2 Cups Cornflakes - 60g (or you can use two weetbix)
Steps
Preheat oven to 180C Bake (350F)
Prepare an 23 or 25 cm square slice tin by greasing - or as I do - lightly spraying with cooking spray and covering in baking paper
Using a food mixer or electric beater cream butter & sugar for 4-5 minutes until creamy
Add flour, cocoa & vanilla and mix well
Add cornflakes and lightly combine.
Spoon into the prepared tin and spread evenly
Bake for 25 minutes, will be soft when removed from the oven
Allow to cool for at least 15 minutes before preparing the icing.
Icing
To prepare your icing - in a medium bowl combine icing sugar, cocoa, vanilla & melted butter and mix
Slowly add the water a little at a time until the desired consistency is reached. If you accidentally add too much water just add a little icing sugar.
Spread the icing over the cooled slice, sprinkle with walnut halves and allow to fully cool and set
Slice & store in an airtight container for 3-4 days.
