Transfer the oat flakes to a saucepan, pour in the milk and cook over low heat for about 15 minutes - until soft (if the milk boils down too much, you can add a little more).
50 g oat flakes, 200 ml milk
Add a tablespoon of peanut butter to the cooked oatmeal and mix thoroughly.
1 tablespoon peanut butter
You can now sweeten the oatmeal to taste - I used peanut butter with white chocolate, so I didn't need to.
erythritol
Transfer the oatmeal to a bowl.
Slice the banana on top.
1 banana
You can also drizzle the top with a little peanut butter and sprinkle with chopped nuts or, like me, chocolate-covered raisins :)
