Notes
Recipe Tips
Don’t overbake – the slice should be just set when you remove it. It will firm up as it cools.
Let the melted butter cool slightly before adding egg to avoid scrambling.
If the icing is too thick, add an extra splash of boiling water to loosen.
Sprinkle the coconut on top before the icing sets so it sticks.
Use baking paper to easily lift the slice out of the tin.
Store in an airtight container at room temperature for up to 5 days.
Freeze in a sealed container for up to 3 months. Place baking paper between layers to stop them sticking.
