Method
Place the softened unsalted butter into the bowl of a stand mixer fitted with the paddle attachment. Beat on medium-high speed for at least 5 to 7 minutes. The butter should change from a yellow hue to a very pale, almost white colour and become incredibly aerated.
Reduce the mixer speed to the lowest setting. Gradually add the triple-sifted icing sugar one tablespoon at a time. This prevents a 'sugar cloud' and ensures a smooth integration without graininess.
Once all the sugar is incorporated, add the vanilla bean paste, the pinch of salt, and the double cream. The cream provides the luxurious mouthfeel essential for celebration cakes.
Increase the speed to medium and beat for another 2 minutes until perfectly smooth.
To achieve a professional, bubble-free finish for smoothing onto cakes, turn the mixer to the lowest possible speed and let it run for 5 minutes. This 'knocks out' the excess air bubbles created during the high-speed beating.
Use immediately to fill or crumb-coat your sponge layers, or store in an airtight container.
Notes
Always use a paddle attachment rather than a whisk to minimise air bubbles for a smoother finish.
If your buttercream looks too yellow, add a tiny dot of violet food colouring on a toothpick; the purple neutralises the yellow tones for a bright white look.
For the best stability in tiered cakes, ensure your butter is 'cool' room temperature (about 18-20°C), not oily or melting.
Triple-sifting the icing sugar is the secret to a professional texture that won't clog your piping nozzles.
