I got online and found a flourless recipe for a chocolate roll cake. I figured if I substituted the Sugar it called for with Splenda and the chocolate chips with splenda and cocoa powder and butter, then all would be well.
It is better than I ever hoped for. Now I can have my chocolate fix without any added carbs, except for the little bit of carbs in the Lite Whipped Topping.
Here is the recipe if anyone wants to make it. My boys even liked this better than the Brownies that I made them.
