Line a slice tin with baking paper, leaving a little overhang to make the slice easier to remove.
Add the butter and sweetened condensed milk to a saucepan. Heat gently, stirring until the butter has melted and the mixture is smooth. Remove from the heat.
Add the crushed biscuits, chopped dried apricots, coconut and 2 Tbsp chocolate chips to a large bowl. Mix to combine.
Pour over the warm butter and condensed milk mixture, then stir until everything is evenly coated.
Transfer the mixture to the prepared tin and press down firmly and evenly.
Sprinkle a little extra coconut and chocolate chips over the top, gently pressing them into the surface.
Refrigerate for approximately 2 hours, or until firm.
Lift the slice from the tin using the baking paper, cut into pieces and serve.
