It’s been far too long since there was a Mars bar post around here. It’s also been far too long since I made brownies. The last time I made them was September! That just isn’t right. So I decided to finally get round to making Mars bar brownies, which have been on my to-do list for years (I’m not even exaggerating, literally years).
I’m also pleased to report that I can now do what most 7 year olds can do: melt Mars bars. Seriously, I don’t know if this is just me but I have tried to melt Mars bars loads of times and every single time it would turn into this funny lump that stuck to itself and left grease all round the pan. It was gross. And upsetting. Children melt Mars bars all the time to pour over rice krispies, but I can’t? How is that possible? Fortunately, I am now a Mars bar melting master.
These are definitely in the fudgy-brownie-camp. The Mars bars are melted with the chocolate and butter so that they are part of the brownie mixture, but then you also stir in 2 chopped Mars bars, so it’s a double hit of Mars bar! The stirred in Mars bars do melt away quite a lot, sometimes leaving only a ripple of caramel, so cut the chunks big. However, cut the two Mars bar brownies which are going to be melted with the chocolate reeeeeeally small. I cut them in half lengthways and then into pieces about 0.5cm wide. They melt easier that way! Now I’m off to scoff a few more brownies.
Mars bar brownies
A Cafe Lula recipe
Makes 36
Ingredients:
2 Mars bars (or Milky Ways), chopped small
200g/7 oz/1.75 sticks butter, cut into chunks
100g/3.5 oz dark (bittersweet) chocolate (about 72% cocoa solids), broken into pieces
100g/3.5 oz plain (semisweet) chocolate (about 50% cocoa solids), broken into pieces
65g/2.3 oz/ 1/2 cup + 2 tbsp cocoa powder
75g/2.65 oz/ 1/2 cup plain (all-purpose) flour
1 tsp baking powder
250g/8.8 oz/1 cup + 2 tbsp caster (superfine) sugar
3 large eggs
2 Mars bars (or Milky Ways), each sliced into about 10 pieces
Preheat the oven to 170C (340F) fan oven/180C (355F) conventional oven. Grease and line a 23cm (9 inch) square tin with baking paper. Cut the baking paper so that it hangs over the edges (this makes it easier to remove the brownies from the tin).
In a large pan, melt together the finely chopped Mars bars, butter and chocolates over a low heat, stirring frequently with a wooden spoon. Mash the nougaty bits of the Mars bar every so often with the spoon to help them along.
When the mixture is melted together and fairly smooth (other than some stubborn bits of nougat which won’t melt), remove the pan from the heat and allow to cool slightly. Pour in the sugar, then sift in the flour, cocoa powder and baking powder and stir them in until the mixture is well combined. Beat in the eggs until you have a smooth mixture, then fold in the slices of Mars bar.
Pour and scrape the mixture into the tin (it will be quite thick) and spread evenly around the tin, levelling the top. Bake for 30-40 minutes (mine took 37 minutes in a 170C fan oven) until a skewer inserted into the middle comes out with a few sticky crumbs on.
Remove the tin from the oven and place on a wire rack. Allow the brownies to cool in the tin until warm, then remove from the tin and cool on a wire rack. Cut into 36 pieces (or less if you like bigger brownies!).

These sound fantastic! Now if I could only find Mars bars here. They were in the stores when I was a kid but these days they can pretty much only be found sporadically or online. These however, look like one heck of a wonderful reason to hunt for some!
Thank you! 🙂 A world where Mars bars are difficult to find sounds too terrible to be real! I do hope you find some.
Chopped mars bar AND melted mars bars in the batter? OMG, this sounds so good!
Thanks! Yep, went a little mad with the Mars bars.
Oh man, a double hit of Mars bars? I’m in! I love Mars bars to death (they’re everywhere in Germany), and brownies too, so this would be a case of total self control fail.
Do it! Do it! 🙂
These sound absolutely amazing! 🙂
Thank you! 🙂
These sound absolutely fantastic. I love brownies of all kinds and when you add the Mars bars… mmmm!!!
Thanks! The Mars bars are ace for making the fudgy texture 🙂
These look like such gooey and perfect brownies!
Thanks! The Mars bars definitely helped them with their gooeyness!
I love mars. I love brownies. Both put together can’t be anything but divine.
That was pretty much my thinking when I decided to make them!
Those sound amazing. They are immediately on my to make list. Yum!
Thanks! I hope you like them 🙂
Aaaaaaand I’d kill for these too.
How rich do these look!!!!!! I would gobble them all up. I’ve never had a Mars Bar (I know, I know…under what rock is Tia living) but I am going to have to try one soon. It’ll be the closest I get to these brownies until I make them myself. Yum.
These look ridiculously amazing. Just ridiculous.
Good god, this is heaven. Milky Ways are my favorite candy. And brownies are awesome all on their own. I like that you melted them into the batter AND put chopped up bits inside. Double dose of delicious!
Milky Ways are my favorite – I would LOVE to try them with those. I am a sucker for a fudgy brownie every day!
Ooooh cannot wait to try these out!!
Am liking the look of your blog.
Might well even give you a heads-up on mine at some point soon – if you didn’t mind 🙂
I love putting chocolate bars in brownies…my favourite is Snickers but I’ve never tried Mars Bars so who knows….could become a new favourite (and by the looks of your pics is almost definitely will!). Yum.
These look super soft and so tasty! Thanks for the ingredients in grams too!
Oh gosh.. Even though i’ve just made some brownies myself, you got me wanting for more….
Even though I’m posting late, I win because I actually made these last night and can confirm that they are so nice that I did a little run on the spot, went to give my mom a piece to show her how nice they were, and then decided to eat it myself instead. You are too clever! 🙂 xxx
Hi!! i love your blog!!! just thought you might be interested in this !? its a company called the biscuiteers and they are having a bake off competition -id love to see you have a go http://www.biscuiteers.com/ice-off
what do you think of my ones!?
We had some MarsBars hanging around the kitchen, so I googled ‘Mars Bar Brownies’ and come across you… We are a family of self-proclaimed chocolate experts – we all agree these are the most amazing brownies we have ever come across. As my niece texted me from her morning tea at school – “Divine!”. Whilst we may have fought over who would eat the last one, all I can say is…’thank you’. Wow.
thankyou so much!!! luuuuurrrrved this recipe!!!!!!! i imade this last weeknd for my niece, she lOVED them!!!!! thankyou sooooooo much
I actually have to leave a post to thank you for your small chocolate glossary. I have been trawling the net for brownie recipes and the recipes I come across are in US measurements which are easy enough to convert, but their different terminology for chocolate was driving me mad. I’m making these tomorrow 🙂
Also I’m sorry that this comment comes three years after your post
