Mix all ingredients for the oats in a deep, oven friendly dish. Add the milk ¼ cup at a time, you want the oats to be moist (sorry) but you don’t want any surplus liquid in the bottom of the dish (it’ll burn in the oven). Let the mix sit for 5 minutes to absorb some of the moisture from the oats then place in the preheated oven to cook for 20-25 minutes.
Once ready, scoop into a bowl and add toppings/ ingredients to serve.
