Remove the cake from the oven and use the bottom of a chopstick or wooden spoon to poke holes throughout the cake, about ⅔ of the way down, ensuring not to poke through the bottom.

Allow the cake to cool for 20-30 minutes.

After the cake has cooled, pour the sweetened and condensed milk evenly over the cake, allowing it to seep into the holes, followed by ½ cup of the caramel sauce.

Spread the whipped topping evenly over the surface of the cooled cake.

Drizzle the remaining ¼ cup caramel sauce in zigzag patterns over the whipped topping. Sprinkle toffee bits and chopped chocolate evenly across the top.
