4 level tablespoons/60ml corn flour
6 tablespoons/75g/90ml white sugar
2 cups/500ml milk substitute
1 cup/225ml water
5 tablespoons/37.5g/75ml cocoa
1 teaspoon/5ml vanilla extract
Add all ingredients to a saucepan and whisk vigorously until completely combined and smooth without lumps.
Place the saucepan on the stove on low-medium heat, continue to whisk frequently for about 10 minutes until it slowly brought to the boil. Be careful that the custard does not stick to the bottom of the saucepan.
Take off the heat at this point (It will have thickened but will still be easy to pour).
Allow to sit for 10 minutes to allow to thicken if eating hot or pour into a bowl or ramekin and refrigerate for at least 3 hours until completely set. The set consistency will be similar to a soft jelly.
