First you need two 9" round pans to make the cake layers. Preheat your oven per the mix's instructions. Combine cake mix with one package of chocolate pudding mix. Then add your wet ingredients, mix and bake all per the instructions on the box. Remove from oven and let cool in pans for at least 10 minutes. Then remove the two cakes from the pan and let cool for another 10-15 minutes on a wire rack.
