Chocolate Chip Butter Cookies

Melt butter in microwave oven or double boiler, then stir in vanilla. Cool completely. In a large bowl, combine flour and sugar, then stir in butter mixture and chocolate chips (mixture will be crumbly). Shape dough into 1-inch balls. Place 2 inches apart on ungreased baking sheets and flatten slightly. Bake at 375 degrees for 12 minutes, or until edges begin to brown. Cool on wire racks. Makes 4 dozen.
