Ingredients

Scale

Cookie Dough

  • 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

Lavender Sugar Coating

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

Lavender 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 the Earl Grey Tea: Measure out 3 tablespoons of Earl Grey tea and pulse it briefly in a spice grinder or food processor to grind the leaves finely. This ensures even distribution of flavor in the cookie dough.
  2. Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and the ground Earl Grey tea until well combined for a uniform dry base.
  3. Cream Butter and Sugar: Using a stand mixer or hand mixer, beat softened unsalted butter and granulated sugar on medium speed for about 3-4 minutes until the mixture is light and fluffy, creating airiness in the dough.
  4. Add Egg and Vanilla: Beat in the room temperature egg and vanilla bean paste until fully incorporated and the batter is smooth and homogenous.
  5. Integrate Dry Ingredients: Gradually add the dry flour mixture to the wet ingredients while mixing on low speed. Mix just until combined to avoid developing gluten that could make the cookies tough.
  6. Make Lavender Sugar: In a small bowl, stir together granulated sugar and culinary lavender. This fragrant sugar will coat the cookie dough balls for added texture and aroma.
  7. Shape and Coat Cookies: Scoop tablespoon-sized dough balls and roll them evenly in the lavender sugar. Arrange the coated dough balls on a parchment-lined baking sheet, spacing them about 2 inches apart to allow for spreading.
  8. Bake the Cookies: Preheat the oven to 350°F (175°C). Bake the cookies for 10-12 minutes until the edges are set and begin to turn golden. Let the cookies cool completely on the baking sheet before frosting.
  9. Prepare Lavender Cream Cheese Frosting: Beat cream cheese and softened butter together until smooth. Gradually add powdered sugar, vanilla bean paste, and optional purple food coloring. Continue beating until the frosting is fluffy and spreadable.
  10. Frost the Cookies: Once cooled, spread or pipe the lavender cream cheese frosting onto each cookie. Allow the frosting to set slightly before serving to enhance texture and flavor.

Notes

  • Grinding the Earl Grey tea finely helps infuse the cookies with a smooth, aromatic flavor without large tea bits.
  • Do not overmix the dough after adding the flour to keep cookies tender and soft.
  • Using room temperature egg and softened butter ensures better incorporation and texture in the dough.
  • Allow cookies to cool completely before frosting to prevent melting and sliding of the frosting.
  • Purple food coloring is optional and can be adjusted to preferred shade for a pretty presentation.
  • Store cookies in an airtight container in the refrigerator to keep the cream cheese frosting fresh, best consumed within 3-4 days.
