Prepare Lavender Sugar: In a food processor, pulse together the culinary lavender and granulated sugar until finely ground.

Preheat Oven: Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and ground Earl Grey tea.

Cream Butter and Sugar: In another bowl, beat the very soft unsalted butter and granulated sugar together until light and fluffy.

Add Wet Ingredients: Blend in one large room-temperature egg and the vanilla bean paste to the creamed mixture.

Mix Dough: Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined.

Shape Cookies: Roll the dough into small balls, coat with reserved lavender sugar, and flatten onto the prepared baking sheets.

Bake: Place baking sheets in the oven and bake for 9-10 minutes or until edges are golden.

Make Frosting: Beat the softened cream cheese and remaining butter together until fluffy, then mix in powdered sugar and reserved lavender sugar.

Frost Cookies: Once the cookies are cool, spread the lavender cream cheese frosting on each.
