For a stronger spice profile, increase the pumpkin pie spice to 3 teaspoons or add an extra 1/2 teaspoon of ground cinnamon and a pinch of ground cloves.
If you prefer a slightly lighter, less sweet top, swap half of the sweetened condensed milk for evaporated milk; the top will still be glossy and softly set, just a bit less sticky. To lean into a more caramel-like flavor, stir 1 teaspoon of vanilla extract into the sweetened condensed milk before pouring it over the batter.
