Oreo or graham cracker pie crust
8 oz. fat free or reg. cream cheese
1/4 cup plain yogurt
1/4 cup crunchy peanut butter
1/2 cup powdered sugar
1/2 tsp. vanilla
1 cup Cool Whip
Mix cream cheese, yogurt, peanut butter, pwd. sugar and vanilla until well blended and then gently fold in the Cool Whip (one half of a regular size tub). If you want to pretty it up, drizzle chocolate over the top. Cover and freeze 2-3 hours and then let sit for 10-15 min before eating.
If you're more ambitious than I, you can make your own crust by mixing graham crackers or Oreo crumbs with 2 tablespoons honey and a little butter. Then spread it out on a pie dish and bake 15-20 minutes until lightly browned.
