Mars bar slice

Mars bar slice is an easy no bake treat kids will love. With only five ingredients it’s the perfect introduction to cooking for little chefs.

Scottish Mars bar slice or Mars Bar cake is a bake I remember from my childhood here in the UK. I can’t remember making it, but I do remember eating it. There’s nothing healthy about it but if you want something really easy to make with your kids then this is a great option. Once you’ve melted the mars bars and butter (and you can do this in the mircrowave so there’s no need to use your cooker) you just need to stir it together with the Rice Krispies and leave it to set. What could be simpler?!

Difficulty: Easy

Time: 15 minutes plus chilling

Serves: 15

Ingredients

50g butter
1 tbsp golden syrup
4 regular (UK) sized mars bars (approx 200g)
3 cups Rice Crispies/rice bubbles (about 60g)
250g milk chocolate

How to make the mars bar slice

Grease and line a baking tin, approximately 19cm x 28cm.

Make the base of the mars bar slice

Measure the butter (50g) and golden syrup (1 tbsp) out and add to a small pan. Get your kids to chop the mars bars up and then add them to the butter.

Melt on a low heat, stirring occasionally until it comes together in a smooth chocolate mixture.

Meanwhile measure the Rice Crispies (3 cups) out into a large mixing bowl.

Mix everything together so the Crispies are all nicely coated with the melted mars bar.

Pour into the baking tin and press down with the back of a spoon. We found a metal spoon worked best for this as the mixture didn’t stick to it.

Leave for 30 minutes or longer to set.

Add the chocolate topping

Melt the chocolate in the microwave at short intervals, stirring to make sure it melts evenly. If you don’t have a microwave, put it in a metal bowl over a pan of simmering water to melt.

Pour the melted chocolate over the top of the Rice Crispies mixture and spread out with a spatula. Gently tap the baking tin on the counter to make sure the chocolate has spread evenly.

Leave to set again, before cutting into squares to serve.
