Preheat oven to 350 degrees F (177 degrees C).
Whisk together ½ cup of unsalted butter and 1 cup of granulated sugar in a mixing bowl.
Add the egg and 1 tsp of vanilla extract, and mix until combined.
In a separate bowl, whisk together 1 ⅔ cup of all purpose flour, ½ tsp of baking powder, ½ tsp of baking soda, and ½ tsp of salt.
Using a spice grinder, break down 3 tbsp of loose leaf jasmine tea. Add ½ of it to the dry ingredients in step 3 and mix. Set the rest aside.
Pour the dry ingredients into the wet ingredients. Mix until just combined. Be careful not to over mix.
Break down ⅓ cup of freeze-dried strawberries using a spice grinder. Mix together ⅓ cup of granulated sugar, the other half of the jasmine tea, and the powdered, freeze-dried strawberries. Set aside.
Prep 2 baking sheets by covering it with parchment paper.
Scoop out the cookie dough using a medium sized cookie scoop (3 tbsp/#20 cookie scoop). Roll it between your palms until it is in the shape of a ball. Coat it in the strawberry sugar mixture and place it on the prepped baking sheet. Repeat this process until you run out of cookie dough.
Bake for 10-12 minutes.
Once out of the oven, sprinkle leftover strawberry sugar on top (optional). Cool for 10 minutes before transferring to a cooling rack to cool completely.
