Steep Earl Grey tea in a mug and leave the teabag in until tea is cool. You can make the tea in advance and store it in the fridge.
Add whipping cream and sugar to a small bowl and whisk for about five minutes until a soft whipped cream is formed; it should be a pourable consistency.
Pour cooled tea over ice in a glass, add strawberry milk, and top with soft whipped cream. Mix to combine and enjoy!
