Here is a recipe for Green Tea ShortBread Cookies which I just found but haven't tried yet. You can also look at the green tea recipe for Green Tea Ice Cream.
Green Tea ShortBread Cookies
1 lb unsalted butter (room temperature)
1 cup confectioners' sugar
1 teaspoon salt
2 tablespoons green tea powder (matcha)
4 cups all-purpose flour
Makes 9 dozen small cookies
1 hour 2 minutes 30 mins prep
- Cream butter in the bowl of an electric standing mixer using the paddle attachment; add confectioner's sugar and salt.
- Sift together the tea and flour and add to the butter mixture; mix until just incorporated.
- Roll the dough out to about 1/3-inch thick between 2 pieces of plastic wrap; transfer to a baking sheet and chill until firm, at least 30 minutes.
- Heat oven to 300 degrees.
- Remove top piece of plastic and cut into desired shapes; re-roll excess dough as necessary; transfer to a parchment-lined baking sheet.
- Bake for 16 minutes; rotate pan and bake for another 16 minutes, or until they feel firm when scratched with a fingernail; take care not to let the edges brown; matcha shortbread cookies should maintain their green color.
- Cool, and serve with green-tea or ginger ice cream.
