Mars Bar Slice Recipe – the ultimate childhood throwback

Mars Bar slice recipeSo I have a confession to make – up until this week I had never made or eaten Mars Bar slice. NEVER!  It’s not the kind of dessert my mum would ever have made as a kid, and up until year 5 I went to a school where we never really had sugar. Carob was our chocolate. So I was just as excited as Tully to make this Mars Bar slice recipe! I was always jealous of the kids who had it in their lunchbox!

We are online learning at the moment so this counts as a maths and food tech lesson lol.

Mars Bar Slice Recipe

Step 1

Melt the Mars Bars, butter and maple syrup in a saucepan over low heat. Stir continuously until it is completely melted.

Step 2

Measure and pour Rice Bubbles into a heat proof bowl.

Step 3

Pour chocolate mixture over rice bubbles.

Step 6

Line a 20×20 inch tin and press the mixture into it. All the way to the corners.

Step 7

Melt the cooking chocolate and pour it over the top of the mixture in the tin. Make sure it reaches all the sides.

Step 8

Refrigerate for 3 hours.

Step 9

Slice into squares using a hot, dry knife. I run the knife under hot water for about a minute then dry it. A hot knife will cut through the chocolate without cracking it.

If you want these thinner, then use a slightly larger tin. I shared these on my stories and one follower shared that she makes them with Coco Pops instead of Rice Bubbles. I’m here for it!
