M & M Sugar Cookies

1 cup butter or margarine
1 cup granulated sugar
1 large egg
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
1 12-ounce package M&M'S® Brand Semi-Sweet Chocolate Mini Baking Bits
Granulated sugar as needed

Preheat oven to 350°F. Cream together butter and sugar until light and fluffy; add egg and vanilla. Combine flour and baking soda; add to creamed mixture just until blended. Stir in M&M'S® Brand Semi-Sweet Chocolate Mini Baking Bits. Shape dough into 1-inch balls. Place on greased cookie sheets about 2 inches apart. With bottom of glass dipped in sugar, flatten dough very slightly so as not to crush M&M'S® Brand Semi-Sweet Chocolate Mini Baking Bits. Bake 10 to 12 minutes or until edges are light golden; let cool 1 minute before transferring to wire rack to cool completely. Store in tightly covered container.
