In a large mixing bowl, cream together the softened 1 cup unsalted butter and 1/2 cup powdered sugar until light and fluffy. Mix in the 1 tsp vanilla extract.
1 cup unsalted butter, 1/2 cup powdered sugar, 1 tsp vanilla extract
In a separate bowl, whisk together the 2 cups all-purpose flour, 2 tbsp green tea leaves, and 1/4 tsp salt.
2 cups all-purpose flour, 2 tbsp green tea leaves, 1/4 tsp salt
Gradually add the dry ingredients to the butter mixture, mixing until just combined. The dough should be soft but not sticky.
Turn the dough out onto a sheet of plastic wrap, form it into a log, wrap it tightly, and refrigerate for at least 1 hour, or until firm.
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
Once the dough is firm, cut 1/4 inch slices from the log and place them on the prepared baking sheet.
Bake in the preheated oven for 10-12 minutes, or until the edges are just starting to turn golden.
Remove from the oven and allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
In a small saucepan, combine the 1/2 cup fresh raspberries and 1 tbsp lemon juice.

Cook over medium heat, stirring occasionally, until the raspberries break down and release their juices, about 5 minutes.
Strain the raspberry mixture through a fine mesh sieve into a bowl to remove the seeds.
Gradually whisk in the 1 cup powdered sugar until you reach a thick but pourable consistency.
1 cup powdered sugar
Once the cookies are completely cooled, drizzle the raspberry icing over each cookie.
