These are so easy - a little bit of chocolate heaven. I have been making these for over 10 years and have been asked more for this recipe than any other. They are named for a woman that gave a friend the recipe - we never knew Wanda but we love her for sharing this one. One reviewer has suggested I rename these "Chocolate Insanity Bars." :) * Some have had trouble with them being gooey - my advice is to use national brand name condensed milk, not store brand, as it tends to be thicker. Also, keep them refrigerated or in a cooler. Enjoy!
