In a small saucepan over medium-low heat, melt butter and add your BVLGARI Rosa tea leaves. Simmer until the butter has browned and is giving off a lovely rose tea scent. Turn off the heat and allow the butter to cool for 10 minutes. Strain your infused butter through a fine mesh sieve into a cup and make sure you press the leaves to get every last drop of liquid gold.
In a large mixing bowl, whisk to combine flour, salt, and baking soda. In another bowl, whisk to combine your tea infused butter, vanilla, sugar, and egg.
Add the wet ingredients to the dry and mix with a rubber spatula until the dough comes together.
Cover your dough with saran wrap and let it chill in the fridge until the cookie dough is scoopable (about 15 minutes).
Preheat oven to 350 degrees and line your baking tray with parchment paper. Combine sugar and ground tea leaves to make your tea infused sugar. Portion out your cookie dough into 12 balls.
Roll each portion into a ball and roll in the tea sugar until fully coated. Place your cookies on the baking sheet. These cookies do expand a bit, so make sure you have at least 2" between each cookie.
Flatten the cookies slightly with your fingers and bake until just barely golden around the edges, 10 to 12 minutes. Let the cookies to cool on the sheet for 5 minutes before transferring to a wire rack to continue cooling.
Enjoy!
