Notes
Whipping the butter extensively helps lighten the butter to start.
Always start with less violet gel color to measure the value. You don't want the buttercream to take on a greyish, blue, or purple color. You only need a tiny bit! The violet gel color off-sets the yellow hue in the butter. Then (for extra brightness) add a few drops of white gel to assist in achieving the whitest buttercream.
Make sure you use clear flavoring to help achieve a whiter buttercream. Colored flavorings won't ruin the buttercream but you're going for white and it won't turn out as white as you'd like.
**For warm climates you can add 1-2 cups of vegetable shortening to stabilize the buttercream. Whip together with the butter before adding any other ingredients. You can also add more flavoring, reduce the whipping cream, and/or sub the cream for a little water as milk or cream can separate in the heat.
