  3. Separate your eggs. Set aside. 
  4. In a separate medium mixing bowl, whisk together the butter, vanilla, sour cream and milk. Then whisk in the egg whites. Make sure the mixture is not still too warm from the milk and melted butter before adding in the egg whites. Otherwise it may scramble them. 
  5. Add the wet ingredients to the dry ingredients. Whisk together until just incorporated, you don't want to over-mix. 
  6. Fold in the sprinkles.
  7. Divide the batter evenly among your prepared cupcake liners, filling 2/3 the way full. 
  8. Bake one pan at a time for 18 minutes each or until a toothpick inserted comes out clean. 
  9. Allow the cupcakes to cool completely before frosting. 

For the Buttercream:

  1. In a large mixing bowl, cream the butter with an electric mixer until light and fluffy. 
  2. Add the powdered sugar in one cup at a time, mixing well after each addition. Scrape the bowl as needed. 
  3. Mix in the vanilla, milk, cream and salt until fully incorporated. 
  4. Mix in the food coloring, using a little at a time, until your reach your desired color.
  5. Transfer the buttercream to a piping bag and pipe a dollop onto each of your cooled cupcakes. Add sprinkles or other decorations, if desired. Enjoy!
