Mary Berry’s Chocolate Buttercream is a classic frosting made from a combination of butter, icing sugar, cocoa powder, and a touch of milk to create a smooth, spreadable consistency. This buttercream is ideal for piping onto cupcakes or frosting layer cakes, offering a creamy, chocolatey richness that complements many types of bakes.
Before starting, ensure the butter is softened at room temperature. This will help the buttercream become smooth and creamy without lumps.
In a large mixing bowl, beat the softened butter with an electric mixer or hand whisk until light and fluffy. This should take about 3-4 minutes.
Gradually sift in the icing sugar and cocoa powder, beating well after each addition to ensure everything is well combined. Start on a low speed to prevent the sugar and cocoa from flying out of the bowl.
Add milk 1 tablespoon at a time, beating well, until the buttercream reaches a smooth, spreadable consistency. If the buttercream is too thick, add more milk; if it’s too thin, add a little more icing sugar.
Once the buttercream is smooth and fluffy, it’s ready to use. Spread it onto cakes, or cupcakes, or use a piping bag to pipe designs.
