Directions:

1. Bake the Layers:
Prepare the brownie mix, cookie mix, and chocolate cake mix according to their package instructions in separate pans.
Allow all layers to cool completely.
2. Prepare the Creamy Filling:
In a mixing bowl, beat the softened cream cheese, powdered sugar, and vanilla extract until smooth.
Gently fold in the whipped topping until well combined.
Stir in the crushed Oreos if using.
3. Assemble the Cake Base:
In a 9×13-inch baking dish, place the brownie layer on the bottom.
Spread half of the creamy filling evenly over the brownies.
Place the cookie layer on top of the creamy filling.
Spread the remaining creamy filling over the cookie layer.
Finally, place the chocolate cake layer on top.
4. Poke and Fill the Cake:
Use the handle of a wooden spoon to poke holes evenly across the top chocolate cake layer.
Pour the sweetened condensed milk evenly over the cake, letting it seep into the holes.
Follow with the warmed hot fudge sauce, spreading evenly.
5. Add the Topping:
Spread the whipped topping evenly over the entire cake.
Sprinkle the top with crushed Oreos and mini chocolate chips.
Drizzle with additional chocolate sauce if desired.
6. Chill and Serve:
Refrigerate for at least 2 hours (or overnight) to allow the layers to set.
Slice and enjoy!
