I've made this recipe twice and received rave reviews both times. It will now become a fixture at holidays. I modified the recipe a little bit by accidentally using non-instant pudding, and in my opinion, it was better - thicker, creamier, tastier. Only suggestion is to let it cool completely before adding the CoolWhip. Another helpful hint is to have everything in separate bowls (ie, flour, sugar, eggs) so as soon as the chocolate comes out of the microwave, it won't harden up. Enjoy!
