Mars Bar Slice

I’m not the kind of girl that will walk into a supermarket and buy a Mars Bar to eat (not that there is anything wrong with that, I just usually choose a Turkish Delight instead!). Add to that the fact that I never really eat a bowl of Rice Bubbles for breaky (I’m more of a muesli girl). BUT I do NOT ever stick my nose up at eating Mars Bar slice. Never ever. Scroll down to watch my video and you’ll see why…

 

So what is it about Mars Bar Slice that makes it sooooo darn good?

A) You don’t need many ingredients – which is great for people like me who even when armed with a grocery shopping list still somehow manage to forget things!

B) It’s super fast to make… I’m talking 10 minutes!! Perfect for when you have other important things to do like cook dinner, fold washing… and watch Netflix!

C) You don’t even need to turn on the oven (which means you can spend your electricity bill savings on shoes… done. done and DONE!).

D) It’s so easy that you could virtually make it with your eyes closed – go on, try it… I dare you!

But seriously, if you’ve never tried to make Mars Bar Slice before, you have no idea what you’re missing out on… it’s freaking AMAZING!!!

On a random side note, I saw a piece of Mars Bar Slice in a cafe on the weekend for $4.50… for one teensy piece! Two pieces would have paid for the ingredients to make a whole slice. Crazy stuff!!! And anyway, everything tastes better when it’s homemade, don’t you think?

Notes

Recipe Notes
Melting the butter, golden syrup and Mars Bars - you can melt the ingredients in the microwave, on the stove-top or in a Thermomix. Note: The Mars Bars will not melt completely but will still in small chunks – this is fine. 
Press the mixture VERY firmly into a greased and lined baking tin - The mixture needs to be pressed down very firmly so that it doesn’t break apart you you cut it.
Adding coconut oil or vegetable oil to the milk chocolate - will help it to stop from cracking when sliced. 
Setting time - Leave in the fridge to set for a minimum of 3-4 hours (overnight is best). 
Cutting the slice - Take the slice out of the fridge 30 minutes before cutting to allow the chocolate to soften slightly. Use a small serrated knife to cut through the chocolate layer and then through the rice bubbles layer. 
Storing the slice - Mars Bar Slice can be stored in an airtight container in the fridge for up to 1 week. It can also be frozen for up to 1 month. 
Golden syrup substitutions - You can replace the golden syrup with corn syrup, honey or maple syrup.
