Zucchini's Sweet Secret: A Vegan Chocolate Swirl Cake Adventure!

Zucchini's Sweet Secret: A Vegan Chocolate Swirl Cake Adventure!

21 April 2025

Hey there, fellow food adventurers! Bella here, and boy, do I have a treat for you. As summer starts to fade and the cozy vibes of autumn start to creep in, I couldn't resist creating one last hurrah with my favourite summer squash: the mighty zucchini!

But forget boring, tasteless zucchini bread. We're talking a fudgy, chocolatey, vegan zucchini cake, with a creamy cheesecake swirl that will knock your socks off. Yes, you heard right - a cake that's both decadent and secretly packed with veggies!

The Great Cake or Brownie Debate

Okay, let's address the elephant in the room (or rather, the cake in the pan). Is this a cake, or is it a brownie? Well, it's a bit of both! The edges are perfectly cake-like, moist and fluffy. But as you journey towards the centre, things get deliciously fudgy and dense, like a brownie that's had a spa day.

So, whether you're a cake person or a brownie fanatic, this recipe is your perfect match. You get the best of both worlds in one single slice! Plus, it is packed full of goodness from the courgette and avoids dairy

The Star Ingredients

Let's break down what makes this cake so special:

  • Cashews: These little guys are the secret to our creamy, dreamy vegan cheesecake layer. Soaked to perfection, they blend into a smooth, tangy swirl of deliciousness.
  • Vegan Butter (or Coconut Oil): A touch of this adds extra creaminess to our cheesecake layer. If butter is not your thing, coconut oil works just as well!
  • Lemon: Zest and juice give our cheesecake that classic tangy kick. Don't be shy with the lemon – it's the perfect counterpoint to the rich chocolate below.
  • Zucchini: The unsung hero, adding moisture and a touch of goodness to our cake. Grate it coarsely and throw it in – no need to squeeze out any water.
  • Cocoa Powder & Dark Chocolate: We're going all in on chocolate here. Unsweetened cocoa powder plus chunks of dark chocolate create a rich, decadent base.
  • Baking Powder & Soda: The dynamic duo that gives our cake just the right amount of lift. They're not the same, so don't skip either one!

Get Baking: It's Easy Peasy!

  1. Cheesecake Magic: Blend cashews, vegan butter, sugar, plant milk, lemon juice and zest, and vanilla until super smooth. Set this creamy dream aside.
  2. Wet Ingredients Unite: Grate your zucchini into a big bowl. Add oil, sugar, and water, mix well.
  3. Dry Ingredients Assemble: Sift cocoa powder, flour, baking powder, baking soda, and salt into the wet mix. Gently fold everything until it is a smooth batter.
  4. Layer Up: Pour most of the batter into your pan, top with the cheesecake layer ensuring it goes to all edges. Dollop the remaining batter on top and swirl it to make it look pretty.
  5. Bake and Cool: Bake for 30 minutes, then let it cool completely before slicing and diving in. I find it is good to leave it overnight in the fridge, if you can wait that long, for a nice clean cut.
