Set the oven temperature to 350°F (175°C). Coat a 9x13 pan with non-stick spray so nothing sticks.
02 -
Prepare the cake batter by mixing in the eggs, water, and oil as instructed on the box. Pour into your greased pan and bake for as long as the package asks.
03 -
Take the cake out after baking, let it sit for 10 minutes to cool off. Use the handle of a wooden spoon to create holes evenly across the top, about 1 inch apart.
04 -
In a bowl, whisk together the milk and Oreo pudding powder until smooth. There will be little chunks of Oreo, and that’s totally normal.
05 -
Pour the pudding mix over the entire cake and use a spoon to make sure it gets into the holes you poked earlier. Smooth it out over the top too.
06 -
Pop the cake into the fridge and let it chill completely for around an hour.
07 -
Once the cake is cold, evenly spread out your thawed whipped topping over the top.
08 -
Sprinkle the crushed Oreos on the whipped layer for a topping. Cut into slices and dig in.
