I made this experimenting and it was so good I ate the whole thing. I hope you like it.

8 oz of softened cream cheese
1/2 cup of splenda
4 tbsp. of crunchy peanut butter
2 tbsp. of crushed non salted peanuts

Beat the cream cheese utill smooth and add splenda and beat some more. Add the peanut butter and beat until smooth. Butter a small pan with butter and pour mixture into pan and sprinle with crushed peanuts. Put into freezer and enjoy. I haven't worked out the carbs but I well and report the results.
