A classic slice recipe – this is great if you need to take something for fair, picnic or lunchbox treat. Easy, yummy and lasts well for up to a week.
Preheat oven to 180C and grease and line a lamington slice tin (about 20x30cm).
Combine butter, vanilla and sugar in a small saucepan on medium-low heat and cook, until butter melts into the sugar and you have a lovely smooth mixture.
Remove from heat, whisk in the egg.
Sift the flour and cocoa powder into a bowl, then stir in the oats and coconut.
Fold in the butter/sugar mixture and mix to combine.
Transfer to the prepared tin and smooth surface. Bake for 25 minutes. Then cool completely.
For the icing, combine all ingredients in a small bowl and whisk until smooth. Once slice is cool, spread over evenly and sprinkle with the coconut.
