ins: Chopped walnuts, espresso powder, or even a swirl of nut butter.

Storage Instructions

  • Store at room temp for 2–3 days or refrigerate for up to 5.
  • For long-term storage, wrap slices individually and freeze up to 2 months.
  • Reheat in the microwave for 10–15 seconds for that gooey, fresh-from-the-oven feel.

General Information

Did you know zucchini adds moisture without changing flavor — and even adds fiber and vitamin C? My grandma used to slip it into muffins and brownies long before it was trendy. This recipe is my modern take on that wholesome trick, with a luxurious chocolate twist.
