This is my first attempt at doing a ruffle icing cake, it was a lot easier than I thought it would be! I used a butter icing (100g of butter, 2 cups of icing sugar, few drops of vanilla essence) Cream butter until fluffy, then add vanilla, add icing sugar slowly. I cut the cake in half and filled with icing then did a crumb icing (I tripled the recipe) let this set. For the ruffle I tripled the icing recipe again. I know it's a lot of icing but finished effect is worth it!
