Step 1

Grease and line the base and side of a 19 x 29cm slice pan with baking paper, allowing the sides to overhang.
Step 2

Combine the butter (50g Coles Organic Unsalted Butter), golden syrup (1 tbsp golden syrup) and three-quarters of the Mars bars in a medium saucepan over low heat. Cook, stirring with a wooden spoon, for 5 minutes or until Mars bars and butter melt and mixture is smooth. Remove from heat.
Step 3

Place the rice bubbles (3 cups (60g) rice bubbles) and remaining Mars bar in a large bowl. Add the Mars bar mixture and stir until well combined. Spoon into the prepared pan and use the back of a spoon to smooth the surface. Set aside for 1 hour to cool completely.
Step 4

Place the chocolate (200g CADBURY Baking Milk Chocolate) and copha (20g copha) in a heatproof bowl over a saucepan half-filled with simmering water, stir until chocolate melts. Pour chocolate over the top of the slice to evenly coat. Set aside for 30 minutes to set. Cut into squares to serve.

Recipe Notes

What are the secrets to a great Mars bar slice?

First rule of a Mars Bar slice? Use fresh rice bubbles. As tempting as it may be to use the half-eaten slightly stale pack in the back of the cupboard, you’ll lose the crispiness that is necessary for this slice. Make sure you press the mixture firmly into the prepared pan. If not, it may crumble when sliced. Also, make sure you melt the butter and Mars Bars over low heat, so the mixture doesn’t catch and burn. If the mixture looks like it’s starting to separate, remove from heat immediately and quickly stir in the rice bubbles.

What is the best way of melting chocolate?

Chocolate can be melted either on the stove top or in the microwave. Water is the natural enemy when melting chocolate as even a drop of can cause your chocolate to “seize” (that is go grainy and clumpy). Some cooks like to use the microwave. To do this, place the chopped chocolate in a microwave-safe bowl and cook in 30 second bursts. Take out and give the chocolate a good stir. Continue until the chocolate is smooth and silky. I’m a bit old school and I prefer to melt chocolate on the stove top. Place the chocolate in a heatproof bowl and set it over a pan of simmering water (don’t let the bowl touch the water). Then turn the heat off and let the chocolate melt slowly, stirring occasionally. This takes longer but ensures no water bubbles over the saucepan and get into the chocolate.

What can I substitute for Copha?

I grew up with Copha always in the fridge – mainly for use in chocolate crackles. When melted with chocolate it gives it an extra sheen and helps it flow more easily onto the top of the slice. Copha also prevents the topping from shattering when sliced. Copha – made from 99% coconut oil -now gets a bad rap as it is hydrogenated, a process that gives products a longer shelf life, but produces trans fats. Most coconut oils have been partially hydrogenated, which makes them slightly healthier. Feel free to use either. I think when you’re only using 20g of Copha and with Mars Bar slice only being an occasional treat it’s okay. I’ve survived!
