Remove the plastic lid from the ready-made pecan crust. You will want to save this as it can be flipped over and used as a storage lid for your pie.
In a large mixing bowl, beat together the cream cheese and light brown sugar on medium-low speed, using a handheld mixer, for 1 minute or until fluffy and smooth.
To the beaten cream cheese, add the maple syrup and vanilla extract and beat for an additional 30 seconds until fully incorporated.
Fold half (4 ounces) of the whipped topping into the cream cheese mixture until the whipped topping is fully incorporated and no streaks remain.
Fold ¾ cup of the finely chopped toasted pecans into the pecan cream pie mixture until they are evenly distributed.
Spread the pecan cream pie mixture evenly in the ready-made pecan crust.
Top the pecan cream pie with the remaining whipped topping and spread it to all the edges with an offset spatula.
Garnish the center, leaving about an inch around the edge, of the whipped topping with the remaining ¼ cup of toasted finely chopped pecans.
Chill for 6 hours, or up to overnight, to allow the pecan cream pie to set up fully.
