4 large eggs
1 tsp vanilla extract

Heat oven to 300 degrees.
To make the crust, stir the gingersnaps with half (1/4 cup) butter; press mixture into the bottom of a 9-inch springform pan.
In large mixer bowl, beat the cream cheese, sugar, and 2 tablespoons of the flour at medium speed of mixer for 2 minutes. Add the eggs, vanilla, and salt; beat for 3 more minutes. Pour the batter onto the prepared crust; set aside.
In a small bowl, stir the brown sugar, pecans, and the remaining 4 tablespoons of flour, and the remaining 1/4 cup of butter together until crumbly. Sprinkle mixture around the edges of the cream cheese mixture.
Bake at 300 degrees for 1 hour and 10 minutes or until the center is firm. Turn off the oven and leave the cheesecake in oven for another 30 minutes.
