Spread unbaked pie crust into a pie pan or use a pre-made crust.
In a large bowl, beat pumpkin puree, sweetened condensed milk, brown sugar, eggs, vanilla, cinnamon, pumpkin pie spice, and salt together.
Pour pumpkin filling into prepared crust and bake for 15 minutes.
Reduce the oven temperature to 350 ℉ and continue to bake pie (leave it in there while the temperature drops) for 35-40 more minutes or until an inserted toothpick comes out clean. To keep edges of the pie crust from burning, wrap the crust with some aluminum foil about half way through baking time and leave it on until the pie is finished baking.
Remove pie from oven and let cool.
Top with whipped cream and serve.
Notes
If you don't have pumpkin pie spice, you can make your own by combining 2 teaspoons ground cinnamon, 1 teaspoon ground ginger, ½ teaspoon ground cloves, and ¼ teaspoon ground nutmeg. Combine all the spices and store in an air-tight container.The edges of the pie crust may burn, so to prevent that wrap the crust with some aluminum foil about half way through baking time and leave it on until the pie is finished baking.Recipe adapted from Eagle Brand.
