Preheat the oven to 360F or 180C. Lightly grease your loaf pan with oil. In a small pot, bring the water to boil, then take off the heat, and add the cacao powder. Stir till the cacao is fully dissolved in the hot water and set aside.
In a bowl, add soy milk, sugar, sunfloweroil, grated orange zest, the melted cacao powder, and mix with a spatula.
Sift in the flour and the bakingpowder and stir until all the ingredients are combined. Try to break some of the larger lumps with the spatula.
Finally, add the darkchocolatechips and give it a quick stir. Transfer the cake batter in the pound cake form and bake for about 50 to 55 minutes. TIP: insert a toothpick in the center of the cake. If it comes out dry, the cake is cooked. If it comes out wet, cook a few more minutes.
Let the pound cake cool down for at least 3 hours before slicing it and eating it. This cake is best eaten 8 hours after it's made. Store in a reusable plastic bag so that it doesn't get dry.
