Preheat oven to 350 degrees F, and grease two 8-in round cake pans.
Set aside. In a large mixing bowl, combine the flour, cocoa, baking soda, salt, optional chips, and sweetener, and stir very well. In a separate mixing bowl, whisk together all remaining ingredients (except frosting).
Pour wet into dry and stir until just combined, then divide between the cake pans. Bake 25 minutes or until batter has risen and a toothpick in the center of the cake comes out clean.
Allow to cool at least 10 minutes before going around the sides with a knife and inverting the cakes.
Frost one layer, stack the cakes, then refrigerate 30 minutes before frosting the entire cake.
This cake is best if frosted right before serving. Due to the lack of preservatives in the frosting, leftovers are best stored in the refrigerator
