YODA Green Tea Oreos

Happy Halloween! I am Yoda for this year 

INGREDIENTS (about 15 oreos)
3 cups flour
1 tsp baking powder
pinch of salt
1 tbsp green tea powder
2 tsp of lemon zest
1 cup (2 sticks) butter, softened
1 cup sugar
1 egg

INGREDIENTS (filling)
1/2 cup (1 stick) butter, softened
1 cup powdered sugar
2 tsp vanilla extract
 ------------------------------------------------------------------------
DIRECTIONS:
1. In a medium bowl whisk together the flour, baking powder, salt, green tea powder
    and lemon zest. Set aside.
2. In the bowl of an electric mixer beat the butter and sugar until combined. Add the egg.
    Slowly add in the flour until it is incorporated. The dough will form quickly,
    and when it starts to pull away from the bowl, its done.
3. Preheat your oven to 350 degrees. Prep baking sheets with Parchment Papers.
4. Start rolling out the dough. I use powdered sugar instead of flour so it doesn’t get that
    dough-y taste and the sugar adds a slight sweetness. Roll the dough to
    about 1/4 inch thick.
5. Use your cutter to cut out the shapes and transfer onto the Parchment Paper lined
    baking sheet.
6. Bake for 8-10 minutes depending on your oven.
7. Let cool on a wire rack. While the cookies are cooling, start the filling.
8. In the bowl of an electric mixer, beat the butter while carefully adding
    the powdered sugar. Add the vanilla and beat until creamy.
9. Using a piping bag or a spatula, place the filling on the (flat) side of one cookie.
    Use another cookie to press on top and form your ‘sandwich’.
