Instructions

Slice tin: line a slice tray with 2 sheets of overlapping baking paper. Leave a 2cm overhang on each side. Note 4
Tim tams: add the Tim Tam Biscuits to the bowl of a food processor and blitz for 3-5 seconds so the biscuits are roughly chopped into chunky pieces. Transfer chopped biscuits into a large mixing bowl.
Combine: pour sweetened condensed milk into a heatproof jug and drop in chopped butter pieces. Microwave for 1-3 minutes, stirring in between. Continue to stir until the melted butter and consistently combined with the sweetened condensed milk.
Into slice tray: pour the wet mix over the chopped biscuits and stir to combine. Transfer the wet biscuit mix into the line slice tray and use a rubber spatula to push the mix into the corners and flatten the top. Place in fridge.

Notes

Note 1 - Tim Tams: this is 3 x packets of 11 Tim Tam Biscuits, or 600 grams (200 grams per packet).
Note 2 - Sweetened condensed milk: this is a standard tin of sweetened condensed milk.
Note 3 - Olive oil: we use the olive oil in with the chocolate melts to ensure that the chocolate top of the slice won't crack.
Note 4 - Chocolate topping: don't worry about being too perfect with the chocolate topping. As you work, the chocolate will mix in with the biscuit layer and you can simply smooth it back and forth into 1 chocolate layer.
Note 5 - Slice tin measurements: the slice tray shown in the photos is a 24cm, 9 inch square tray that is 5 cm or 2 inches deep.
