Unroll your pie crust into a 9 inch pie plate. Prick the pie crust all over with a fork to prevent the crust from bubbling up when you pre-bake it.
Bake the pie crust in the pre-heated oven for 12-13 minutes or until the edges just start to look golden. Remove from the oven and set aside.
Melt the 4 tablespoons of butter in a sauce pan over medium heat.
Add in the sugar and cornstarch and whisk together with the butter.
Pour in the half and half and continue whisking. The mixture needs to be whisked the entire time or it will scorch on the bottom.
The liquid will start to thicken and begin to boil. Let the mixture boil for 1 whole minute while you continue to stir then remove the pot from the heat.
Add in the vanilla extract and whisk until completely incorporated then pour the filling into the baked pie crust.
Topping
Set your oven to broil.
Melt 2 tablespoons of butter in the microwave and drizzle over the top of the pie. It doesn't need to be perfect as it will spread out in the oven.
Mix together the sugar, cinnamon, and salt and sprinkle it over the melted butter.
Place the pie in the oven and broil for just about 2 minutes. Keep a close eye on it so your crust doesn't burn! (I like to leave the oven door propped open so I can watch carefully.
Let the topping bubble for about 30 seconds then remove the pie from the oven.
Allow to cool to room temperature on the counter then refrigerate for at least 3 hours before serving.
Serve the pie chilled with a side of creamy Tillamook Old Fashioned Vanilla Ice Cream for the perfect pairing!
