Semi-sweet Chocolate Frosting
Inspired by techniques from America's Test Kitchen.
Melted semi-sweet chocolate and cocoa powder are beaten into butter and cream until the frosting turns pale, light and fluffy, giving it a deep chocolate flavour without being overly sweet. It whips up quickly in a stand mixer and spreads smoothly over a cooled cake or cupcakes.
Always check the labels of the products you use.
Method
- 1
Melt the chocolate. Melt the chocolate in a heatproof bowl set over barely simmering water, or in short bursts in the microwave, stirring until smooth. Set aside to cool to room temperature.
- 2
Cream the butter. In a stand mixer fitted with the whisk attachment, beat the butter, cream, vanilla, salt and melted chocolate on medium-high speed until combined.
- 3
Add the sugar and cocoa. Reduce the speed to medium-low. With the mixer running, slowly add the icing sugar and cocoa powder and mix until smooth, 1-2 minutes.
- 4
Whip until fluffy. Increase the speed to medium-high and beat the frosting until light and fluffy, about 5 minutes.
Storage
Store airtight in the refrigerator for up to 5 days, or freeze for up to a month; bring to room temperature and beat briefly before using.
EU nutrition claims
- Low salt: 0.23 g salt per 100 g (limit ≤ 0.3 g)
Per 100 g of the finished dish, worked out from the nutrition per serving and the lowest likely cooked weight (about 57 g a serving), so the true values are, if anything, lower. Thresholds from the Annex to EU Regulation (EC) No 1924/2006. How we decide
