Ingredients:
- 1 cup (2 sticks) unsalted butter, softened to room temperature (226g)
- 3 cups powdered sugar, sifted (360g)
- 6 ounces (170g) dark chocolate (70% cacao or higher), finely chopped
- 1/4 cup heavy cream (60ml)
- 1 teaspoon vanilla extract (5ml)
- 1/4 teaspoon salt (1.5ml)
Instructions:
- Gently melt the dark chocolate and heavy cream together using a double boiler or a heatproof bowl set over a simmering pot of water. Stir frequently until smooth. Remove from heat and let cool slightly. Do not let water touch the bottom of the bowl.
- In a large bowl, beat the softened butter with an electric mixer on medium speed until light and fluffy (about 3-5 minutes).
- Gradually add the sifted powdered sugar to the butter, beating on low speed until combined. Be careful not to create a sugar cloud!
- Slowly pour the slightly cooled melted chocolate into the butter and sugar mixture. Beat on medium speed until well combined.
- Stir in the vanilla extract and salt.
- Increase the mixer speed to medium-high and beat for an additional 2-3 minutes, or until the buttercream is light and fluffy. Scrape down the sides of the bowl as needed.
- Use immediately or store in an airtight container in the refrigerator for up to a week. Bring to room temperature and re-whip before using.
