Preheat the oven to 350 degrees F / 180ºc. Line a 8 or 9 inch cake pan with parchment, or grease well and dust with flour.
In a bowl whisk all the dry ingredients until combined well.
Add the wet ingredients to the bowl and mix until smooth. Pour the batter in the prepared cake pan.
Bake for 30 to 35 minutes or a toothpick from near the center comes out clean. Cool for 10 minutes and remove from pan. Cool completely before slicing.
Add frosting of choice like vegan cream cheese frosting, or with whipped coconut cream and fruit, or make a boozy marmalade glaze.
For the boozy glaze: Mix a tbsp of liquor in a 1/4 cup of orange or apricot marmalade or preserves of choice. Heat for a few minutes until bubbling. Use as glaze or serve with each slice.
For a regular glaze: Use a tbsp orange juice mixed with the marmalade, or mix 2 to 3 tbsp orange juice with a 1/3 cup or more powdered sugar.
For stronger Orange flavor, add zest of a small/medium orange. A must for the zesty flavor.Use finely ground/powdered sugar in this cake. The sugar is in the dry and will feel granulated if it isn't fine enough. Overbaking the cake will make it a bit dry, but it will soften as it cools. Add enough glaze or frosting to add more moisture. For a more moist cake, add another 2 tbsp of oil. You can also make this into a loaf. Add nuts and dried fruit of choice like cranberries/currants and bake for 40 to 45 minutes.
