Whenever I try to make regular white frosting (for cupcakes or a cake), it turns out off-white or even yellowish (I assume from the vanilla extract and the butter). But this buttercream frosting recipe actually comes out white-white! I made it this weekend to frost my Double Vanilla Cupcakes from Simply Recipes.
The trick to making frosting really white is 1) using clear imitation vanilla extract (instead of the regular brown vanilla extract); 2) using an organic brand of butter which is often lighter in color than the regular brands; and 3) using plenty of milk and sugar to lighten it.
White Buttercream Frosting
1/3 cup butter
1/4 teaspoon salt
1 teaspoon clear vanilla extract
3.5 cups sifted confectioners sugar
3-4 tablespoons milk
Cream butter, salt, and vanilla, beating until light and fluffy. Add sugar gradually, beating after each addition. Add 3 tablespoons milk, beating until smooth. Beat in more milk until desired spreading consistency is reached. Makes about 2 1/3 cups of frosting (enough to frost tops and sides of an 8-inch, 2-layer cake or 1 dozen cupcakes).
