Oats simmered in milk with cinnamon and clove, chilled for two hours and then blended smooth. It is a cold drink served in glasses, not a bowl of porridge.

Avena is a drink
The title on this page said oatmeal, and in English that means a hot bowl of porridge eaten with a spoon.
That is not what this recipe makes. The oats are simmered in milk and water for half an hour, chilled for two hours, and then blended smooth and poured into glasses. It is drunk cold.
In Colombia it is sold in plastic bags on the street, drunk at breakfast or in the middle of the afternoon, and everybody knows what avena means. The most common search that reaches this page is how do you make avena, which is exactly the right question and one the old title never answered.
Two hours, and why
The third step chills it for at least two hours before it goes anywhere near the blender, and it is easy to read that as being about temperature.
It is also about texture. Oats carry on absorbing liquid as they cool, and those two hours are when the drink develops its body. Blended straight off the stove it comes out thin, and then thickens in the fridge afterwards into something you did not plan for.
It will thicken further overnight, so if you make it the day before, keep some milk or water aside to loosen it.
Stir it constantly
The first instruction says constantly and means it. Oat flakes are heavier than milk and they settle, and fifteen minutes over medium heat with a layer of oats on the bottom of the pot is enough to scorch them.
The scorched taste does not stay at the bottom. It goes through the whole batch and there is no fixing it.
Cinnamon and clove
A cinnamon stick and a pinch of clove, added halfway with the sugar and the cream rather than at the start.
They are what make this taste Colombian rather than like plain oat milk, and fifteen minutes at a low simmer is enough for both. Whole cinnamon rather than ground, so it can be lifted out or simply blended in at the end.
