Preheat the oven to 350(f) degrees.

Melt the butter over medium heat. Stirring constantly, continue cooking until the butter begins to foam & has a toasted aroma. Watch carefully as the butter will go from brown to burnt very quickly. Once browned, remove from heat & strain into a mixing bowl.

Whisk in the sugar, eggs, egg yolks, pumpkin, cream, vanilla, pumpkin pie spice & salt until well combined.

Transfer filling to the prepared pie crust. 

Bake for 50 to 55 minutes, until the edges have set & the center still has a slight jiggle. Let rest at room temperature for a minimum of 4 hours. 

Chill until ready to serve. Slice & top with a dollop of whipped cream.
