This is a recipe of Sara Moulton.They tasted so good and just melted in mouth.
It requires only few ingredients.
All purpose flour - 2 cups
Baking powder - 1/2 tsp
Salt - 1/2 tsp
Sugar - 1 cup
Unsalted Butter softened at room temperature - 3/4 cup(1 1/2 sticks)
Vanilla extract -1/2 tsp
Egg - 1 at room temperature.
Whisk together flour,baking powder and salt in a bowl.
In another bowl beat the sugar and softened butter until it becomes pale and fluffy.
Now add the egg,vanilla to butter-sugar mixture and beat for about 2 minutes.
Finally add the flour mixture and mix until just combined.
In a parchment paper,roll the dough into a 12 inch log.Wrap it and chill in the refrigerator for 2 hrs.The original recipe calls for chilling the dough for 4 hrs.But mine was firm in about 2 hrs.
Take the dough out and slice into 1/4 inch wide discs.
Place the discs in a parchment-lined tray spacing them about 1 inch apart.
Bake them for about 12 minutes switching tray positions halfway through baking.The cookies are done when they are light golden around the edges.
