Take a loaf pan, line it with parchment paper, and set it aside.

Take a microwave-safe bowl and add the coconut oil, vegan butter, and chocolate chips; cook for 30 seconds, then stir if it's not melted, do another 30 seconds and stir until it melts the rest of the way; it shouldn't need any more time but if it does just be careful not to overcook it.

Add the powdered sugar and soy milk and stir until smooth. Pour it into the prepared pan and place it in the fridge until set up (a couple of hours).

Cut and serve
