Soften butter in a mixing bowl.

Add brown sugar to the bowl.

Cream the butter and brown sugar until light and fluffy.

Gradually add 3-3/4 cups of flour.

Mix until well combined.

Sprinkle some of the remaining flour on a board.

Place the butter/sugar/flour mixture on the floured board.

Knead for 5 minutes, adding enough of the remaining flour to make a soft, non-sticky dough.

Roll the dough to 1/2 inch thickness.

Cut the dough into three-inch by one-inch strips.

Place the strips one inch apart on ungreased baking sheets.

Use a fork on a slight angle and prick each strip six times.

Bake at 325 degrees Fahrenheit for 20 to 25 minutes, or until the cookies are lightly browned.

Let cool for a few minutes before serving.
