Ingredients
  

Main Ingredients
  • 1 cup (227g) unsalted butter High-quality, softened to room temperature
  • 1 can (14oz/397g) sweetened condensed milk Room temperature
  • 1 tsp (5ml) pure vanilla extract Optional but recommended
  • 1/4 tsp (1.5g) fine sea salt To balance sweetness

Equipment

  • 1 Stand Mixer Fitted with a paddle or whisk attachment.
  • 1 White Ceramic Bowl Large enough for high-speed whipping.
  • 1 Silver Metal Spoon For testing consistency and dolloping.

Method
 

Preparation and Aeration
  1. In a large white ceramic bowl, beat the softened butter on medium-high speed for 5-8 minutes. The butter should transform from yellow to a pale ivory cream color and appear exceptionally fluffy.
  2. Reduce the mixer speed to medium. Slowly add the sweetened condensed milk one tablespoon at a time, ensuring each addition is fully emulsified before adding the next. The frosting will become glossy and smooth.
  3. Add the vanilla and salt. Turn the mixer to high and whip for another 2 minutes until thick, stable peaks form. If you see soft ridges from the whisk, it is ready.
  4. Finish by hand-folding the frosting with a spatula for 30 seconds to create a silky, dense yet airy consistency.

Notes

Ensure both ingredients are at the exact same room temperature to prevent curdling.
If the frosting splits, warm a small portion and whip it back in to restore the emulsion.
