M & M Cookies

This recipe was taken from the back of the mini M&M's baking bits package. My kid's love these ones. I used salted butter and omitted the salt.

1 cup (2 sticks) butter or margarine, softened
1/2 cup granulated sugar
1/2 cup firmly packed light brown sugar
1 large egg
1 teaspoon vanilla extract
2 cups all-purpose flour
1/2 teaspoon baking soda
1/8 teaspoon salt
1 275g package (1 1/2 cups) M&M's Chocolate Mini Baking Bits.
3/4 cup chopped nuts (optional)

Preheat oven to 350F.  In a large bowl, cream butter and sugars until light and fluffy; beat in egg and vanilla.  In medium bowl, combine flour, baking soda, and salt; blend into creamed mixture.  Stir in M&M's and nuts, if using.  Drop by heaping tablespoonfuls about 2 inches apart onto ungreased cookie sheets. Bake 10-13 minutes, or until edges are lightly browned and centers are still soft.  Cool one minute on cookie sheets; cool completely on wire racks.  Store in tightly covered container.  Makes about 3 dozen 3-inch cookies.
