All the flavours of a Mars Bar in crunchy bar form. What's not to love?
Method
Line a baking tray with some greaseproof paper and set aside.
In a large bowl, melt the Mars Bars. Use the back of a spoon/spatula to break up the nougat, as this won't melt as well - don't worry about lumps though, it won't be perfectly smooth.
Add the rice crispies to the melted ingredients and mix well, ensuring all are coated.
Tip into your prepared baking tray and push down with the back of a spoon/spatula, ensuring an even finish right into the corners.
Melt the milk chocolate and butter in short bursts in the microwave before spreading over the top of your rice crispy base.
Artistically swirl your caramel over your chocolate topping.
