Making London Fog Cookies is a straightforward process. Just follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

2. Mix Dry Ingredients: In a mixing bowl, combine flour, baking powder, baking soda, salt, and crushed Earl Grey tea leaves. Whisk together until well blended.

3. Cream Butter and Sugars: In a separate large bowl, cream the softened butter, granulated sugar, and brown sugar together until light and fluffy.

4. Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract and finely chopped lavender.

5. Combine Mixtures: Gradually add the dry ingredient mixture to the wet mixture, mixing until just combined. If the dough is too dry, add a tablespoon of milk to achieve the desired consistency.

6. Scoop Cookie Dough: Using a tablespoon or cookie scoop, drop rounded balls of dough onto the prepared baking sheet, leaving space between each cookie.

7. Sprinkle Topping (Optional): If desired, sprinkle a little extra sugar and lavender on top of each dough ball for added sweetness and decoration.

8. Bake: Place the baking sheet in the preheated oven and bake for 12-15 minutes or until the edges are lightly golden.

9. Cool Cookies: Once baked, remove them from the oven and allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.

10. Enjoy: Once cooled, serve these delightful cookies with your favorite tea or coffee!
