This is an easy recipe and the one and only requirement is long beating. It should be smooth and taste only vanilla. If you can taste the icing sugar, the icing needs to be beaten longer. An electric beater, preferably a standing one, is a necessity. I would not attempt to beat this frosting by hand; the flavour would not develop properly.
6 Tbsp butter, room temperature but not melted
3 cups sifted icing sugar
3 Tbsp milk
1 tsp or more pure vanilla extract
• Beat the butter in a large bowl until very creamy.
• Gradually add the icing sugar, milk and 1 teaspoon of vanilla; beat on low until blended.
• Add more vanilla extract if the frosting is too thick.
• Beat on medium until frosting is light and fluffy.
• Taste it; if you can detect icing sugar, increase the speed to maximum and beat it until the vanilla flavour fully develops.
