Zucchini Chocolate Brownies

These delicious and unbelievably soft Zucchini Chocolate Brownies are fabulous for freezing and popping straight into the kid’s school lunchboxes – plus they contain hidden veggies!

Did you know there is a specific day of the year to celebrate Chocolate? It’s July 7th, but I figure any day is a good day for chocolate! I am more than happy to celebrate the deliciousness of all things chocolate… white, milk, dark and everything in between. There are so many ways to eat chocolate – as a block, in ice-cream, biscuits, cakes, or a yummy brownie!

Chocolate zucchini brownie recipe

One of my kids favourite baked chocolate treats is brownies. There are many variations out there with nuts and fruit, but I made a version sneaking in zucchini, which made the brownie richer, more moist and ooh so yummy!

All you’ll need is a few simple ingredients from the pantry, plus 2 zucchinis. I used coconut oil as it can have positive effects on your health such as improving hair, skin, cholesterol, immune system and more. I use it in many of my bliss ball recipes too.

This Zucchini Chocolate Brownie recipe is fabulous for freezing and popping straight into the kid’s school lunchboxes. I like to make a few batches in bulk, slicing them up, and then freezing in individual portions ready for the lunchboxes (or an afternoon snack!).

Wow! What an amazing concept! I always try to sneak veggies into our dinners, but not for one second did I ever contemplate adding goodness into treats! This is now on my list for baking this weekend. Thanks Kat!

Yes the zucchini makes most muffins really moist, I’ve made some chocolate zucchini muffins in the past, don’t think I have blogged the recipe yet, but they too were really good! Hope your kiddies like them!

Thankfully I had all the ingredients in the pantry and some extra zucchini and made it this morning, the kids had a slice with a glass of milk and they really enjoyed it, got a winner here.

Katrina - The Organised Housewife July 7, 2015 - 2:05 PM

That’s great they loved it, mine really enjoyed it too, I love how moist it is and a little extra hit of chocolate with the choc chips.

Great idea using zucchini! It’s such a mild flavoured vegetable so it would fit in well. I once made spinach ones-the spinach flavour only disappeared when they were cool!

Kat, I was wondering how much grated zucchini would be needed as I have some in my freezer from the summer glut & I would love to make the brownies.

Hi Mary, I used 2 zucchinis. I have never thought of freezing them, did you freeze them grated or whole, do they freeze well?

Mary July 9, 2015 - 8:48 AM

Hi Kat,
Apologies for my second comment & email I think my iPad has a glitch!

I grate my zucchini to freeze, very handy to have for winter when these veggies are dearer & they freeze very well. I just wash them well & then grate! Voila. I freeze in cup measurements.
However not very handy when I don’t have cup measurements for a recipe!
I think I might try with 11/2 – 2 cups & see how I go.
Thank you.

hi Kat.
I don’t know what happened to my comment yesterday so I will try again!

I am wondering how much the grated zucchini would be as I have plenty in my freezer from the summer glut & would love to make the brownies.
Thank you.

I also sneak vegetables into muffins, I found a great recipe using beetroot, almond meal, carob, coconut oil . So simple, sweet and no sugar .
