I just found this on Taste of Home and I'm SOLD. Seriously, they're SO good. And they're not crisp if you only bake them for 5 min. (and they're soooo tasty!)
* 1/2 cup butter, softened
* 1/2 cup butter-flavored shortening
* 1 cup sugar
* 1 egg
* 1 tablespoon milk
* 2 teaspoons lemon extract
* 1 teaspoon vanilla extract
* 2-1/2 cups all-purpose flour
* 3/4 teaspoon salt
* 1/2 teaspoon baking soda
* Additional sugar
In a large mixing bowl, cream butter, shortening and sugar until light and fluffy. Beat in egg, milk and extracts. Combine the flour, salt and baking soda; gradually add to creamed mixture.
Shape into 1-in. balls or drop by rounded teaspoonfuls 2 in. apart onto ungreased baking sheets. Flatten with a glass dipped in sugar.
Bake at 400° for 9-11 minutes or until edges are lightly browned. Immediately remove to wire racks to cool. Yield: about 6-1/2 dozen.
