I have had this recipe forEVER and sadly I can't cite it correctly. I am almost positive that it is from one of my summer school cooking classes I took back in middle school. It's that good that I saved it all this time (more time than I care to admit these days!) and still make it frequently. I have added the chocolate chips to the filling and topping and changed the amounts a bit; but otherwise it's pretty true to the original. What you get is a moist, chocolatey, crumbly piece of cake that's great for breakfast or all throughout the day. Enjoy!
