It’s not often that you read ‘chocolate, courgette and blueberry’ in a sentence, let alone an ingredients list…but here is my Chocolate, Courgette & Blueberry Brownie.
Excess Courgette Harvest
I had excess harvest last week and had given a bundle of produce away to anyone who was passing. A little timid at first, one or two passionfruit were taken, followed by a cucumber, a pocketful of pears, handfuls of tomatoes…then to my surprise, a recipient gave me a large yellow courgette to say thanks! I grinned. Little did he know I had a garden full of courgette to tend with, but the intention was very lovely!
So, with an extra courgette milling around my fridge (verging on a marrow really, it was pretty huge) I decided to do some baking.
I had great success a few years ago with the making of my Chocolate Courgette Cake and wanted to experiment further with a brownie. So, inspired by nutritionist Claire Turnbull (who always endeavours to offer healthy recipes), I proceeded to mix both fruit and veggie into a brownie to defy all odds. Not only would my very large yellow courgette be grated skin-on, I would also add blueberries to the mix. In theory, it would work and in actuality, it rocked!
Dairy-free, it could well be gluten-free too by using gluten-free flour.
This is a very moist and chocolatey brownie, but not over-sweet. Don’t be fooled by the courgette, you will hardly notice it there (and certainly won’t be able to taste it).
TIPS:
- If you are looking to use a big old marrow, you may wish to remove the skin before grating the flesh in case it is a little tough. Personally I would discard the seeds in this instance once grown to mature marrow size!
- If using courgette, top and tail it, then grate it all. The skin and seeds are soft and work well.
- Be sure to squeeze the grated courgette/marrow in your hands to remove as much liquid as possible. The brownie is already very moist and doesn’t need extra liquid!
- I have experimented with this recipe several times. In one baking session I found I was running low on flour, so topped up the 1.5 cup requirement with ground LSA (linseed, sesame and almond). It worked a treat too!

Hello, can I use marrow in these?

Hi Deborah, yes definitely. Grate the marrow (as you would courgette) and measure 2 x cups. The result will be the same. Happy baking! >>Julie
