3 sticks + 2 tablespoons (375 grams/13 ounces) unsalted butter, softened and cut into cubes
3 cups sifted (480 grams/1 lb + 1 ounce) confectioners’ sugar (icing, powdered)
3 tablespoons (45 mL) milk
1 vanilla bean, scraped
1 teaspoon (5 mL) pure vanilla extract — I use Nielsen-Massey Vanillas 8-oz. Madagascar Bourbon Vanilla Extract
pinch of salt
1. In the bowl of an electric mixer fitted with the paddle attachment, whip butter for 8 minutes on medium speed (I use “4″ on my KitchenAid). Butter will become very pale & creamy.
2. Add remaining ingredients and mix on low speed for 1 minute, then on medium speed for 6 minutes. Frosting will be very light, creamy, and fluffy.
3. Best used right away.
4. You can eliminate the vanilla bean and use a total of 1 1/2 teaspoons of pure vanilla extract.
