If you were interested I used my friend's adapted version of Nigella's Cupcake Recipe.
Here is the recipe for the Nutella Icing.
Ingredients
About 40g Butter
2/3 - 1/2 cup of Nutella
1 cup of Pure Icing Sugar
1 tbl milk
Combine butter and nutella. Mix in the milk and icing sugar until the icing sugar is combined.
