Preheat oven to 350 F. Prepare a baking sheet with parchment paper.
In a mixing bowl, combine all ingredients until thoroughly combined.
Using a medium ice cream spoon, place a heaping scoop of batter on the prepared baking sheet. Repeat until you have 12 cookies.
Bake 10-12 minutes until the edges of the cookies are lightly browned.
Remove from the oven and grate lemon peels over the top of the cookies. Cool the cookies on the baking sheet 10 minutes prior to carefully transferring them to a wire baking rack to cool. They are fragile is you remove them too soon, but the longer they sit the harder they get!
Refrigerate to maintain shape and freshness up to 12 days.
