Ingredients
  

Main Ingredients
  • 1 cup Unsalted Butter 227g, high-fat preferred
  • 4 cups Powdered Confectioners' Sugar 500g, sifted
  • 1 tbsp Vanilla Bean Paste 15ml, or extract
  • 2 tbsp Heavy Whipping Cream 30ml, cold
  • 0.5 tsp Fine Sea Salt 3g

Equipment

  • 1 Light-colored stainless steel skillet Crucial for seeing color change.
  • 1 Stand mixer with paddle attachment Prevents excess air bubbles.
  • 1 Fine mesh sifter Ensures smooth texture.

Method
 

Brown the Butter
  1. Place butter in a light skillet over medium heat. Stir constantly as it melts and begins to bubble.
  2. Watch for the foam to subside and amber specks to form at the bottom. Once it smells nutty, remove from heat immediately.
Prepare the Base
  1. Transfer butter and specks to a bowl. Let cool until it is a soft, room-temperature solid (65°F).
  2. Beat the solidified brown butter for 3-5 minutes until it turns a warm ivory color.
Final Assembly
  1. Gradually add sifted powdered sugar on low speed until combined.
  2. Add vanilla, salt, and cream. Beat on medium for 2 minutes, then hand-fold to remove air bubbles.

Notes

Ensure the butter is not liquid when you start whipping, or the frosting will be greasy.
Sifting the sugar is mandatory for the professional 'swirling' look.
