The easy way to do this is to use a boxed chocolate cake mix and a boxed chocolate pudding mix.
But it is just as easy to use a favorite one-bowl chocolate cake and an easy from-scratch pudding recipe such as Hershey’s Quick Creamy Chocolate Pudding, which was what I did, except that I used half a recipe (for both cake and pudding) because I wanted a small cake. But I also wanted a little oommph for the pudding, so I made a few changes…
Prepare the chocolate cake and bake as usual. When the cake is done, remove from the oven and poke holes in it using the handle of a wooden spoon. Start cooking the pudding. When the pudding is done, pour over the hole-ridden cake. Press plastic wrap on the pudding and chill until set.
