Step 1

Grease and line a 20x20cm square tin with baking paper.

Step 2

Chop the Mars Bars into chunks approx. 1cm thick.

Step 3

Add the chopped Mars Bars and the butter to a large saucepan and heat on the low-medium temperate, stirring frequently until mostly melted. The nougat section of the Mars Bars will not melt completely but that’s ok!

Step 4

Pour the Rice Krispies into the saucepan and stir well until completely coated in the Mars Bar mixture.

Step 5

Spoon the mixture into the prepared tin and smooth it out into an even, compacted layer with the back of a spoon.

Step 6

Melt the chocolate in the microwave in 30-second bursts, stirring in between.

Step 7

Pour the melted chocolate on top of the Rice Krispie layer and smooth it out to the edges.

Step 8

Place the tin in the fridge for at least 2 hours or overnight.

Step 9

Let the traybake come to room temperature again before slicing to prevent the chocolate layer from cracking when you slice it.

Step 10

Slice into 16 squares and enjoy!
