Brown Sugar Shortbread
1 cup butter, softened
1/2 cup dark brown sugar
2 1/4 cups flour
Preheat oven to 140 degrees.
Cream butter and sugar in a large bowl. Gradually stir in flour and mix well.
Turn dough out onto lightly-floured surface and knead until smooth. Place dough on cookie sheet and pat into a rectangle about 1/3" thick measuring approximately 11 x 8 inches. Cut into 2-inch by 1-inch pieces. Prick each piece with fork.
Bake at 300 degrees for about 25 minutes, or until bottoms begin to get lightly brown. Cool on sheet 5 minutes, then remove to rack to cool completely.
