Thumbprint Cookies

One of my favorite cooks - Karla Marshall - brought these over for Christmas. She told me she had taken them to a cookie party just a few days before and they won first prize. They are so not your ordinary thumbprint cookies. They are like a shortbread cookie with a little coconut!!! I just found the recipe and thought I would share.
Jam Thumbprints

3/4 pound (3 sticks) unsalted butter, at room temperature
1 cup sugar
1 teaspoon pure vanilla extract
3 1/2 cups flour
1/4 teaspoon kosher salt
1 egg beaten with 1 tablespoon water, for egg wash
7 ounces sweetened flaked coconut
Raspberry and/or apricot jam

Preheat oven to 350 degrees F.

In an electric mixer fitted with the paddle attachment, cream together the butter and sugar until just combined, and then add the vanilla. Separately, sift together the flour and salt. With the mixer on low speed, add the flour mixture to the creamed butter and sugar. Mix until the dough starts to come together. Dump on a floured board and roll together into a flat disk. Wrap in plastic wrap and chill for 30 minutes.

Roll the dough into 1 1/4-inch balls. (If you have a scale, they should each weigh 1-ounce.) Dip each ball into the egg wash and then roll it in coconut. Place the balls on an ungreased cookie sheet and press a light indentation into the top of each with your finger. Drop 1/4 teaspoon of jam into each indentation. Bake for 20 to 25 minutes, until the coconut is a golden brown. Cool and serve.
