For the cookie:  Preheat oven to 350°. Cream butter, sugar, egg, and extracts until smooth. Add flour, baking powder, and salt and mix well. Do not chill dough ~ roll out in one big or several smaller batches, to about ¼ inch thick. Roll out into large rectangle, about ½ inch thick.

Bake at 350° for 12-16 minutes or until slightly golden on edges. Do not over baked.  Cool for 10 minutes in pan. Using a cutting board larger than the pan, gently flip the pan over and cool cookie completely. You may refrigerate until chilled. 

For the frosting: mix all ingredients with a standing or hand mixer. Frost cookie and layer with sliced fruit in the shape of a flag {or any other shape / design you prefer}. Slice and serve.

Store covered in the refrigerator for up to two days.  Enjoy!
