This cake is so good, no need to use an electric mixer for this it's all mixed by hand in a matter of minutes! This cake is so moist and so chocolaty. If you are a cinnamon lover add in 1 teaspoon. You will love the simplicity, texture and taste of this cake!
In a large bowl sift together both sugars, flour, cocoa powder, baking soda, salt and cinnamon; set aside.
05In another bowl mix/whisk together the melted butter, buttermilk, oil, water, eggs and vanilla; add to the dry ingredients; mix well to combine until you have a smooth batter (I use a large whisk for mixing).
06Add in chocolate chips and nuts (if using).
07Pour into prepared baking dish.
08Bake for about 25-30 minutes or until cake tests done.
09Cool completely before frosting.
10**NOTE** if using nuts reduce amount of chocolate chips to 1/2 cup.
