Preheat your oven to 360° F. Grease a loaf or cake pan with your oil of choice.
Sift the flour, baking powder, baking soda, combine with the sugars, salt, and spices.
In a second bowl, combine the remaining ingredients.
Combine the bowls, mixing completely.
Pour into prepared loaf pans, and bake until an inserted knife or skewer comes away clean, 45 - 50 minutes. Cool completely and cut into bite sized squares. (Note: refrigerating the cake until cold throughout makes cutting it much easier!)
For the glaze:
Whisk together all ingredients. Add more sugar or rice milk as needed to thin or thicken the glaze, depending on your preference.
Allow the cake to cool completely before glazing.
