Hello lovelies, today I'm sharing a real heart's favorite with you: my zucchini chocolate cake. When summer rolls around and the zucchini grow faster than we can eat them, one almost always ends up in a cake here – and this is the one my girls ask for most often. The best part: you don't taste a hint of the vegetable, only moist, deeply dark chocolate.

That's exactly the little magic trick. The finely grated zucchini releases its moisture into the batter, and instead of a cake that dries out quickly you get a crumb that stays soft for days. I used to bake it with butter and eggs – since I make it vegan with spelt flour, coconut blossom sugar and oil, it has become even moister.

Zucchini

Zucchini is one of the most rewarding baking ingredients there is. 250 g (8.8 oz.) finely grated disappears completely flavour-wise, yet brings exactly the moisture that makes a chocolate cake irresistible. You don't need to peel it – the only thing that matters is that after grating the zucchini draws out water, and I always squeeze that out well before folding it in, so the batter stays light instead of heavy.

For the chocolate side I work on two levels: cacao in the batter for depth, and 50 g (1.8 oz.) of roughly chopped dark chocolate that melts into little pockets while baking. A few chopped almonds add a gentle bite, and the zest of half an orange rounds it off. That subtle citrus note is the icing on the cake for me – I simply love the combination of the tart orange and the sweetness of the chocolate.

If you want to turn the cake into a real showstopper, coat it with a thin chocolate glaze and decorate it with home-dehydrated blood orange slices. I dry them thinly for a few hours at a low temperature until they are almost translucent. It isn't necessary – dusted with a little powdered sugar it's just as delicious – but on a coffee table it looks especially beautiful this way.

It bakes at 180°C (356°F) for about 40 to 50 minutes. I like to take it out a touch earlier, because we love it when the middle is still really fudgy and moist. The next day, once it has settled, it tastes almost even better – if there's any left at all.

If you love this zucchini chocolate cake, you'll adore my other zucchini-and-chocolate ideas: for a fruity twist reach for my chocolate cake with zucchini and cherries, if you prefer something smaller and bar-shaped bake the zucchini blondies with chocolate, and for the orange-chocolate pairing in its purest form I recommend my chocolate brownies with an orange chocolate mousse. I'd be so happy if you bake this cake – let me know how it turned out for you.

Yours, Verena

TIPS

Verena's notes

Tip from my kitchen: squeeze the grated zucchini really well before folding it in – that keeps the cake moist but never soggy. Covered, it keeps for 3 to 4 days and, once it has settled, tastes almost better on the second day. You can use raw cane sugar instead of coconut blossom sugar, and if you can't get blood oranges, dry regular orange slices or skip the garnish entirely. A thin chocolate glaze makes it festive, but it isn't needed – it's lovely and moist on its own.

Frequently asked questions

  • No, and that is exactly the trick. The finely grated zucchini only adds moisture and a soft crumb, while its flavour disappears completely behind the chocolate. Even the kids here have no idea there is a whole vegetable hiding in the cake.

  • Covered, the cake stays moist at room temperature for 3 to 4 days – thanks to the zucchini it barely dries out. In warm weather, or to keep it fresh longer, store it in the fridge, and individual slices freeze well too.

  • You don't need to peel it, the skin disappears completely while baking. What matters is squeezing the grated zucchini well after it has drawn out water, so it doesn't make the batter too wet and the cake stays nice and light.

  • Yes. Swap the spelt flour 1:1 for a gluten-free flour blend that contains a binder. The cake turns out a touch denser, but thanks to the zucchini it stays pleasantly moist.

  • No, the orange slices are just a pretty garnish and completely optional. Without a dehydrator, simply dry thin slices for a few hours at your oven's lowest setting (around 70°C / 158°F) with the door slightly ajar – or leave them off altogether.
