Notes
Yield: Yield depends on how large you make the cookies.
Lemon poppy seed cookies: Substitutelemon zest for the orange zest.
Optional toppings: I like to press a semi-sweet chocolate chip in the center of each cookie but you can leave them plain, if you prefer, or use another type of chip, such as white chocolate or milk chocolate. Another option is to make a shallow well in the center of each cookie (before you bake them) and fill it with a ½ teaspoon of fruit preserves.
