Whisk the butter on low speed for a few minutes until it becomes creamy and smooth.
Add half of the icing sugar to the butter. Whisk on medium speed until incorporated.
Next, add the remaining icing sugar, cocoa powder, melted chocolate, a pinch of salt, and double cream. Whisk for 3-5 minutes or until the mixture is spreadable.
Now you have a delightful, fluffy chocolate buttercream that you can use as desired!
Notes
Ingredient Temperature: When making the frosting, it’s best to use ingredients that are at room temperature. This ensures a uniform and creamy texture.Preparation of Dry Ingredients: Prior to mixing in the dry ingredients, sift them through a sieve. This step eliminates any clumps and unwanted particles, leading to a perfect frosting.Melting Chocolate: Place the chocolate in a microwave-safe bowl and heat it in 30-second bursts. Ensure it has cooled down a bit before incorporating it into the frosting.
