In a small mixing bowl, whisk together the egg whites and whole egg and set aside.
In a saucepan, combine the rolled oats, salt and milk of choice and heat until all the liquid is absorbed. Add the egg mixture and whisk well into the oats. Continue stirring for approximately 2-3 minutes, until fully cooked and fluffy. Remove from the heat.
Add the instant coffee, cocoa powder and sweetener and mix until fully incorporated. Refrigerate mixture overnight.
Before eating, combine the cream cheese, cocoa and sweetener in a small bowl. Slowly add in milk until a thick sauce is formed. Top on oatmeal pudding and dig in!
This oatmeal can be eaten warm, but it's best to make overnight for the true tiramisu flavour. Feel free to adjust amount of coffee based on preference- I like it really strong so opt for 2 teaspoons.
