Preheat the oven to 350°F (175°C).
In a medium bowl, mix graham cracker crumbs and melted butter until combined.
Press the graham cracker mixture into the bottom of a lasagna pan to form a crust.
Bake the crust in the preheated oven for about 10 minutes or until lightly golden.
In another bowl, beat together cream cheese and powdered sugar until smooth.
Fold in the whipped topping gently until fully combined.
Spread half of the cream cheese mixture over the baked crust.
In a separate bowl, mix together corn syrup, eggs, vanilla extract, salt, and pecans.
Pour this pecan mixture over the cream cheese layer in the lasagna pan.
Finish with the remaining cream cheese mixture, spreading it evenly.
Chill the lasagna in the refrigerator for at least 4 hours or overnight.
When ready to serve, cut into slices and enjoy!
