Bake 20 minutes or until golden brown.
For the Pecan Topping, mix eggs, corn syrup, granulated sugar, butter and vanilla in large bowl until well blended. Stir in pecans. Pour over hot crust.
Bake 25 minutes longer or until topping is slightly firm in the center. Cool in pan on wire rack. Cut into bars.
