How to Make Mary Berry Buttercream Icing for Cupcakes

Prepare your equipment: Ensure the butter is fully softened at room temperature before you begin. Sift the icing sugar to remove any lumps for a smooth finish.
Cream the butter: Place the softened butter into a large mixing bowl. Beat with an electric mixer for 2–3 minutes until pale, light, and creamy.
Add the icing sugar gradually: Add half the sifted icing sugar and beat slowly at first to prevent a sugar cloud. Once incorporated, add the remaining icing sugar and continue beating until smooth.
Add flavouring and milk: Pour in the vanilla extract and 1 tablespoon of milk. Beat on medium speed for 2–3 minutes until light and fluffy. Add a little more milk if needed to reach a soft piping consistency.
Pipe or spread: Spoon the buttercream into a piping bag fitted with your chosen nozzle and pipe onto completely cooled cupcakes. Alternatively, spread generously with a palette knife.

Tips for Perfect Buttercream

Why is my buttercream too stiff?

Add a small amount of milk, just a teaspoon at a time, and beat until you reach the desired consistency.

Why does my buttercream look grainy?

This usually happens if the icing sugar was not sifted or the butter was too cold. Beat for a little longer and ensure ingredients are at room temperature.

How do I make my buttercream extra fluffy?

Beat the mixture for a full 3–5 minutes once everything is combined. The extra air creates a lighter texture.

Can I colour this buttercream?

Yes, add gel food colouring a drop at a time after mixing. Beat until evenly blended.

Can I make this without an electric mixer?
