You would never know these delicious decadent brownies have courgettes in them and so far, friends and family haven’t had a clue what either of the secret ingredients are: the courgettes to add an extra moistness (essential in a brownie); the espresso powder to enhance the chocolate flavour, giving an extra chocolatey taste with no hint of coffee.

I love courgette season but OH doesn’t look forward to the masses of his least favourite vegetable turning up everywhere. So, after plenty of ratatouille, roasted courgette quiche, courgette soup, Smoked Salmon with Courgette Savoury Cake, lasagne and Courgette and Ginger Jam, OH was pleased to try courgette in a brownie. I hate to waste food even if the courgettes are growing so fast there are enough for the compost heap, so these Courgette Brownies are a great asset in what OH describes as “The Courgette Wars”.

I hope you enjoy these courgette brownies as much as we do.

  • 300 g courgettes / zucchini
  • 1/2 teaspoon salt
  • 200 g plain chocolate broken into small pieces (I used 70% cocoa)
  • 150 g butter
  • 3 eggs
  • 200 g caster sugar
  • 1 teaspoon vanilla extract
  • 150 g plain flour
  • 1/2 teaspoon bicarbonate of soda
  • 2 teaspoons baking powder
  • Optional: 2 teaspoons espresso powder
  • Optional: 100 g chopped nuts (I used hazelnuts)
  • Step 1 Preheat oven: 180°C / 160°C fan / gas Mark 4
  • Step 2 Grate or shred your courgettes / zucchini before chopping the courgette into smaller pieces.
  • Step 3 Place in a colander inside a bowl and sprinkle with salt. Leave to drain while you get on with the Brownies.
  • Step 4 Place the chocolate and butter in a microwaveable bowl and microwave on high for 1 to 2 minutes in 30 second bursts until melted. Add the vanilla extract and stir until chocolate is nice and smooth and leave to cool.
  • Step 5 In a large bowl, whisk the eggs and sugar together using an electric mixer until doubled in volume (about 5 to 8 minutes depending on your mixer)
  • Step 6 Pour the cooled chocolate mix into your egg mix carefully and gently fold together with a silicone spatula.
  • Step 7 Fold in the courgettes (and nuts if using) in a figure of 8 movement. Take your time, you don’t want to knock the air out.
  • Step 8 Hold a sieve over the bowl of your chocolate mixture and sieve over the dry ingredients. Carefully fold in using a figure of eight movement.
  • Step 9 Pour mixture into the prepared tin, gently easing the mixture into the corners of the tin and levelling with a spatula. Pop in the oven for 30 minutes.
  • Step 10 Check to see if there is a paperlike crust on top – there should still be some movement in the centre of the tin. If it’s not ready, bake for another 5 minutes.
  • Step 11 Remove from the oven and leave in the tin until completely cold – if you can !
  • Step 12 Using the extra parchment paper edges, remove from the tin and cut the into squares and dust with icing sugar.


  • You will need:
    1 baking tin 27cm x 18cm (11″ x 7″) lined with baking parchment (with a 5 cm overhang of parchment for easy removal of brownies)
  • To check you have achieved enough volume with your eggs and sugar. Remove your whisk, if there is a trail on the surface of the mixture for a second or two, it’s done.
  • Will keep in an airtight container for up to a week, freezes well too.

If you’re lucky enough to have a bumper crop of courgettes, why not try making my Spicy Courgette Chutney or delicious Courgette & Ginger Jam?

  • These brownies are absolutely heavenly. Like the best brownies in the best cake shop in the world. We’re having them warmed for 15sec in microwave and with some yogurt poured over. Thanks so much for aiding the use of the fourth marrow in my veg box this month. I’m making these again!

    • Thanks Sue, so pleased you enjoyed our courgette brownies as much as we do. What a good idea to warm them, I think I’ll have a go at 15 seconds in the microwave.

    • Hi Anne, thanks for getting in touch. The info didn’t get put into the updated printable recipe, will update the post.
      You will need:
      1 baking tin 27cm x 18cm (11″ x 7″) lined with baking parchment (with a 5 cm overhang of parchment for easy removal of brownies)
      Let me know how you get on 🙂

      • Thanks for the tin size. I actually used a deep 12 “x 8” as my 11×7 didn’t look deep enough and I was right! It was the perfect size.
        I have to say this is the most moreish cake I’ve had in a while. It is sooooo moist and sticky. Even my grandson who made the cake with me and was disgusted at the thought of courgettes in a cake, couldn’t get enough down his throat fast enough!
        Mine doesn’t have a crispy top but a sticky top like gingerbread.
        I didn’t use 70% chocolate. I used a cheaper 50% chocolate and 30grams cocoa powder.

        • Hi Anne, I’m so pleased you and your grandson enjoyed my courgette brownies. Courgettes vary in how watery they are so maybe that affected your crispy top and ovens vary so perhaps try leaving the brownies in the oven for a little longer. It sounds like you had a lot of mixture so that would affect cooking time too. Mind you if you enjoyed them as they are I wouldn’t change what you’re doing 🙂

  • Wow, courgette in brownies sound super interesting and healthy too. Love the idea, especially when kids are fussy eaters, like mine.

    • Thanks Sapana. My kids have grown up but I do have a husband who’s a fussy eater and can sympathise 🙂

  • I love using zucchini for baking as they add so much moisture to the cake and I bet it’s the same with these delicious and fudgy brownies! Looks yummy!

    • Thanks Gail, you’re right using zucchini/courgettes does add to the moistness in any bake and makes it so easy to get the squidgy centre that is essential in a brownie.

  • I’ve been meaning to try courgette brownies just to try something new and these look so good! Now I really want to make them. I’m not such a big fan of chocolate, but when you add courgettes I don’t think I would mind it! Healthy and chocolate is a perfect combination for me! I will definitely need to try this out one day. Thank you for sharing this recipe.

  • I recently took up an allotment and given the extra space have grown more courgette plants than ever before and i can’t even give them away! I made this recipe on Saturday evening for a family picnic yesterday. They are absolutely divine! I’ve made courgette brownies before but this will now be my go to recipe! Like yours, my husband is not overly keen on courgettes but he can’t tell they are in this! Really lovely. Thank you.

    • Thanks Rachel, so pleased my brownie recipe will be your go to recipe. Glad to hear I’m not the only one with a husband who’s not keen on courgettes 🙂

  • Fun recipe to make, fun to share! Little question — when to add the vanilla, I just added it after the chocolate, the recipe doesn’t note. FYI.

    • Thanks for getting in touch Gloria. Sorry it’s such a late reply but I’ve been on a break from my blog. You add the vanilla extract to the melted chocolate and butter, recipe is amended 🙂

    • Hi Pat, sorry for the late reply but I’ve had a bit of a break from my blog. My courgette brownies freeze really well.

  • I made these for my family and work colleagues. They went down a treat. I included the hazelnuts. So easy to make. I will definitely be making them again 😀

  • I plan ongiving these a go as my son loves brownies and it is an endless battle to get vegetables into him! I have baked some sweet marrow muffins this week and as courgettes and marrows are related may well give it a go substituting marrow as there is a bit of a glut of them here!

    • Thanks for stopping by Sarah. Marrows would be fine in the brownies, you might want to discard the inner stringy seed middle you get when courgettes get too big. Giving the grated large courgette/marrow an extra chopping would be an a good idea too as marrow skins can get a bit tough. Let me know how you get on.

  • My attempt at this recipe wasn’t very successful, it exploded out of my 7 X 11″ tin and still looks very soggy after 45mins, should there be some flour in this recipe?

    • I am so sorry Roz. You are absolutely right, there is 150 g of plain flour missing from the ingredients list. Please accept my apologies for your wasted time and ingredients, I feel terrible as I do proof read my recipes, in this case I simply don’t know what happened.

  • These brownies looks superb Sarah and just what a brownie ought to be like. I’ve made courgette brownies before and they were good, but not nearly as good as these look. I’ve been making quite a few courgette fritters and pancakes – they are delicious and I defy anyone to dislike them. Something else to try OH with maybe? Thanks for joining in with #WeShouldCocoa.

    • Thanks Choclette. that means a lot to me, I must admit I was a little nervous submitting a brownie recipe to the ‘Brownie Queen’ 🙂
      I like the idea of courgette fritters, definitely one to try on OH! Always a pleasure to link up with #WeShouldCocoa , I’ll try not to leave it so long next time.

  • Those look delicious and sound so healthy Sarah! Since I don’t cook with eggs, I would probably have to try this out with an egg substitute, but I will definitely be trying it out soon. 🙂

  • What a great way to hide some veggies in a decadent treat. Wonderful recipe and man do I want some chocolate now. Can’t wait for a glut of zuc’s now.
    Stopping by from Fabulous Foodie Fridays.

  • Yum! I’ve heard of zucchini brownies before, but I’ve never made one myself. These look rich and tasty! I love your kitchen tips and how you introduced us to your culture by describing the “The Courgette Wars.”

    Thank you so much for bringing these to the fiesta this week! Happy FF, and have a fabulous weekend!! 🙂

    • Thanks Kaila, I’m not so sure OH is pleased I’ve introduced “The Courgette Wars” to everyone but I’ve got some more recipe ideas to keep him happy.

  • Yummy! Great to hear OH loving these brownies 🙂 It really is a great way to work away all the courgettes! Thanks for sharing them at Fiesta Friday!

  • These look absolutely tasty! I always love to see how I can “hide” vegetables in sweet treats! I actually saw a black bean and avocado brownie recipe. Thanks for sharing!

    • Thanks Bobi, black bean and avocado brownies sounds interesting, I’ve tried avocado and chocolate mousse, it was delicious.

  • I adore baking with courgettes… the bake just gets moister and moister the longer you leave it… not that these brownies would last very long in my house, they’re stunning! Thanks for linking to Simply Eggcellent!

    • Thanks Dom, brownies don’t last long at the Kitchen Shed either. A pleasure to link up with Simply Eggcellent, look forward to your round up 🙂

    • I’m not so sure I would say healthy brownies, lol but they are delicious. Let me know how you get on x

  • How interesting, I never would have even put courgette in the same sentence as brownies let alone in the same recipe but I’m curious to try it! Thanks for sharing.
