To a pot off the heat, add 2 cups plant milk, 7 tablespoons sugar, 5 tablespoons cornstarch, and 1 teaspoon vanilla extract. Whisk until smooth.
Stir while on medium heat until the liquid thickens into a creamy custard. It can take between 2 to 5 minutes, depending on the quantities.
When you have almost reached the consistency that you like, take the pot off the heat, add 2 ounces dark chocolate chopped into pieces, and keep stirring for another minute.
Once the chocolate is fullymelted and incorporated your custard is ready.TIP: The custard will keep thickening while off the heat. Keep this in mind and turn off the heat slightly before you reach your desired thickness.
TIP: to check if your custard is ready take a wooden or silicone spatula, dip it in the custard, then run a finger through it. If the spatula stays clean, the custard is ready.
