Bain-marie/double boiler method

1. Add the chocolate chips, soy milk, soy cream, and dark sugar to the bain-marie/double boiler. Stir the mixture with a small silicone spatula or a whisk until the chocolate chips are melted and everything is well combined.

2. Remove the pot with the sauce from the hot water pot and cool it down to room temperature. Once cooled down, pour it into a jar or airtight container. 

Saucepan method

1. In a small saucepan, combine the soy milk and soy cream. Heat the mixture over low-medium heat until it’s warm but not boiling. Stir occasionally to prevent it from sticking to the bottom.
2. Once the mixture is warm, remove the saucepan from the heat, add the dark chocolate chips and brown sugar, and stir gently until everything is well combined. Cool it down to room temperature and pour it into a jar or airtight container. 

Microwave method

1. Add all the ingredients to a heat-proof, microwave-safe bowl and microwave for 30 seconds. Check the temperature and if it’s not warm yet, microwave longer with 10-second intervals, checking each time to ensure it doesn’t heat up too much.
2. Remove from the microwave and stir gently with a small silicone spatula or whisk until smooth and velvety. Cool it down to room temperature and pour it into a jar or airtight container.
