Butter Cookies

Ingredients

2 cups all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon salt
1 1/2 sticks (3/4 cup) unsalted butter, softened
1 cup sugar
1 large egg
1/2 teaspoon vanilla

Method

Whisk together flour, baking powder, and salt in a small bowl.

Beat together butter and sugar in a large bowl  for about 6 minutes. Beat in egg and vanilla. Reduce speed to low, then add flour mixture and mix until just combined to form a dough.

Roll the dough and cut it into required shapes and spread them on baking sheets, arranging slices about 1 inch apart.
Preheat oven to 375 degree.
Bake cookies, switching position of sheets halfway through baking, until edges are golden, 12 to 15 minutes total. Let them cool completely.
