Equipment

slice tin (around 27 x 17cm)
large saucepan
small whisk
small heatproof bowl and spoon

Ingredients

3 Mars bars (47 gram bars)
60 grams butter
2 teaspoons golden syrup (or maple syrup, honey or corn syrup)
1 tablespoon Baileys Irish Cream
3 cups rice bubbles (100 grams)
315 grams milk chocolate (75 grams for slice and 240 grams for topping)
50 grams white chocolate (optional)
powdered green food colouring (optional)

Instructions

Grease a slice tin (around 27 x 17cm) with butter and then line with baking paper, leaving extra on sides (to pull the slice from the tin once cooked).
Break mars bars into pieces with your hands and place into a large saucepan. Add 75 grams of the milk chocolate, butter, golden syrup and Baileys.
Place saucepan over very low heat and stir with a small whisk to combine. Keep stirring until the mixture reaches a smooth, runny consistency. The mixture should resemble melted chocolate, with no lumps.
Take off heat and add rice bubbles to the saucepan, stirring to combine well.
Pour mixture into the prepared slice tin, spreading evenly to the edges and then pressing into the tin firmly with the back of a metal spoon.
Melt remaining chocolate in the microwave using 20 second bursts (check and stir after each burst).
Pour melted chocolate over the slice and angle tin from edge to edge to help chocolate reach each side and corner of the slice tin.
Melt the white chocolate and add enough green powdered food colouring for a pale green colour. Drizzle over top of milk chocolate.
Place slice into fridge for at least 2 hours to set.
Remove slice from tin by lifting edges of baking paper, cut into squares and return to the fridge.

Freezing: It should be okay for a month or two in the freezer if wrapped or placed in an airtight container. Remove from the freezer and allow to defrost before consuming.
