Ingredients
  

Frosting Base
  • 1 lb (454g) Unsalted Butter Softened to 65°F (18°C)
  • 14 oz (397g) Sweetened Condensed Milk Room temperature, thick and golden
  • 1 tsp Vanilla Extract Optional

Equipment

  • 1 Stand Mixer With whisk or paddle attachment
  • 1 Silicone Spatula For smoothing air bubbles

Method
 

Preparation
  1. Whip the softened unsalted butter on medium-high speed for 5-7 minutes until it turns light ivory and becomes very fluffy.
  2. Slowly stream in the room-temperature sweetened condensed milk in small batches, mixing thoroughly after each addition.
  3. Whip on high for 2 minutes until glossy peaks and silky swirls form. Hand-stir with a spatula to remove air bubbles.

Notes

Ensure butter and milk are at the same room temperature to prevent curdling.
Use high-quality European-style butter for the best glossy finish.
