Prepare the Cookie Crust
Mix the crushed vanilla wafers or graham crackers with the melted butter until the crumbs are well-coated and resemble wet sand. Press a small layer of the mixture firmly into the bottom of your trifle dish or into the base of individual serving cups for a beautiful presentation.
Create the Cheesecake Filling
In a large bowl, beat the softened cream cheese, powdered sugar, and 1 teaspoon of vanilla extract together until smooth and creamy. Gently fold in the whipped topping, mixing just until everything is light, fluffy, and fully combined. Set aside.
Make the Pecan Pie Layer
Combine brown sugar, corn syrup, heavy cream, and 2 tablespoons of butter in a medium saucepan. Place over medium heat, stirring constantly until the mixture is bubbly and thickened, about 5 to 7 minutes. Remove from heat and stir the chopped pecans and 1 teaspoon of vanilla extract into the warm caramel. Allow the mixture to cool slightly so it thickens further but is still pourable.
Assemble the Trifle
Layer the buttery crust crumbs, then half the cheesecake filling, followed by a generous spoonful of the pecan pie mixture. Repeat layers until you fill your dish, ending with a pretty layer of pecan caramel on top.
Chill to Set
Cover the trifle and refrigerate for at least 2 hours (or overnight for extra flavor) to allow the layers to set and flavors to meld together.
Garnish and Serve
Just before serving, top with swirls of whipped cream and a sprinkle of extra pecans for an elegant finishing touch.
