Ingredients

Scale

For the Earl Grey Cookies:

  • 3 tbsp (12 g) Earl Grey tea
  • 2 3/4 cups (344 g) all purpose flour, spooned and leveled
  • 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1 cup (200 g) granulated white sugar
  • 1 cup (227 g) unsalted butter, softened
  • 1 egg, at room temperature
  • 2 tsp vanilla bean paste

For the Lavender Sugar:

  • 1/2 cup (100 g) granulated white sugar
  • 1/2 tbsp culinary lavender

For the Lavender Cream Cheese Frosting:

  • 4 oz (113 g) cream cheese
  • 1/4 cup (56 g) unsalted butter, softened
  • 1 cup (130 g) powdered sugar
  • 1 tsp vanilla bean paste
  • Purple food coloring (optional)

Instructions

  1. Prepare Lavender Sugar: Add the culinary lavender to a food processor and pulse until it becomes finely ground. Sift through a sieve to remove larger bits, then divide it with half reserved to mix with powdered sugar for frosting and the other half combined with granulated sugar for coating the cookies. Set aside both mixtures.
  2. Preheat Oven: Heat the oven to 350°F (175°C) and line two baking sheets with parchment paper to prepare for baking the cookies.
  3. Grind Earl Grey Tea: Pulse Earl Grey tea leaves in a food processor until finely ground, then sift to remove any large pieces ensuring a smooth incorporation into the dough.
  4. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and finely ground Earl Grey tea to create the dry mixture for the cookies.
  5. Cream Butter and Sugar: Using an electric mixer on high speed, beat the softened unsalted butter and granulated white sugar for 1-2 minutes or until the mixture is light and fluffy.
  6. Add Egg and Vanilla: On medium speed, add the room temperature egg and vanilla bean paste to the butter-sugar mixture. Continue mixing until the mixture is pale and fluffy, approximately 1-2 minutes.
  7. Combine Dry and Wet Ingredients: Gradually add the dry ingredients to the wet ingredients and mix on low speed just until everything is combined, taking care not to overmix.
  8. Form Cookie Balls: Using a 2 tablespoon cookie scoop, scoop the dough and roll each portion into a ball. Coat each ball thoroughly in the prepared lavender sugar.
  9. Arrange Cookies: Place cookie dough balls on the prepared baking sheets, spacing them at least 2 inches apart. Slightly flatten each ball and shape into a neat circle to ensure even baking.
  10. Bake Cookies: Bake in batches of 6-8 for 9-10 minutes. Once baked, let the cookies rest on the baking sheet for 5 minutes. Use a large circular cookie cutter to gently perfect their shape while still warm.
  11. Cool Cookies: Transfer the cookies to a wire rack and allow them to cool completely before frosting.
  12. Prepare Lavender Cream Cheese Frosting: Beat the cream cheese and softened butter together with an electric mixer until fluffy, about 3-4 minutes. Add powdered sugar, the reserved ground lavender, vanilla bean paste, and optional purple food coloring. Continue beating until the frosting is very fluffy.
  13. Frost Cookies: When the cookies are completely cooled, spread about 1 tablespoon of the lavender cream cheese frosting evenly on top of each cookie using a mini offset spatula.
  14. Serve: Enjoy the elegant London Fog Cookies alongside a cup of tea or coffee for a soothing and sophisticated treat.

Notes

  • Measure flour by spooning into the measuring cup and leveling it off to prevent using too much flour, which can cause dense cookies.
  • Finely grinding the Earl Grey tea leaves and lavender helps to distribute their flavors evenly throughout the dough without tough bits.
  • Using room temperature egg and butter ensures the dough creams together smoothly for the best texture.
  • Purple food coloring is optional but adds a pretty lavender hue to the frosting.
  • Allow cookies to cool completely before frosting to prevent frosting from melting.
  • Store frosted cookies in an airtight container in the refrigerator for up to 3 days or freeze them for longer storage.
