Classic Butter Cookies

Preheat oven to 350°F (175°C).

In a medium bowl, cream butter, 1/2 cup sugar, vanilla, and lemon zest with an electric mixer. Mix in flour and blend until all ingredients are combined, about 2 minutes.

Divide dough in half and roll into two equal logs about 6-inches in length. Cover in plastic wrap and refrigerate for 15 minutes.

Unwrap dough and slice into 1/4-inch thick rounds. Place on an ungreased cookie sheet, sprinkle with 2 tablespoons granulated sugar.

Bake for 10 to 12 minutes. Do not allow cookies to brown.
