Ingredients
Method
1.Grease a 20cm x 30cm lamington pan.
2.Process the biscuits until fine. Combine the biscuit crumbs and butter in a medium bowl. Press the mixture evenly into the prepared pan. Cover and refrigerate 30 minutes or until the mixture is firm.
3.Sift the icing sugar into a medium bowl. Stir in the essence, oil and enough of the milk to make a firm, spreadable paste. Spread the paste evenly over the base. Stand until set.
4.Spread combined melted chocolate and extra oil evenly over peppermint layer. Refrigerate until firm. Cut into slices with a large, hot knife.
If the chocolate topping is too firm to cut, stand at room temperature for 30 minutes before slicing.
