Lightly warm 2 tablespoons of milk and add the 2 Earl Grey teabags. Leave this to sit for roughly 3 minutes. Pour the remaining 2 tablespoons of milk on top of the tea mixture and leave for 5 minutes. Squeeze the teabags out into the milk for an Earl Grey infused milk.

Add the butter to a mixing bowl and using an electric mixer, blend until creamy.

Add half of the sieved icing sugar to the bowl and using a spoon, gently stir together until just combined (this helps to prevent an icing sugar explosion!), before mixing with the electric mixer.

Add the remaining icing sugar and salt and follow the steps above.

Lastly, add the Earl Grey milk, mixing until completely and thoroughly mixed.
