Ingredients

• 1 cup butter, softened
• 1/2 cup confectioners' sugar
• 1/4 cup cornstarch
• 1 1/2 cups all-purpose flour

Directions

1. Preheat the oven to 375 degrees F (190 degrees C).
2. Whip butter with an electric mixer until fluffy. Stir in the confectioners' sugar, cornstarch, and flour. Beat on low for one minute, then on high for 3 to 4 minutes. Drop cookies by spoonfuls 2 inches apart on an ungreased cookie sheet.
3. Bake for 12 to 15 minutes in the preheated oven. Watch that the edges don't brown too much. Cool on wire racks. Drizzle with thin vanilla icing if desired.
