Basic Buttercream Frosting

3 sticks butter softened to room temperature
1 pound powdered sugar
1/2 tsp pure vanilla extract ( I love Watkins Vanilla for baking)
Beat butter with a mixer on medium high speed until pale and creamy, about 2 minutes. Reduce speed to medium, add sugar, 1/2 cup at a time, beating after each addition, about 5 minutes. (after every 2 additions, increase speed to high, and beat for 10 seconds, then reduce speed to medium high) Add vanilla, and beat until buttercream is smooth. Use immediately, or cover and refrigerate for up to 3 days. (then bring to room temperature and beat on low speed until smooth berore using)
