1/2 c. chocolate wafer crumbs
1 tbsp. softened butter
3 (8 oz.) pkgs. cream cheese
1 c. sugar
1 1/2 tsp. vanilla extract
5 eggs
2 sqs. semi-sweet chocolate, melted

In a small bowl, combine crumbs and butter. Lightly grease a 9 inch spring form pan. Press crumb mixture evenly over the bottom. Preheat oven to 300 degrees. Put cream cheese, sugar and vanilla in a large mixer bowl. With mixer set at medium speed, beat cheese mixture until smooth.

Add eggs, one at a time, beating well after each addition. Set 1 cup of cheese mixture aside; pour rest into prepared pan. Fold melted chocolate into the cup of reserved cheese mixture. Spoon into pan and cut through in a spiral motion for a marble effect. Bake 50-55 minutes or until set. Remove to wire rack and cool completely. Chill for 2 hours.

FROSTING:

1 (6 oz.) pkg. semi-sweet chocolate chips

With spatula, loosen cheesecake around sides and remove side of pan. Frost top and sides with frosting. Decorate with M & M's or chocolate non-parels. Cover carefully and refrigerate.
