In a large bowl, mix together the yellow cake mix, pumpkin puree, brown sugar, and pumpkin pie spice until smooth. Be careful not to overmix. A hand mixer can make this easier.

Allow the cake to cool for 15 minutes on a wire rack.

Poke holes all over the top of the cake, about 1 inch apart, going halfway through the cake but not to the bottom. Use the end of a wooden spoon or spatula.
06 -
Evenly pour the sweetened condensed milk over the top, ensuring it fills the holes. Chill the cake in the fridge for 30 minutes.
07 -
After chilling, spread the thawed whipped topping evenly over the cake.
08 -
Sprinkle the toffee bits or Skor bits over the top and drizzle with caramel sauce.
09 -
Place the cake back in the fridge to chill for at least 3 hours, or overnight for best results.
