EASY PARTY COOKIE RECIPE

1 cup shortening
1 cup brown sugar
1/2 cup granulated sugar
2 teaspoons vanilla
2 eggs
2 1/4 cups sifted all-purpose flour
1 teaspoon soda
1 teaspoon salt
1 1/2 cups M&M’s Plain Chocolate Candies

Blend shortening and sugars. Beat in vanilla and eggs. Sift remaining dry ingredients together; add to the sugar and egg mixture. Mix well. Stir in 1/2 cup M&M’s Plain Chocolate Candies — reserve remaining candies for decorating. Drop from teaspoon onto ungreased cookie sheet–decorate tops of cookies with remaining M&M’s Plain Chocolate Candies as desired.

Bake at 375° for 10-12 mins., until golden brown.

After baking, some of the candies may be slightly cracked. This adds texture and interest to your cookies–still the same delightful flavor. Makes about 6 dozen 2 1/2-inch cookies.
