Things You'll Need:
1 1/2 lb. confectioners' sugar (1.5 boxes)
1/2 lb. unsalted butter, at room temperature
1/8 cup whole milk, at room temperature
1/2 tbsp. vanilla extract
36 cupcakes (if u have 36)
HOW TO MAKE ICING :)
Place the butter into the mixing bowl.
With a hand-held mixer, whip the butter on high speed until it becomes very soft.
Add 1 cup of sugar into the bowl. After lowering the speed of the mixer, stir the sugar and butter until they are well-combined. Keep adding the sugar 1 cup at a time until all of it is used.
Pour in the milk. Using a low speed, mix the milk into the other ingredients.
Add the vanilla and mix.
Once everything is combined, turn the mixer onto high speed and beat the icing until it is light and fluffy, about 2 to 4 minutes.
Use a small spatula to ice your cupcakes
