Make and bake the cake as directed on box.

Make the pudding as directed on box while you wait for the cake.

When cake is done, and still hot. Make holes on cake using the back of a wooden spoon. (you want to make holes big enough for pudding to go in)

Pour pudding over cake, and press a little so pudding can fill the wholes.

Crumb up the oreo cookies and put it over cake.

Let it cool. Place it in the fridge, so that the pudding can thicken up!

The delicious is ready!! You can try yellow cake with chocolate pudding too!
