Lime Sugar Cookies
Preheat oven to 350 degrees F (180 degrees C). Line cookie sheets with parchment paper or a silicone mat.
Cream together sugar, lime zest, and butter. Beat in egg yolks, lime juice, and vanilla.
Add flour, baking soda, and cream of tartar. Combine.
Form dough into walnut size balls and place 2 inches apart on cookie sheet. Don't flatten. Bake 10-12 minutes, until tops are cracked and just turning color.
Lime Frosting
In a large bowl, cream together the confectioners' sugar and butter until smooth. Gradually mix in the lemon flavoring, lime zest and juice, then add the milk 1 Tbsp at a time until it reaches your desired consistency. Beat until smooth and stiff, about 1 minute.
Frost cookies and serve or store in an airtight container and frost before serving.
