If you want this dessert to have a consistency more like porridge serve it hot or don’t let it thicken that much when cooking.
Otherwise, let it cool down and put it in the fridge the consistency becomes more similar to pudding.
In case you like to add some fruits, I’d recommend adding them when the pudding is done already.
Red berry compote goes great with it and you can easily prepare it by heating up frozen berries in a pot, adding some water & gelatin and boiling it until it thickens. Then, let it cool down. Holds in the fridge for 1-2 weeks.
You may also try out one of the other optional ingredients, a combination of them or leaving out the cinnamon. I only sprinkled some cacao powder on top here and mixed it in with the spoon afterwards.
