Prepare a single pie crust.

Place all ingredients in a 2 quart pot, and mix with a wire whisk.

Cook over low heat, stirring occasional, scraping sides and bottom to avoid sticking. When mixture begins to heat keep stirring until it is completely thickened. This will take about 15 – 20 minutes.

Pour into cooled baked shell and refrigerate for several hours before cutting. Top with whipped cream.
