I think I'll give this one a try

 "The Absolutely Perfect Pumpkin Pie":  

1 (15 oz.) can of pumpkin or about 2 cups of cooked mashed pumpkin  (not pumpkin pie mix)
1 (14 oz.) can of sweetened condensed milk (like Eagle Brand)
2 large eggs
2 Tbs. light brown sugar
1 tsp. vanilla
1 tsp. pumpkin pie spice
1 tsp. cinnamon
1/2 tsp. salt
1 Deep Dish Pie shell, unbaked

Preheat oven to 425 degrees. 

In a mixing bowl, whisk together the pumpkin, sweetened condensed milk, eggs, brown sugar, vanilla, pumpkin pie spice, cinnamon and salt until well blended and smooth. 

Place the pie shell on a cookie sheet and fill with the pumpkin mixture.  It will be full and the cookie sheet aids in moving it to the oven without spilling and also helps the pie bake more evenly.   

Place in the oven and bake at 425 for 10 minutes.  Reduce the oven to 350 and bake for about 40 - 45 minutes.
