Ingredients
Method
Grease an 18cm x 28cm rectangular slice pan. Line base and sides with baking paper, extending paper 2cm above pan edges.
Sift combined flours and cocoa into a large bowl. Stir in sugar. Make a well in the centre. Add butter, egg and extract. Mix well. Stir in coconut. Press over base of prepared pan.
Cook in a moderate oven (180C) for about 20 minutes, or until firm to touch. Remove. Transfer pan to a wire rack. Stand for 10 minutes.
Meanwhile, to make icing, sift sugar and cocoa into a bowl. Add butter. Stir in about 1 ½ tablespoons hot water to form a smooth, thick consistency.
Pour icing over warm slice. Spread evenly. Sprinkle with Peppermint Crisps. Cool in pan.
Serve cut into squares.
