Brown sugar shortbread.

2 cups butter- softened
1 cup packed brown sugar
4 1/2 cups all-purpose flour
Sugar for sprinkling

Instructions:

Preheat oven to 325 degrees

Using an electric mixer, mix the butter and brown sugar until creamy. Add 3 to 3 3/4 cups flour. Continue to beat with mixers until the dough just comes together.

Sprinkle counter with the remaining flour. Knead for 5 minutes, adding enough flour to make a soft dough. Roll to 1/2 inch thickness. Using a pastry cutter or knife, cut dough into strips or rectangles. (mine were about 3 inches long and 1 1/2 inches thick.) Prick with fork and place on ungreased baking sheets. Sprinkle tops with sugar.

Bake at 325 degrees for 15 minutes or until edges are slightly golden.

After making these tonight, here's my edit.
Add 1/8 teaspoon salt
Roll to 1/4" thickness
Bake 17 minutes at 325

Sounds easy enough. Something for the grandkids to make.

Added some rum turned out great
