THERMOMIX METHOD

Line a baking tray with baking paper. 

Place all base ingredients into mixing bowl and blend 20 sec / speed 8.  The mixture should stick together like a dough, if not, add a tablespoon of water and blend a further 10 sec / speed 8.  Transfer the mixture to the lined tray and press down evenly to form a base, place in the freezer to set. 

Wash and dry the mixing bowl, add all of the icing ingredients and blend 1 min / speed 8, until smooth and creamy.  Remove tray from freezer and pour over icing, set in the fridge or freezer. 

Once the icing is firm, cut into squares and store in the fridge or freezer.
