Blend all the dry ingredients and then slowly fold in the wet. Always add the baking powder and baking soda last. Pour into an oiled baking cake pan or bundt pan, as I used, and bake on 350F for 30-35 minutes, until it's golden and you can insert and withdraw a knife or toothpick cleanly from the center.
As it's cooling, make the chocolate sauce by blending all the ingredients until it's a smooth and chocolatey sauce. Spoon over the cake in stripes.
