Put the porridge oats in a saucepan and mix in the cinnamon. Add the almond milk, then turn on the heat.
Meanwhile, mash one banana with a fork, then add it to the pan.
Simmer over low heat for about 6 minutes, stirring occasionally. Add a little more milk, if needed. Turn off the heat, then put a lid on and rest for 5 minutes.
Slice the other banana.
Spoon the porridge into two bowls, and top with the banana.
Scatter the seeds around the bananas, then add the chopped dates.
Drizzle with some maple syrup or honey, if liked.
Serve warm.
