1baked pie shellstore-bought pie shell baked according to package directions.
1-½cupslight brown sugar
2Tablespoonsall-purpose flour
1-½cupswhole milk
3egg yolks, beatenroom temperature egg yolks
1teaspoonvanilla extract
1teaspooncinnamon
whipped topping for garnish
3Tablespoonsbutter
Instructions
Mix the brown sugar and flour. Set aside.
In another bowl, combine the milk and egg yolks until smooth. Add to the sugar mixture and blend with a whisk.
Pour into a heavy saucepan and cook over medium heat for 15 minutes, stirring occasionally with a whisk. The mixture should be thick (like pudding). Remove from heat. Add vanilla, butter, and cinnamon and stir to blend.
Pour into the pie shell. Let it cool off a little, then chill for at least 1 hour in the refrigerator (overnight is even better!).
Serve pie slice with a dollop of whipped cream and a little sprinkle of cinnamon on top of the whipped cream.
Notes
Blind bake the crust - be sure to bake the crust before filling it. This will ensure the crust doesn't get soggy.Wait to slice it - don't slice the pie while it's still warm because the filling won't be fully set. Wait until the pie is completely chilled (the center of the pie takes longer to chill than the edges).Substitutions - you can use a ready-made graham cracker crust instead of the regular pie crust. It's just as delicious!Make ahead - I recommend making this pie the day before you plan to serve it. That way, the butterscotch filling will be very cold and nicely thickened.Store the pie - the pie should be stored in the refrigerator and eaten within 3 days.
