Place the teabags in 125 ml of boiling water and allow them to steep for 4 minutes. Then remove the teabags so the tea does not become bitter.
Next, place the flour, sugar & salt in a saucepan on the stove over medium heat and stir with a whisk for about 2 minutes until the flour toasts slightly.
Add the earl grey tea & the milk a little at a time, stirring continuously with your whisk to prevent the mixture from burning at the bottom of the saucepan. Using a whisk will minimize any lumps forming.
Add the vanilla extract and salt and continue mixing with your whisk until the mixture thickens.
Once the mixture is thick and goopy (like pudding), remove the saucepan from the heat, and transfer the mixture to a heat-proof container and allow it to cool completely.You can put this container in the fridge or freezer to speed up the cooling process, but make sure the mixture is room temperature before adding it to the butter. Once the pudding has cooled. Place your softened butter in a bowl and whip it up using an electric mixer until it's light and fluffy.
Gradually add the earl grey pudding mixture to the whipped butter, one tablespoon at a time, mixing well after each addition. Make sure each tablespoon of the mixture is incorporated before adding the next tablespoon.
Once all the earl grey pudding and butter is combined, transfer the buttercream to your piping bags and decorate your cupcakes.For these cupcakes I have used a Wilton 1M open star piping nozzle.
