Directions

1. Heat the oven to 350°F and arrange a rack in the lower third.
2. Place a baking sheet on the rack.Lightly flour a work surface and roll the dough out into a round approximately 12 inches in diameter and 1/4 inch thick. Line a 9-inch pie plate with the dough and fold the excess under itself, crimping the edges to seal.
3. Place in the refrigerator while you make the filling.
4. Place the measured flour, cinnamon, allspice, baking powder, cloves, and salt in a small bowl and whisk to combine; set aside.
5. Place the sweet potatoes in a stand mixer fitted with a paddle attachment and mix on medium speed until smooth, about 3 minutes.
6. Add the eggs 1 at a time, letting the first completely incorporate before adding the second. Stop the mixer and scrape down the paddle and sides of the bowl with a rubber spatula.Return the mixer to medium speed, add the sugar, and mix until fully incorporated, about 1 minute. Reduce the speed to low, add the reserved flour mixture, condensed milk, melted butter, and vanilla and mix until just incorporated.
7. Transfer the filling to the crust.
8. Place the pie on the hot baking sheet and bake until the filling is just set in the middle and the edges are puffed, about 50 to 60 minutes.
9. Remove to a wire rack and let cool completely before serving, about 1 hour.
