In a large mixing bowl, blend the yellow cake mix with pumpkin puree until a smooth, lump-free batter forms.
02 -
Distribute the batter evenly into two greased 23×33 cm (9×13-inch) baking dishes, or use one dish and slice the cake in half horizontally after baking. Bake in a preheated oven at 175°C for 23 to 28 minutes or until a toothpick inserted into the center emerges clean.
03 -
Allow the baked cake(s) to cool for approximately 10 minutes after removal from the oven.
04 -
Using the handle of a wooden spoon, poke holes uniformly across both cake layers to facilitate soaking.
05 -
Pour half the sweetened condensed milk over the first cake layer and the remainder over the second, ensuring each layer is fully covered and the milk permeates the holes.
06 -
Refrigerate both layers for 30 minutes to allow the condensed milk to be thoroughly absorbed.
07 -
Place the first cake layer onto a serving dish. Evenly spread half of the whipped topping over the surface. Carefully position the second cake layer on top and cover with the remaining whipped topping.
08 -
Generously sprinkle the toffee bits over the final whipped topping layer.
09 -
Finish by drizzling caramel sundae sauce over the entire surface, adjusting the quantity to taste.

Return the assembled cake to the refrigerator for 3 to 4 hours or overnight to allow flavors to develop before serving.
