1Preheat your oven to 350°F (175°C).
Cut open the Earl Grey tea bags and empty the tea leaves into a small bowl.
In a large mixing bowl, cream together the unsalted butter and powdered sugar until light and fluffy.
Add the vanilla extract and mix until combined.
In another bowl, whisk together the all-purpose flour, Earl Grey tea leaves, and salt.
Gradually add the dry ingredients to the butter mixture, mixing until a dough forms.
Roll the dough into a log shape, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
Once chilled, slice the dough into 1/4-inch thick rounds and place them on a baking sheet lined with parchment paper.
Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
