Add the oats and the powdered peanut butter to a saucepan and stir to evenly coat the oats. Turn on the heat to a low to medium, and add the vanilla soy milk. Cook for about 5 minutes, stirring regularly and do not allow to boil.
Wait until the oats are cooked and ready, then stir in the protein powder (if using). Pour the mix into a bowl. Swirl the jam through the centre of the oats before serving.
