Ingredients
2 cups softened unsalted butter
4 cups confectioners' sugar
2 tsp milk
1 tbsp pure vanilla extract

Instructions
Combine all ingredients in stand mixer fitted with whisk attachment. Start on low to incorporate confectioners' sugar, then gradually increase to high.
Whip on high speed for 5 minutes, until very pale and very fluffy. This long whipping time is critical for the frosting to be light, satiny, mousse-y and like the most delicious, beautiful-textured vanilla frosting ever.
Pause several times to scrape down sides of mixer bowl while it is beating. The frosting will double in volume and will go from a dull, matte white to a shiny, satiny, fluffy white when it is ready.

This recipe yields enough frosting to frost and fill a two-layer 9″ cake, or 24 cupcakes. If you’d like to frost the cake and then pipe additional details, make 1 1/2 times this recipe.
