Preheat the oven to 350 degrees. Pulse graham crackers and brown sugar in a food processor into a fine crumb. You can also grind them in a zipped top bag with a rolling pin or your hands.
12 whole graham crackers, 5 Tablespoons brown sugar
Simultaneously, pour in the melted salted butter and pulse the graham cracker mixture until the butter is combined. You can also combine them in a bowl with a spatula.
5 Tablespoons salted butter
In a 9 or 10 inch pie dish, press the graham cracker mixture into the bottom and up the sides. Use the bottom of a small glass or measuring cup and your hands to compact the mixture. Bake for 7-8 minutes.
While the pie crust bakes, make the filling. Add the pumpkin, buttermilk, eggs, unsalted butter, brown sugar, granulated sugar, vanilla, salt, cinnamon, ginger, nutmeg, and cloves in a large bowl. Using an electric/stand mixer or a whisk, mix together the filling until well combined.
1 15-ounce can unsweetened pure pumpkin puree, 1 cup buttermilk, 3 eggs, 4 Tablespoons unsalted butter, ¾ cup brown sugar, ¼ cup granulated sugar, 2 teaspoons vanilla extract, ½ teaspoon salt, 2 teaspoons ground cinnamon*, 1 teaspoon ground ginger, ½ teaspoon ground nutmeg, ¼ teaspoon ground cloves
Pour the pumpkin filling into the pre-baked crust.
Use a spatula to smooth out the filling gently. The pie will be filled to the very top.
Bake for 45-55 minutes depending on the size of your pie dish. At the 25-30 minute mark, cover the edges of the pie with foil or a pie crust shield so the edges do not burn. A 9-inch pie will take MORE time than a 10-inch pie. I recommend checking the temperature of the center or pie with a thermometer. It is done when the center is 180-185 degrees. The middle will still look wobbly and unset. It will continue to set as it cools.
Remove from the oven and cool on a wire rack for 2-3 hours. The center will drop and the pie will level as it cools. Cover and transfer to the refrigerator once cooled. Serve with whipped cream.
