Hello lovelies, do you also have so much zucchini in the garden and are you still looking for good recipes? Here is one for you: zucchini blondies with chocolate. I’m very happy that my zucchini grew so well in the raised bed this year. We were already able to harvest some. I don’t only like them savory processed but also sweet. And this is when these delicious blondies come into play. By the way, blondies are the opposite of brownies, as the name might already suggest. Blondies are missing cocoa and that’s why they are light.

Luckily nothing else is missing with the zucchini blondies with chocolate. They are super delicious, really juicy and of course contain some tasty chocolate. Nobody will notice that there are vegetables inside.

The blondies turned out really "fudgy", which is just the way they should be. If you don’t like it fudgy, leave them in the oven a little longer. By the way, I used a yellow zucchini for the recipe, but of course it works exactly the same with a green - except then maybe someone has questions about the ingredients. In case of using a yellow zucchini, it’s even less noticeable that vegetables are hidden in the dough.

Another great way to secretly make kids or other veggie disdainers eat some healthy veggies. Who could possibly say no to these delicious cuts? I already have another cake recipe with zucchini here on the blog. Have you already tried it?

Of course, there are already some savory recipes on the blog. We very much like the stuffed zucchini with lentils and orzo or the soba noodle salad, where I have replaced part of the pasta with zoodles (zucchini noodles).

If you're after more sweet ideas with hidden veggies, my zucchini baking corner has you covered: chocolate lovers will adore my moist Zucchini Chocolate Cake, the Zucchini hazelnut cake brings a lovely nutty note, and if you love chocolate paired with fruit you have to try my Chocolate cake with zucchini and cherries. I'd be so happy if you bake these blondies, and I can't wait to hear what you think.

TIPS

Verena's notes

A tip from my kitchen: squeeze the grated zucchini really well – the drier it is, the moister and fudgier the blondies turn out. Without oat flour, just use 250 g (2 cups) of spelt flour. Stored airtight, the squares keep for 3 days at room temperature and up to a week in the fridge, and they freeze beautifully. If you prefer them a little cakier, leave them in the oven for a few extra minutes.

GOOD TO KNOW

Frequently asked questions

  • No – the finely grated, well-squeezed zucchini disappears completely into the batter. It only adds moisture and juiciness without any flavor of its own. With a yellow zucchini in particular, nobody will guess there are vegetables hidden in the cake.

  • Blondies are essentially the pale sister of brownies: the batter has no cocoa, so they stay golden instead of chocolate-brown. Their flavor comes from vanilla, cinnamon and raw cane or coconut blossom sugar. In these blondies the chocolate shows up as chips in the batter and as a glaze on top.

  • Stored airtight, the blondies stay moist for about 3 days at room temperature and up to a week in the fridge. They also freeze well – ideally cut into pieces so you can thaw single portions. To serve, just let them come back to room temperature.

  • You don't need to peel the zucchini; the skin grates in finely and won't bother you. What matters is squeezing the grated zucchini firmly – by hand or in a kitchen towel. The less water ends up in the batter, the better the fudgy texture turns out.

  • Without oat flour, simply use 250 g (2 cups) of spelt flour instead of 150 g (5.3 oz.). For a gluten-free version, replace both flours with a gluten-free baking blend. Just make sure the baking powder and chocolate are gluten-free too.
