Gather the ingredients - * Yellow cake mix * Pumpkin puree * Milk * Oil * Eggs * Pumpkin pie spice * Sweetened condensed milk * Cool whip * Pecans * Toffee * Caramel sauce
Add cake mix, pumpkin puree, milk, oil, eggs, and pumpkin pie spice to a large mixing bowl. Mix until well combined.
Bake in preheated oven for 35-40 minutes or until a toothpick inserted into the center comes out clean.
Immediately poke holes in the warm cake using a skewer or chopstick.
Pour the condensed milk all over the holes. Use a spatula to make sure it is evenly covering the cake.
Allow to cool at room temperature, then transfer to fridge to chill completely for at least 2 hours.
Spread the whipped topping evenly on top of the cake.
Sprinkle pecans and toffee over the cake.
Drizzle with caramel just before serving.
