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.

Use a fresh box of rice bubbles or rice krispies - this will ensure your slice is crispy and crunchy!

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.
