  • 2 cups Fiber One cereal (or All Brans)
  • 4 tablespoons melted butter
  • 1 tablespoon corn syrup I think maple syrup or golden syrup would work
  • 1 teaspoon vanilla

Filling and Topping

  • 2 tablespoons cold water
  • 1 tablespoon fresh lime juice
  • 1 1/2 teaspoons unflavored gelatin
  • 4 oz reduced fat cream cheese softened
  • 18 oz Yoplait Fiber One Key lime pie yogurt I had to use a different brand because they were out of this one
  • 1/2 cup reduced fat whipped topping
  • 2 teaspoons grated lime peel


  • Preheat oven to 350°F. Crush cereal in a food processor until it’s the consistency of breadcrumbs. Fiber One says you can do this step with a heavy duty plastic bag, but if you have a food processor it makes the job easier and you get a fine grind.
  • In medium bowl or in the bowl of the food processor, mix crust ingredients until blended. Press crust mixture evenly and firmly in bottom and up side of (well greased!) 9-inch glass pie plate. Bake 10 to 12 minutes or until firm. Cool completely, about 1 hour.
  • In a 1-quart saucepan, mix water and lime juice. Sprinkle gelatin on lime juice mixture; let stand 1 minute. Heat over low heat, stirring constantly, until gelatin is dissolved. Cool slightly, about 2 minutes.
  • In medium bowl, beat cream cheese with electric mixer on medium speed until smooth. Add yogurt and lime juice mixture; beat on medium speed until well blended. Fold in whipped topping and lime peel. At this point, do a taste test and see if you think it’s sweet enough. If not you may want to stir in a tablespoon of powdered sugar.
  • Spoon into crust. Refrigerate until set, about 2 hours.
