Easy and fudgey Mars Bar brownies! So chocolatey, so delicious!
Mars Bars brownies
It’s the time to have something so chocolatey, that you’ll want to make them again and again. These Mars Bar brownies is exactly that. So unbelievably chocolatey and fudgey they are on a next level. Are you intrigued yet?
Anyway. I thought I would start this recipe post off with a statement that makes you go these MUST be good, and then you’ll see the pictures and be like oh heyyy look at them, yes, they are amazing. And I really hope you guys did because I certainly did.
Mars bars and Milkyway bars (US)
From the beginning I must say that Mars Bars in the UK, are Milkyway bars in the US, so if some of my American readers are a little confused right now, just roll with a Milkyway instead. I finally found out why there is a different in name the other day (due to a family spat back in the day), and I was surprised that that was all it was.
Even so, Mars Bars are the one. They are slightly underrated in my opinion, but I do adore them. For those who have never experienced the wonder that is a Mars Bar… they are nougat and caramel, coated in milk chocolate. They are delightful.
Mars Bar recipes
When I was thinking about what chocolate bars I should bake with, I wanted to use one I hadn’t tried in a while. I’ve used Mars Bars four times on this blog already, my favourite time being my Mars Bar cheesecake, but it was so long ago!
These brownies came about because of my craving for something Mars Bar, and also because they were on offer in the supermarket I was in at the time so that made the bake cheaper. Always handy in my books. I couldn’t resist!
Dark chocolate
I went for a classic style brownie, that I have used in so many recipe posts now. And I will say it time and time again, PLEASE USE DARK CHOCOLATE IN THE BROWNIE MIXTURE. I don’t really care if you ‘don’t like dark chocolate’ it will make such a good brownie, and not too ‘dark’ a flavour, so PLEASE stick with it.
If you use milk chocolate, the mixture is so much thinner, and when people moan to me that their brownies didn’t bake properly, and say they switched to milk chocolate then that is why. It doesn’t work the same, and doesn’t make them nearly as fudgey. Dark chocolate is the best.
Brownie
The key really is to make the brownie mixture as thick as possible, and dollop on all your Brownie bits. When the caramel and nougat bakes, it’ll make little pockets of deliciousness for you to enjoy, and they are just a combination to behold. SO tasty!
Freezing Mars Bars
I realise its a faff, but freezing the Mars Bar bits before baking really is the best practice so they don’t explode everywhere completely and utterly, but its not completely essential. However, if you can, I would 100% recommend it!
These brownies are so fudgey, so moreish, and delightful. I really hope they live up to your expectations for my latest Mars Bar creation! Enjoy! X
Mars Bar Brownies!
Ingredients
Brownies
- 200 g dark chocolate
- 200 g unsalted butter
- 3 large eggs (or 4 medium)
- 275 g light brown sugar
- 100 g plain flour
- 50 g cocoa powder
- 300 g Mars Bar (chopped & frozen)
- 100 g milk chocolate chips (optional)
Optional Decoration
- 50 g milk chocolate (melted)
- Mars Bar pieces
Instructions
- Preheat your oven to 180C/160C Fan and line a 9x9" baking tin with parchment paper!
- Melt together your dark chocolate and unsalted butter until smooth in the microwave or in a bowl over a pan of simmering water. Leave to cool for a few minutes
- Using an electric whisk/stand mixer, whisk your eggs and sugar together for 5 minutes or so on high speed, or until the mixture has doubled in volume, is alot paler, and leaves a trail for a few seconds when you lift the whisk out.
- Pour in the chocolate/butter mix and fold through very carefully.
- Add in the flour and cocoa powder and fold through carefully again.
- Add in your frozen chunks of Mars Bar and chocolate chips and fold in. Pour the mixture into the tin and bake in the oven for 25-30+ minutes.
- Leave to cool in the tin, and then enjoy!
- To decorate your brownies if you fancy it... melt your chocolate and drizzle over the brownies, and add pieces of Mars Bar to each one! Set in the fridge, then chop up and enjoy!
Notes
- Please try and freeze the Mars Bar first as it'll work so much better!
- These will last for one week+!
- You can use caster sugar instead of the brown sugar, the brown sugar just works really well for the Mars Bar theme!
- If your brownies are taking much longer than stated to bake, your oven may have been the wrong temperature, or you over mixed your batter. Keep adding on 5 minutes till they're done and cover with foil if need be!
ENJOY!

I’ve started baking some of these recipes and taking them in for the lads at work, I started baking for 4 of us, word got around and my latest bake was these and for 20 people! These were their favourite bake yet! So yummy!
Thanks for sharing this wonderful recipe. Can’t wait to bake them. I have 2 queries. You have not used baking powder so curious to know if the batter will rise and be soft without it? Also can I add milk in the batter to make it soft as I do for my regular brownies? Thanks!
This recipe does not need milk, or baking powder – trust me!
These were absolutely spot on, so delicious and perfect in every way. Especially eaten warm – they reheat well in microwave for 20-30 seconds and they go warm and gooey with the caramel melting. Fab recipe, definitely recommend and will 100% be making again
Hi Jane,
I was wondering can I use this recipe as a base to make a boost brownie and a snickers brownie? I haven’t made this recipie but I made your kinder bueno brownie at the weekend and it was hands down the nicest thing I have ever made! Thank you for all the hard work you put into your website and recipie creation. I really appreciate all these fantastic recipies that I can access!
Yes!! Just follow the same idea for the mars bars and freeze the boost/snickers! x
These are the BEST brownies!! I have had numerous requests for these and friends/colleagues say they are the best they’ve ever tried! They went down a treat in the staff room! I now keep all the ingredients in the cupboards so can make whenever! Thanks for the straight forward and clear recipe, cant wait to try some of your others! x
Hi Jane just tried your recipe I find I have to bake a little bit longer . But the question is why do mine sink a little bit in the middle please . There taste absolutely amazing by the way kind regards Joyce
That can be a few things – but sometimes it’s the whisking/folding isn’t quite right. Try being careful when folding the rest of the ingredients into the eggs/sugar! x
I don’t know what I did wrong, other than not freezing the mars bars ( but short on time). The crust on the top detached from the brownie, I don’t know what I’ve done wrong.
Smells yum though, am sure my kids won’t care!!
That sounds a little over whisked maybe? x
Does this recipe work well gluten free or should I add xanthan gum/cornflour?
Yes you can just use gluten free flour! x
HI Jane
Can I use 100g of dark chocolate as that’s all I have?
Thank you in advance
For the base brownie? No you need the 200g x
Wonderfully delicious again. Always have goos reviews. Is there an alternative recipe for someone who is Celiac? They always miss out!
You can swap all ingredients for gluten free and they should work the same!
Absolutely delicious. Mine took longer to cook but they turned out the perfect brownie texture in the end; soft, fudgey and slightly gooey. I need to make a second batch ASAP!
Hi can these brownies be frozen once they are made? Love your recipes!
Thanks
Nicola
Yes they can!!
Hi can I use salted butter? Will it make a difference?
Just means it may taste slightly salty/less sweet!
Hi Jane! Love making your recipes, I was just wondering how long you freeze caramel chocolate for and if you also freeze those pieces if you’re adding them to the top? X
I would say at least an hour so it’s completely solid (if they’ve already been chopped) but it doesn’t matter if they’re in there for longer x
Hi,
I tried this recipe and it was absolutely delicious! Just wondering if you could make this with Reese’s Minis and Reese’s Cups on top?
I’m obsessed with all Reese’s products and my family is too! X
Yes you can! X
Hi Jane,
I want to use Cadbury’s caramel chocolate bar, should I freeze it? Or will it not need it?
Thanks ☺️
I would freeze it, yes!
Hi Jane, would I be able to swap out mars bars for twix? if so would I still have to freeze them?
Thanks!
I would just to be safe, yes, as they have the caramel! x
