Preheat oven to 180°C conventional or 160ºC fan-forced. Line a 12-hole muffin tray with paper cases.
Sift the dry ingredients into a large bowl, then add the sugars and stir in.
Add the egg, Meadow Fresh Milk, Olivani Pure Olive Oil and vanilla then beat with a mixer until combined.
Scrape the sides of the bowl then add the boiling water and mix until just combined (the batter will be runny).
Pour the batter into a measuring cup or jug and pour evenly into each paper case until ¾ filled (don’t over fill or the mixture will overflow).
Place in the oven and bake for 20-22 minutes or until a tester inserted in the centre comes out clean.
Mix icing sugar with hot water. Add butter and beat until light and fluffy. Pipe or spread onto muffins.
