Ingredients:
- 1 cup (227g) unsalted butter, slightly cool (65°F)
- 4 cups (500g) confectioners' sugar, sifted
- 3 tbsp (45ml) heavy cream
- 2 tsp (10ml) pure vanilla extract
- 1/4 tsp (1.5g) fine sea salt
Instructions:
- Prep the butter. Place the slightly cool butter (65°F) in the bowl of a stand mixer fitted with a paddle attachment.
- Start the whip. Beat on medium high speed for a full 5 minutes until the butter is pale ivory and visibly fluffy. Scrape the sides of the bowl every 2 minutes to ensure no yellow butter is left at the bottom.
- Slow things down. Reduce the mixer to the lowest speed to prevent a sugar cloud in your kitchen.
- Add the sugar. Gradually add the sifted confectioners' sugar one cup at a time.
- Incorporate thoroughly. Ensure each addition is fully incorporated before adding the next cup. Watch for the mixture to thicken and turn white.
- Add liquids. Pour in the heavy cream, vanilla extract, and fine sea salt while the mixer is still on low.
- Final aeration. Increase speed to medium and beat for another 2 minutes until the texture is velvety and smooth.
- Manual finish. Turn off the mixer and use a rubber spatula to stir the frosting by hand for 30 seconds. This knocks out large air bubbles for a smoother look.
