I received a request for me to repost my Sugar Cookie recipe. Here is my variation I created in 2011 - Enjoy
2 cups unbleached flour
1 cup of raw sugar
1 1/2 sticks of unsalted butter, room temp
1/4 cup key lime juice
2 tablespoon of key lime zest
1 teaspoon vanilla extract
1/2 teaspoon baking powder
1/4 teaspoon salt
In the stand mixer cream together the butter and the sugar. In another bowl sift together the flour, salt and baking powder. Next add the key lime zest, followed by the key lime juice and the vanilla extract. Once creamy and fluff, slowly add the flour mixture. Remove dough from bowl, wrap in plastic and place in the fridge for at least 2 hours.
Preheat oven to 325 degrees
Divide dough into quarters and roll out to 1/8 to 1/4 thick and cut out into the shape of choice.
Place cookies on parchment lined cookie sheets and bake for about 12 to 15 minutes depending on thickness or until golden brown on the edges. Transfer to cooling rack and decorate as you wish. I often just dust with powdered sugar or make a simple butter cream frosting to mimic a key lime pie.
