I have a Fudge Krispies recipe that I got from a magazine several years ago. It's my all time favorite. Maybe this is what you're looking for...

FUDGE KRISPIES

One 11 1/2 oz. pkg. (2 cups) milk chocolate chips
1/2 cup margarine or butter
1/2 cup light corn syrup
2 teaspoons vanilla extract
1 cup sifted confectioner's sugar
4 cups Rice Krispies cereal

Combine milk chocolate chips, margarine, and corn syrup in a medium-size non-stick saucepan. Stir over LOW heat until melted and smooth. Remove from heat. Stir in vanilla extract and sugar. Add rice krispies and mix lightly until well coated. Spread evenly in a 13x9x2-inch non-stick pan. Chill until firm. Cut into 1 1/2-inch squares. Store in refrigerator.
Yield: 48 squares

HINT: I've found that using a large saucepan and adding the rice krispies one cup at a time is much easier for coating evenly.
