Mars Bar Slice Recipe
Crispy rice bubbles are bound by a rich, slightly chewy, chocolate-caramel mixture and spread with a luscious, buttery chocolate icing. This slice is very moreish!
This recipe uses 270g of Mars Bars. Here are three ways to get this amount-
264g bag of fun size Mars Bars (close enough!)
4 1/2 x 60g Mars Bars
3 King Size Mars bars, and half a 60g Mars Bar
Makes 18 pieces (each about 4.5cm by 6cm).
120g butter
270g Mars Bars
1 1/2 tablespoons (30ml) golden syrup
3 3/4 cups (120g) rice bubbles
Line an 18cm by 28cm baking tray/dish.
Place butter, Mars Bars and golden syrup in a saucepan over medium-low heat. Stir constantly, using the spoon to break up the Mars Bars and squash any bits of nougat that are slow to melt.
When the butter has melted and only small unmelted bits of nougat remain, increase the heat to medium, stirring constantly. The mixture may appear separated at first. Keep stirring until the mixture thickens slightly, and is fairly smooth and amalgamated. Remove from heat.
Place rice bubbles in a large bowl. Add Mars Bar mixture and stir to combine, trying not to crush the rice bubbles. Press mixture into prepared pan and refrigerate while preparing the chocolate icing.
Spread slice with icing and refrigerate until set. Cut into pieces to serve. Store in an airtight container in the refrigerator.
Rich Chocolate Icing
225g milk chocolate (we use Cadbury Dairy Milk chocolate)
45g butter
Melt chocolate and butter over low heat, stirring occasionally. Remove from heat when mixture is smooth. © www.exclusivelyfood.com.au

Thankyou so much Amanda and Debbie. So easy and so delicious. A real favourite!!
So yummy. Put leftovers from party in the freezer in an empty icecream container and still tasted just as yummy when thawed!
Thankyou the kids thought this was great.
Thank-you for the recipe. It was very yummy, kids loved it!
Yummy Yummy!!! I made it for my year 7 camp and they all loved it
The pics looked heavenly and too good to be true....... well actually they tasted even better than what they looked like which is quite amazing considering any time i look at the pics my mouth drewls....mmmmmmmmmmmmmmmmmmmmmm..
For a really indulgent slice try substituting Coco-pops for the rice bubbles - it works really well
Put heaped tablespoons of the mix into foil fairy cake cases and top with melted chocolate to make individual mars bar slice "bites". Great with after-dinner coffee.
Had these before when a barbecue visitor brought some round. She was australian and wouldnt tell us how she made them as she told usit was a secret australian recipe. Thanks very much, im sure ill be making these all the time.
these are really good. i love making them too. i want one right now
add half a pkt of marshmallows into the melting pot - makes this delicious slice even gooyier and chewier!!
A friend of mine made your recipe and she used it for a subject of an essay. She also decided to make some and bring it into the classroom. Luck I was there that day because I got to have a taste test and it was the best thing I had ever had. I wanted more and more but it was all gone:(
Thanks a lot for this recipe it was yummy. ;) five stars!
just found your site been on for hours i am so hungry i have to make something out of awesome recipes thanks
Thankyou so much for the recipe! Didn't have the golden syrup so just didn't add that in, but the slices turned out perfect anyway. Brought them along to a girls night in and my friends all thought they were amazing. I'll definitely be trying out more recipes from this site.
Loved this recipe but was wondering if it was cooking chocolate you used in topping?
We use eating chocolate in the topping, but cooking chocolate could be used if preferred.
I have made this 3 times and it is delicious every time.
I have taken the advice of one anonymous comment to omit the golden syrup for two of times I made the slices and they indeed taste better...to me. Apparently, the toffee-ness from the Mars bars are just right without being overly sweet.
Just one quibble though...the rice bubbles turns out more chewy (in a good way) rather than crispy (as mentioned in the introduction) for all three times. Is that how they are supposed to be? Or am I doing something wrong? Also, what's the best way to cut these slices without chunks of those toffee goodness sticking to the knife?
We find that the rice bubbles retain most of their crispiness for at least a couple of days. Apart from omitting the golden syrup, do you make any changes to the recipe?
Once the slice is cold and set, we cut it with a hot, dry knife.
Hey, love the recipe me and my wife love it!
Only qualm is that every time we go to make the chocolate icing it turns into a gritty, paste like substance instead of being smooth. What are we doing wrong? :P
Hi Jake,
Did you melt the chocolate and butter over low heat? Overheating can ruin the texture of chocolate.
Erm. Define low heat :P ahaha, because that's probably where we've went wrong...
mmm...
i havnt made it yet coz we dont have any rice bubbles what could you use instead??
Do you have any Coco Pops?
Hi Jake
We have an electric cooktop and use the lowest possible setting when melting chocolate. If you are unable to achieve a very low heat level with your cooktop, you could use a bain-marie when making the icing.
thankyou so much for the recipe, it was a real hit in the staff room at work.
We did have trouble with melting the chocolate, second time round we melted it in a bowl over boiling water.
Jake
Are you using chocolate 'melts'? If this is the case omit the butter, you dont need it as the melts are made especially to melt smooth like the consistency obtained with eating choclate and butter - I learnt this by making the same mistake :)
delish!!! they tasted even better than the recipie i use:) I took them to a work christmas party and the were a hit! will be making these again very soon.
5 stars :c)
I made this Mars Bar slice over the weekend and took it to a mates house as we had a play date with the kids. And everyone loved it! And the pieces i managed to claw out of their hands and take home my family loved also. =) Thanks for the recipe, it was beautiful!
just this second put mine in the fridge to set! they look sooooooooooo good!!! :)
Hi, i already knew this recipie but a bit of advice whip up some cream and presto its even more delicious than before!!
thanks!! my daughter was making this for a school bake sale but i forgot the recipe!! ur lifesavers!!
About to make the Mars bar Slice, can I use Nutri Grain or a Plain Label Version which is a bit smaller in size and less sweet, but more crunchy. What do you think? Thanks for having it on Line. Lee
Hi Lee
We wouldn't use a Nutri-Grain type cereal as a substitute for the rice bubbles. However, if you decide to try it, we recommend that you chop or crush the Nutri-Grain into pieces about the size of a rice bubble.
Re: Jake's problem with the gritty chocolate...
I make it up and just use a ganache icing - microwave a 250g block of chocolate and 1/3 cup cream on low, stirring periodically, and presto-- smooth creamy ganache!
