For a decadent twist, cover the caramel pecan layer with a layer of melted chocolate or chocolate ganache.
To counterbalance the sweetness and bring out the caramel taste, sprinkle a pinch of flaky sea salt on top of the caramel layer.
For a warm, spicy richness that's ideal for adults, add a dash of whiskey to the caramel sauce.
For a delicious, fall-flavored version, place a layer of caramelized apples underneath the caramel sauce.
For a comforting, seasonal touch, stir toasty spices and pumpkin puree into the cheesecake mixture.
