Prepare the Cake:
Follow the instructions on the cake mix box to prepare and bake the cake. Once done, remove from the oven and let it cool for 10 minutes.

Poke Holes in Cake:
Use the back of a spoon to poke holes evenly across the cooled cake.

Add Hot Fudge:
Warm the hot fudge in the microwave until it’s thin enough to pour. Evenly pour the fudge over the cake, allowing it to seep into the holes. Let the cake cool completely.

Make the Pudding Layer:
In a medium bowl, combine the chocolate pudding mix with 1 ¾ cups of milk. Before the pudding sets fully, pour it over the cooled cake. Chill in the fridge for about 20 minutes.

Prepare the Topping:
In another medium bowl, combine the second package of pudding mix with 1 ¾ cups of milk. Refrigerate until fully set, about 10 minutes.

Add Cool Whip:
After the pudding sets, fold in the thawed Cool Whip. Mix in ¾ of the crushed Oreos. Spread the pudding mixture evenly over the chilled cake.

Finish and Serve:
Sprinkle the remaining crushed Oreos on top of the cake. Refrigerate until ready to serve.
