Crust:
1 cup graham cracker crumbs
3 Tbsp. butter (softened)
3 Tbsp. sugar
Combine these three ingredients and press into the bottom of a 9" springform pan. Bake in a preheated 325° oven for 10 minutes.
4-8 oz. bars cream cheese (softened)
1 cup sugar
3 Tbsp. flour
4 eggs
1 cup sour cream
1 Tbsp. vanilla
With mixer on lowest speed, beat cream cheese VERY gently so as not to incorporate any air into it. Gradually add sugar; then flour. Add eggs one at a time, beating gently still. Fold in sour cream and vanilla. Pour into springform pan. Place springform pan in a shallow dish. Fill with water about 1/3-12 way up side of springform pan. Bake in a preheated 450° oven for 10 minutes. Then reduce heat to 250° and bake 1 hour or until cheesecake is set. Allow cake to stand at room temperature until it is FULLY cooled. Do NOT refrigerate it until it is completely cooled to avoid cracking.
