Mars Bar Slice

Mars Bar Slice


Here we are again. Wednesdays seem to roll around super quickly and it stresses me out man. Here’s  another classic party recipe. If you don’t have Mars Bar Slice at your party then I am judging you so much. SO much. The best part is that even though it takes a little while to set completely, the rest is super quick and it only has four ingredients! So let’s jump into it?

What you’ll need:


3 x 53g Mars Bars (chopped)
90g unsalted butter (chopped)
3 cups of Rice Bubbles
200g milk chocolate (chopped)
30g butter


Melt the Mars Bars and the 90g of butter together in a saucepan. Go slowly and don’t try to rush it because you don’t want to burn either of these ingredients. You’ll find that the nougat takes a lot longer to melt down, but just keep stirring it until it’s as melted as it’s going to get.


Put the Rice Bubbles into a big heatproof bowl and then pour the Mars mixture on top. Stir it around a bit until it’s combined. I didn’t take a photo of this step but I’m sure you can work it out – I have faith in you.


Pour that mixture into a tin lined with baking paper. Then just chuck it into the fridge to set for a while.


Make the chocolate topping by melting the 30g of butter with the 200g of milk chocolate. You can do this in the microwave or on the stove. If you do it in the microwave, make sure you only do it in 30 second increments because the chocolate WILL burn very quickly. Even reduce it down to 15 seconds increments if you need to. On the stove top, boil some water in a saucepan and put a heatproof bowl over the top of the water. Put your ingredients in that bowl and stir until it’s liquidy. My chocolate ended up kind of lumpy and grainy and no one – not even my mum – could work out why. It tasted fine though, so we used it anyway. If you’ve mastered the art of caramel slice, you can use that topping instead – which I believe is chocolate and copha.


Pour it on top of the Rice Bubble mixture and then smooth it out as best as you can. Then leave it in the fridge to set completely for an hour or so before cutting it up to serve!
