9 inch single pie crust
2 cups sugar
2 tablespoons flour
½ cup butter, melted
4 eggs, beaten well
½ teaspoon vanilla extract
Preheat the oven to 400 degrees. Line a 9-inch pie pan with crust and then crimp the edges decoratively.
In a large bowl, combine the sugar and flour, mix well. Add the butter, eggs, and vanilla. Stir well to combine everything into a smooth, thick filling. Pour the filling into the piecrust.
Place the pie on the bottom shelf of the oven. Bake for 10 minutes. Lower the heat to 350 degrees, and bake until the center is fairly firm, wiggling only a little when you gently nudge the pan, 30 to 40 minutes.
Place the pie on a cooling rack and let cool to room temperature.
