To make butterscotch pie filling, combine ingredients such as brown sugar, cornstarch, eggs and milk, and cook them over the stove. Food Network offers Paula Deen’s butterscotch pie recipe, which makes use of a ready-made crust, on its website. The recipe serves six to eight people and takes around 30 minutes to prepare.
Prepare butterscotch pie filling by combining 1 1/2 cups brown sugar, 1/2 cup all-purpose flour, 1 tablespoon cornstarch and 1/2 teaspoon salt in a large saucepan over medium heat. Slowly add 4 cups of milk to the mixture, stirring constantly until the mixture thickens.
Temper 2 egg yolks in a separate bowl by whisking in a small portion of the brown sugar mixture. Next, whisk the egg mixture back into the saucepan, and then add 2 tablespoons butter and 2 teaspoons vanilla extract. Cook the mixture for a few minutes, and then remove it from the heat. Pour the pie filling into a dish, and put the dish in the refrigerator.
After the pie filling cools, Food Network recommends pouring the mixture into a ready-made crust and topping with a mixture made by whipping together 1 cup of heavy whipping cream and 1/4 cup powdered sugar. If desired, add 1/4 cup butterscotch morsels to the whipped cream before adding it to the pie, and garnish the pie with additional morsels.
