Super easy Milo slice based on the good old Weet-Bix slice recipe.  Topped with Milo icing and then finished off with a good sprinkling of Milo.  If you love Milo you will go nuts for this slice.




  • 5 Weet-Bix, crushed (see notes)
  • 1.5 cups Milo
  • 1.5 cups plain flour
  • 2 teaspoons baking poweder
  • 3/4 cup desiccated coconut
  • 3/4 cup golden caster sugar (raw caster sugar)
  • 1 tablespoon golden syrup
  • 200 grams butter
  • 2 teaspoons vanilla bean paste


  • 2 cups icing sugar, sifted
  • 1/2 cup Milo
  • 2 tablespoons boiling water
  • extra Milo to sprinkle on top of slice


  1. Pre-heat oven 180 deg C (360 deg F).  Line 20cm x 30cm (7" x 11") slice tin with baking paper.  

  2. In a large bowl combine Weet-Bix, milo, flour, baking powder and coconut.  Mix well.

  3. In a small saucepan place sugar, golden syrup, butter and vanilla.  Over a low heat stir until butter has melted and sugar has dissolved. 

  4. Pour butter mixture into mixed dry ingredients.  Mix until thoroughly combined.

  5. Press mixture into the lined tin, place in the oven and bake for 20 minutes or until firm.

  6. Once cooked remove from oven and place on cake rack to cool.

  7. Once the base has cooled ice with milo icing and sprinkle with extra milo.  Cut into even pieces and eat!  Store in an airtight container

Milo Icing

  1. Place icing sugar in a medium size bowl.

  2. In a small jug place milo and add 2 tablespoons of boiling water.  Mix well until milo has dissolved.

  3. Pour milo into the icing sugar and mix well.  You may need to add an extra couple of tablespoons of boiling water.  Add one tablespoon at a time and mix well between each addition until you get a thick but spreadable icing consistency.

Recipe Notes

What are Weet-Bix?

Weet-Bix are made in Australia by the company Sanitarium and are a popular breakfast cereal, or you could say cereal brick.

The UK equivalent is Weetabix.  There is no real equivalent in the USA, shredded wheat breakfast "bricks" are the closest I have found.

What is Milo?

As far as I am aware Milo isn't available in the USA.  You can substitute Ovaltine, it is a similar product.  Not as good of course ;)
