Whisk ingredients.
Mix the wet ingredients together on medium speed until mixed.
Add to the dry ingredients, the butter, egg whites, vanilla, sour cream and milk. Mix on medium speed mixing only until just blended.
Fill cupcake liners a little more than 3/4’s way.
Bake at 350 degrees for 20-25 minutes.
Allow to cool in the cupcake pan for 10 minutes.
Remove to cooling rack to finish cooling about 30 minutes.
Frost the cupcakes using the large frosting tip and homemade vanilla frosting.
