1 cup (2 sticks) good quality salted butter, room temperature
1/2 cup brown sugar, packed
2 cups all-purpose flour
Instructions
Preheat oven to 325 degrees.
In the bowl of an electric mixer, cream together softened butter and brown sugar on medium speed until smooth.
Add all-purpose flour and then mix on low speed until fully incorporated and a dough forms. Do not over mix.
Scoop dough out and place on a piece of plastic wrap. Place another sheet of plastic wrap on top of the dough. Roll the dough out into a 6 by 8 inch rectangle, 1/2 inch thick. Use the sides of a ruler to make crisp edges.
Cut the dough with a sharp knife or pizza cutter into (24) 1 by 2 inch rectangles, using the ruler to make even cuts.
Place the rectangles of dough on a baking sheet (all 24 will fit on a half sheet pan) and use a fork to poke holes into the top of the dough.
Bake for 20-23 minutes at 325 degrees. The edges should just be turning golden brown. Remove the baked cookies and transfer them to a cooling rack.
Store in an airtight container for 3-5 days, or freeze for up to 3 months.
