This is a copycat recipe of delicious buttery cookies that taste just like Panera's.These cookie will melt in your mouth and are very addicting, so good, you won't be able to eat just one- I have been known to horde these.
Combine all ingredients; use hands to knead until ingredients are blended. Press dough into parchment paper covered 9x13 inch pan to about 1/4 inch thickness.(you may want to grease the pan slightly so the parchment paper does not slide around as you press the dough to 1/4 inch thickness) .
Before baking mark rectangle cookie lines with knife to make them look more authentic Panera shortbread cookie look .
Bake at 325^ for about 20 minutes check after 15 minutes, or until light and not browned. Don't over bake. Cut into cookie squares when cool.
Martha Martin suggests you roll out the dough and use cookie cutters of holiday shapes to make your cookies..Great idea Martha!
