In a small saucepan, add the milk and oats and bring to a simmer over medium-high heat. Then reduce the heat to medium to medium-low and cook, stirring occasionally, until the oats are soft and have absorbed most of the liquid, about 5 minutes.
Add the mashed banana, and oatmeal spice (plus more to taste); stir to combine. Cook for 2 more minutes (feel free to add a little milk, depending on preferred consistency).
Serve into bowls and garnish with banana slices, maple syrup an da sprinkle of oatmeal spice. Enjoy!
