My friend, Kimberlin, just shared this with me:
– 2 sticks / 1 c. unsalted butter (softened)
– 3/4 cup powdered sugar
– 2 cups flour
– 1/4 tsp salt
Beat butter and sugar until fluffy. Add flour and salt and mix on low (just until combined – do not over mix). I lined an 8×8 baking pan with parchment paper and greased the paper. Press the mixture into the pan evenly (the dough is sticky, so wet your fingers during the process to keep it from sticking to you). Refrigerate for about 30 minutes and then bake at 300 degrees for about 45 min (or until Golden brown). Cool and cut into sticks.
