For the apple topping: Chore and chop the apple and heat the honey in a saucepan over medium-heat. Put in the apple pieces, add the cinnamon and warm water. Sautée covered with a lid on low heat for about 5 minutes, stirring occasionally, until the apple is slightly softened.
Meanwhile, bring the almond milk in another saucepan to a boil. Add the oats, cinnamon powder, vanilla extract and stir. Lower the heat immediately and cook on the lowest heat point for 2 to 3 minutes while stirring frequently.
Remove from heat and add the ground hazelnuts and flaxseeds. Put into a bowl, jar or glass, sprinkle with toppings of choice and enjoy.
